1、给Launcher添加DockBar
2、修改Launcher长安AllApps的预览图
(1、2两点请参考何明桂何兄的博客,地址分别为:http://blog.csdn.net/hmg25/article/details/6289438 http://blog.csdn.net/hmg25/article/details/6289725)DockBar的实现,何兄只提供了竖屏,我在其博客的评论中看到不少人说是要实现横屏,下面我将我的实现帖出来。主要是修改layout-land/launcher.xml文件,以下是这个文件的全部代码:<com.android.launcherex.DragLayer xmlns:android="http://schemas.android.com/apk/res/android" xmlns:launcher="http://schemas.android.com/apk/res/com.android.launcher" android:id="@+id/drag_layer" android:layout_width="match_parent" android:layout_height="match_parent"> <include layout="@layout/all_apps" /> <!-- The workspace contains 3 screens of cells --> <com.android.launcherex.Workspace android:id="@+id/workspace" android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="horizontal" android:fadeScrollbars="true" launcher:defaultScreen="2"> <include android:id="@+id/cell1" layout="@layout/workspace_screen" /> <include android:id="@+id/cell2" layout="@layout/workspace_screen" /> <include android:id="@+id/cell3" layout="@layout/workspace_screen" /> <include android:id="@+id/cell4" layout="@layout/workspace_screen" /> <include android:id="@+id/cell5" layout="@layout/workspace_screen" /> </com.android.launcherex.Workspace> <RelativeLayout android:id="@+id/dock_layout" android:layout_gravity="bottom|left" android:layout_width="match_parent" android:layout_height="95dip" > <com.android.launcherex.ClippedImageView android:id="@+id/previous_screen" android:layout_width="93dip" android:layout_height="@dimen/button_bar_height" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_marginLeft="6dip" android:scaleType="center" android:src="@drawable/home_arrows_left" android:onClick="previousScreen" launcher:ignoreZone="56dip" android:focusable="true" android:clickable="true" /> <com.android.launcherex.ClippedImageView android:id="@+id/next_screen" android:layout_width="93dip" android:layout_height="@dimen/button_bar_height" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:layout_marginRight="6dip" android:scaleType="center" android:src="@drawable/home_arrows_right" android:onClick="nextScreen" launcher:ignoreZone="-56dip" android:focusable="true" android:clickable="true" /> <com.android.launcherex.DeleteZone android:id="@+id/delete_zone" android:layout_width="@dimen/delete_zone_size" android:layout_height="@dimen/delete_zone_size" android:paddingLeft="@dimen/delete_zone_padding" android:layout_marginBottom="@dimen/dock_bar_height" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:scaleType="center" android:src="@drawable/delete_zone_selector" android:visibility="invisible" launcher:direction="vertical" /> <RelativeLayout android:id="@+id/all_apps_button_cluster" android:layout_height="fill_parent" android:layout_width="@dimen/button_bar_height_portrait" android:layout_gravity="bottom|center_vertical" android:layout_marginBottom="@dimen/half_status_bar_height" > <!-- <com.android.launcherex.HandleView style="@style/HotseatButton" android:id="@+id/all_apps_button" android:layout_centerVertical="true" android:layout_alignParentRight="true" android:src="@drawable/all_apps_button" launcher:direction="vertical" />--> <!-- android:layout_below="@id/all_apps_button" --> <!