android 实战练习 回归手机卫士 一 主界面布局

学习android一年多了，平常都是看着书，然后做些练习，总觉着学了后面，忘了前面，突然想做一个比较完整一点的项目，

于是不自觉地就想到了做这样一个应用，由于刚接触android没多久，程序肯定会存在或多或少的bug

不过现已大体为准吧，把所有的知识整体地复习和应用一遍也是不错的

以下是效果图









 

今天就先上布局了，相关的业务逻辑后续再说吧

其实这也就是简单的fragment+viewpager的整体布局，然后零零散散地加上一些其他诸如ListView,GridView等布局

1.activity_main.xml主界面

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentTop="true"
android:background="@color/activity_mian_title">
<ImageView

2.activity代码

package cn.edu.gzu.BackPP.activities;

import java.io.File;
import java.util.ArrayList;
import cn.edu.gzu.BackPP.Fragment.IndexFragment;
import cn.edu.gzu.BackPP.Fragment.ManagerFragment;
import cn.edu.gzu.BackPP.Fragment.SettingFragment;
import cn.edu.gzu.BackPP.Fragment.YouhuaFragment;

import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.view.Gravity;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends FragmentActivity implements OnTouchListener{
private Fragment indexFragment;// 获取到fragment实例
private Fragment youhuaFragment;
private Fragment managerFragment;
private Fragment settingFragment;
private ArrayList<Fragment> myFragments;// 由于存放fragment的集合
private ViewPager viewPager;// 让fragment切换并装载的控件
private TextView indexSwitcher;// 页面底部的四个切换组件
private TextView youhusSwitcher;
private TextView managerSwitcher;
private TextView settingSwitcher;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
// 初始化加载fragment
initFragment();
// 通过id找到组件
findViewById();
//在外部存储sdcard上建立文件夹以便后续保存文件
File fileDir=new File(Environment.getExternalStorageDirectory().getPath()+"/HuiGui/cache");
if(!fileDir.exists()){
fileDir.mkdirs();
}

View view = getWindow().getDecorView();
view.setOnTouchListener(this);

startServices();
}

/**
* 初始化加载fragment
*/
private void initFragment() {
myFragments = new ArrayList<Fragment>();
indexFragment = new IndexFragment();
youhuaFragment = new YouhuaFragment();
managerFragment = new ManagerFragment();
settingFragment = new SettingFragment();

// 将fragment实例添加到集合
myFragments.add(indexFragment);
myFragments.add(youhuaFragment);
myFragments.add(managerFragment);
myFragments.add(settingFragment);

viewPager = (ViewPager) findViewById(R.id.activity_main_viewPager);
viewPager.setAdapter(new MyFragmentAdapter(getSupportFragmentManager(),
myFragments));

viewPager.setCurrentItem(0);

viewPager.setOnPageChangeListener(new OnPageChangeListener() {

@Override
public void onPageSelected(int arg0) {
switch (arg0) {
case 0:
initTitleBG();
indexSwitcher.setBackgroundResource(R.drawable.pressed_bg);
break;
case 1:
initTitleBG();
youhusSwitcher.setBackgroundResource(R.drawable.pressed_bg);
break;
case 2:
initTitleBG();
managerSwitcher.setBackgroundResource(R.drawable.pressed_bg);
break;
case 3:
initTitleBG();
settingSwitcher.setBackgroundResource(R.drawable.pressed_bg);
break;
}
}

@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {

}

@Override
public void onPageScrollStateChanged(int arg0) {

}
});

};

/**
* 通过id找到组件
*/
private void findViewById() {
indexSwitcher = (TextView) findViewById(R.id.activity_main_index);
youhusSwitcher = (TextView) findViewById(R.id.activity_main_youhua);
managerSwitcher = (TextView) findViewById(R.id.activity_main_manager);

R.color.activity_mian_bottom_selected));

ViewOnClickListener viewOnClickListener = new ViewOnClickListener();
indexSwitcher.setOnClickListener(viewOnClickListener);
youhusSwitcher.setOnClickListener(viewOnClickListener);
managerSwitcher.setOnClickListener(viewOnClickListener);
settingSwitcher.setOnClickListener(viewOnClickListener);
}

/**

*/
private void initTitleBG() {
indexSwitcher.setBackgroundColor(getResources().getColor(
R.color.activity_mian_title));
youhusSwitcher.setBackgroundColor(getResources().getColor(
R.color.activity_mian_title));
managerSwitcher.setBackgroundColor(getResources().getColor(
R.color.activity_mian_title));
settingSwitcher.setBackgroundColor(getResources().getColor(
R.color.activity_mian_title));
}

/**
* 组件监听其
*/
private class ViewOnClickListener implements OnClickListener {
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.activity_main_index:
viewPager.setCurrentItem(0);
break;
case R.id.activity_main_youhua:

viewPager.setCurrentItem(2);
break;
case R.id.activity_main_setting:
viewPager.setCurrentItem(3);
break;

}
}
}
}

3.建立相应的fragment实例，并加载相应的布局文件，这里只列举其中一页，其他页可相应建立

package cn.edu.gzu.BackPP.Fragment;

import cn.edu.gzu.BackPP.Dao.Const;
import cn.edu.gzu.BackPP.activities.R;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;

public class SettingFragment extends Fragment implements OnClickListener {

@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main_fragment_setting,
container, false);
return view;
}
}

4.xml布局（普通布局文件）

5.fragment适配器

package cn.edu.gzu.BackPP.adapter;

import java.util.ArrayList;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class MyFragmentAdapter extends FragmentPagerAdapter{
private ArrayList<Fragment> myFragments;

public MyFragmentAdapter(FragmentManager fm) {
super(fm);
}
public MyFragmentAdapter(FragmentManager fragmentManager,ArrayList<Fragment> myFragments) {
super(fragmentManager);
this.myFragments=myFragments;
}

@Override
public Fragment getItem(int arg0) {
return myFragments.get(arg0);
}

@Override
public int getCount() {
return myFragments.size();
}

@Override
public int getItemPosition(Object object) {
return super.getItemPosition(object);
}

}

这样就可以实现能左右滑动的主界面了，效果基本上实现如效果图所示，由于其他三页也都是差不多的布局，有时间的话，后续再贴出来

可能界面不是很漂亮，不过目的也就是为了练习，大部分图片都在网上搜的，没办法了