-- android:layout_above="@id/all_apps_button" --> <ImageView android:id="@+id/hotseat_left" style="@style/HotseatButton.Left" android:src="@drawable/hotseat_phone" android:visibility="gone" android:onClick="launchHotSeat" /> <ImageView android:id="@+id/hotseat_right" style="@style/HotseatButton.Right" android:visibility="gone" android:src="@drawable/hotseat_browser" android:onClick="launchHotSeat" /> </RelativeLayout> <com.android.launcherex.DockBar android:id="@+id/dockbar" android:layout_width="fill_parent" android:layout_height="@dimen/button_bar_height" android:background="@drawable/dock_bg" android:layout_alignParentBottom="true" launcher:direction="horizontal"> <HorizontalScrollView android:id="@+id/dock_scroll_view" android:scrollbars="none" android:fadingEdge="none" android:saveEnabled="false" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="horizontal" android:id="@+id/dock_item_holder" android:saveEnabled="false" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.android.launcherex.HandleView android:id="@+id/all_apps_button" android:layout_centerVertical="true" android:src="@drawable/all_apps_button" launcher:direction="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:focusable="true" android:clickable="true" /> </LinearLayout> </HorizontalScrollView> </com.android.launcherex.DockBar> </RelativeLayout> </com.android.launcherex.DragLayer>
3、启用3D效果
3D效果启动很简单,只需要将all_apps.xml文件下的<include layout="@layout/all_apps_2d" />改为:
<include layout="@layout/all_apps_3d" />
即可。当然你可能还需要对图标做一些调整。我主要是调整了一下几个参数:
public static final int ICON_WIDTH_PX = 64; public static final int ICON_TEXTURE_WIDTH_PX = 74; public static final int SELECTION_TEXTURE_WIDTH_PX = 74 + 20; public static final int ICON_HEIGHT_PX = 64; public static final int ICON_TEXTURE_HEIGHT_PX = 74; public static final int SELECTION_TEXTURE_HEIGHT_PX = 74 + 20;
4、替换应用程序图标
主要是在IconCache中做了以下修改。修改的只是Launcher上显示的图标,长按Home键显示最近开启的应用时,图标还是原先默认的图标,这些就自己去改吧。private CacheEntry cacheLocked(ComponentName componentName, ResolveInfo info) { CacheEntry entry = mCache.get(componentName); if (entry == null) { entry = new CacheEntry(); mCache.put(componentName, entry); entry.title = info.loadLabel(mPackageManager).toString(); if (entry.title == null) { entry.title = info.activityInfo.name; } // entry.icon = Utilities.createIconBitmap(info.activityInfo.loadIcon(mPackageManager), mContext); entry.icon = suBIcon(info); } return entry; } /** * Replace the default Launcher icon * @param info * @return */ private Bitmap suBIcon(ResolveInfo info){ Drawable drawable = null; String pname = info.activityInfo.packageName; if(pname.equals(Constant.PACKAGE_VIDEOPLAYER)){ drawable = mResources.getDrawable(R.drawable.lu_videoplayer); }else if(pname.equals(Constant.PACKAGENAME_BROWSER)){ drawable = mResources.getDrawable(R.drawable.lu_browser); }else if(pname.equals(Constant.PACKAGE_CALCULATOR)){ drawable = mResources.getDrawable(R.drawable.lu_calculator2); }else if(pname.equals(Constant.PACKAGE_CALENDAR)){ drawable = mResources.getDrawable(R.drawable.lu_calendar); }else if(pname.equals(Constant.PACKAGE_CAMERA)){ drawable = mResources.getDrawable(R.drawable.lu_camera); }else if(pname.equals(Constant.PACKAGE_CLOCK)){ drawable = mResources.getDrawable(R.drawable.lu_alarmclock); }else if(pname.equals(Constant.PACKAGE_EMAIL)){ drawable = mResources.getDrawable(R.drawable.lu_email); }else if(pname.equals(Constant.PACKAGE_GALLERY)){ drawable = mResources.getDrawable(R.drawable.lu_gallery); }else if(pname.equals(Constant.PACKAGE_MUSIC)){ drawable = mResources.getDrawable(R.drawable.lu_music); }else if(pname.equals(Constant.PACKAGE_SETTINGS)){ drawable = mResources.getDrawable(R.drawable.lu_settings); } if(drawable!=null){ return Utilities.createIconBitmap(drawable, mContext); }else{ return Utilities.createIconBitmap(info.activityInfo.loadIcon(mPackageManager), mContext); } }
5、批量添加快捷方式
操作:长按桌面 -- Add to Home Screen点击Applications即显示所有安装应用程序列表。可任意选择多个应用程序的快捷方式添加到Launcher上。1、Activity类:AddShortcutsActivity 主要用于显示安装应用程序信息和添加操作界面
2、列表适配: AddShortcutsAdapter 继承BaseAdapter。
3、快捷方式实体类:ShortcutsEntity
4、add_shortcuts_adapter.xml
5、add_shortcuts.xml
直接上代码:
package com.android.launcherex; import java.util.ArrayList; import java.util.List; import android.app.Activity; import android.content.Intent; import android.content.pm.ActivityInfo; import android.content.pm.PackageManager; import android.content.pm.ResolveInfo; import android.os.Bundle; import android.os.Parcelable; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.Button; import android.widget.ListView; import com.android.launcher.R; public class AddShortcutsActivity extends Activity implements OnClickListener,OnItemClickListener{ private AddShortcutsAdapter mShortcutsAdapter; private final static String TAG = "AddShortcutsActivity"; private ListView lstShortcuts; private Button btnAddShortcuts; private Button btnCancelShortcuts; private ArrayList<ShortcutsEntity> mShortcutsEntity = new ArrayList<ShortcutsEntity>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.add_shortcuts); setupViews(); } private void setupViews(){ lstShortcuts = (ListView) findViewById(R.id.shortcuts_list); // lstShortcuts.setItemsCanFocus(false); lstShortcuts.setChoiceMode(ListView.CHOICE_MODE_SINGLE); btnAddShortcuts = (Button) findViewById(R.id.shortcuts_add); btnCancelShortcuts=(Button) findViewById(R.id.shortcuts_cancel); btnAddShortcuts.setOnClickListener(this); btnCancelShortcuts.setOnClickListener(this); lstShortcuts.setOnItemClickListener(this); mShortcutsEntity = getAllShortcuts(); mShortcutsAdapter = new AddShortcutsAdapter(mShortcutsEntity,this); lstShortcuts.setAdapter(mShortcutsAdapter); } public void onClick(View arg0) { switch(arg0.getId()){ case R.id.shortcuts_add: ArrayList<Intent> intents = getSelectedShortcuts(); Intent intent = getIntent(); // Read base intent from extras, otherwise assume default Parcelable parcel = intent.getParcelableExtra(Intent.EXTRA_INTENT); if (parcel instanceof Intent) { intent = (Intent) parcel; } else { intent = new Intent(Intent.ACTION_MAIN, null); intent.addCategory(Intent.CATEGORY_DEFAULT); } Bundle bundle = new Bundle(); bundle.putSerializable("intents", intents); intent.putExtras(bundle); setResult(Activity.RESULT_OK,intent); finish(); break; case R.id.shortcuts_cancel: finish(); break; } } /** * Get all the applications * @return */ private ArrayList<ShortcutsEntity> getAllShortcuts(){ ArrayList<ShortcutsEntity> entitys = new ArrayList<ShortcutsEntity>(); Intent intent = new Intent(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_LAUNCHER); PackageManager mPackageManager = this.getPackageManager(); List<ResolveInfo> mAllApps = mPackageManager.queryIntentActivities(intent, 0); int size = mAllApps.size(); for(int i=0;i<size;i++){ ShortcutsEntity entity = new ShortcutsEntity(); ResolveInfo resolveInfo = mAllApps.get(i); entity.Title = resolveInfo.loadLabel(mPackageManager); entity.Icon = resolveInfo.loadIcon(mPackageManager); entity.Info = resolveInfo; entitys.add(entity); Log.i(TAG, "entity.Title="+resolveInfo.loadLabel(mPackageManager)); } //TODO: sort return entitys; } public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { mShortcutsAdapter.setSelectItem(arg2); mShortcutsAdapter.notifyDataSetChanged(); } /** * Been selected shortcuts * @return */ private ArrayList<Intent> getSelectedShortcuts(){ ArrayList<Intent> selecteds = new ArrayList<Intent>(); ArrayList<Boolean> isCheck = AddShortcutsAdapter.isChecked; int checkSize = isCheck.size(); for(int i=0;i<checkSize;i++){ if(isCheck.get(i)){ ShortcutsEntity entity = mShortcutsEntity.get(i); ActivityInfo activityInfo = entity.Info.activityInfo; Intent intent = new Intent(); intent.setClassName(activityInfo.applicationInfo.packageName,activityInfo.name); selecteds.add(intent); Log.i(TAG, "selected item.name="+mShortcutsEntity.get(i).Title); } } return selecteds; } }
package com.android.launcherex; import java.util.ArrayList; import com.android.launcher.R; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.CheckBox; import android.widget.ImageView; import android.widget.TextView; public class AddShortcutsAdapter extends BaseAdapter { private ArrayList<ShortcutsEntity> mShortcuts; private final LayoutInflater mInflater; private Context mContext; public static ArrayList<Boolean> isChecked; public AddShortcutsAdapter(ArrayList<ShortcutsEntity> shortcuts,Context context) { mShortcuts = shortcuts; mContext = context; mInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); isChecked = new ArrayList<Boolean>(); int size = mShortcuts.size(); for(int i=0;i<size;i++){ isChecked.add(false); } } public int getCount() { if(mShortcuts!=null){ return mShortcuts.size(); } return 0; } public Object getItem(int arg0) { if(mShortcuts!=null){ return mShortcuts.get(arg0); } return null; } public long getItemId(int arg0) { return 0; } public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; ShortcutsEntity entity = mShortcuts.get(position); if(convertView==null){ holder = new ViewHolder(); convertView = mInflater.inflate(R.layout.add_shortcuts_adapter, parent, false); holder.imageView = (ImageView) convertView.findViewById(R.id.sc_icon); holder.textView = (TextView) convertView.findViewById(R.id.sc_title); holder.checkBox = (CheckBox) convertView.findViewById(R.id.sc_checkbox); convertView.setTag(holder); }else{ holder = (ViewHolder) convertView.getTag(); } if(entity!=null){ holder.textView.setText(entity.Title); //TODO: Modify the picture size. holder.imageView.setBackgroundDrawable(Utilities.getDrawable(entity.Icon)); } if(isChecked!=null && !isChecked.isEmpty()){ holder.checkBox.setChecked(isChecked.get(position)); } return convertView; } public void setSelectItem(int item){ if(isChecked.get(item)){ isChecked.set(item, false); }else{ isChecked.set(item,true); } } private class ViewHolder{ ImageView imageView; TextView textView; CheckBox checkBox; } }
package com.android.launcherex; import android.content.pm.ResolveInfo; import android.graphics.drawable.Drawable; public class ShortcutsEntity { public CharSequence Title; public Drawable Icon; public ResolveInfo Info; }
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:id="@+id/sc_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_marginLeft="6dip"/> <TextView android:id="@+id/sc_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_toRightOf="@+id/sc_icon" android:layout_marginLeft="4dip"/> <CheckBox android:id="@+id/sc_checkbox" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentRight="true" android:focusable="false" android:layout_marginRight="6dip"/> </RelativeLayout>
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ListView android:id="@+id/shortcuts_list" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_above="@+id/shortcuts_layout" /> <LinearLayout android:id="@+id/shortcuts_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_alignParentLeft="true" android:layout_alignParentBottom="true" > <Button android:id="@+id/shortcuts_add" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/shortcuts_add_text"/> <Button android:id="@+id/shortcuts_cancel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/shortcuts_cancel_text" /> </LinearLayout> </RelativeLayout>
最后在Launcher.java的onActivityResult方法中添加如下代码,即大功告成
Bundle bundle = data.getExtras(); ArrayList<Intent> intents = (ArrayList<Intent>) bundle.getSerializable("intents"); if (intents != null && !intents.isEmpty()) { int size = intents.size(); for (int i = 0; i < size; i++) { mAddItemCellInfo = new CellLayout.CellInfo(); // Shortcut to solve the problem of overlapping completeAddApplication(this, intents.get(i),mAddItemCellInfo); } } break;
