android 多个shortCut快捷方式实现以及对58同城快捷方式的实现思路的研究

这几天，项目中有个新需求，需要按照模块添加不同的快捷方式到桌面上，从而方便用户的使用。特意进行了研究并分析了下58上面桌面快捷方式的实现。

首先多个shortcut的实现：

<activity
android:name="com.soyoungboy.android.demo.MainActivity"
android:configChanges="keyboardHidden|orientation"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- 瀑布流 -->
<activity
android:name="com.soyoungboy.android.demo.pinterest.PinterestActivity"
android:icon="@drawable/sinkingview_charming"
android:launchMode="singleInstance"
android:process=":process.sub"
android:theme="@android:style/Theme.Light.NoTitleBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>

重点是这里：

android:icon="@drawable/sinkingview_charming"
android:launchMode="singleInstance" -->必须这么写
android:process=":process.sub"--->指定新的进程给对应的activity

<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>

也可指定android:icon来对应这个Activity对应的快捷方式图标。

如果有<category android:name="android.intent.category.LAUNCHER" /> ，那么快捷方式将在启动时创建，也可不设置这行，通过代码去实现。

Activity中创建快捷方式：
这是Activity oncreate()里面的代码：

if (!ShortCutUtils.hasShortcut(getApplicationContext(), "瀑布流")) {
ShortCutUtils.addShortCut(getApplicationContext(),
"com.soyoungboy.android.demo.pinterest.PinterestActivity2",
R.drawable.sinkingview_charming, "瀑布流", "PinterestActivity2");
}

这样就会针对这个Activity创建快捷方式，如果点击启动我们设置在ShortCutIntent中对应的Activity的界面。从而实现多icon,多个执行入口的功能。

然后我们分析下58同城骚当的快捷方式，当然在没看到内部实现远离之前，我是这么认为的。

首先看下界面:



点击后：



后续就是进入对应模块界面了，我就不截图了。

然后反编译下代码，看下怎么实现的。

配置文件里面有如下内容：

<activity android:theme="@style/DialogActivity" android:name="com.wuba.plugins.ThirdFolderActivity" android:taskAffinity="com.wuba.affinity_third_folder" android:screenOrientation="portrait" android:configChanges="locale|keyboardHidden">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>

然后分析LauchActivity的java文件：

<activity android:label="@string/app_name" android:name="com.wuba.activity.launch.LaunchActivity" android:screenOrientation="portrait" android:configChanges="locale|keyboardHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

由上面看出是程序入口：

if ((localView != null) && (localView.getParent() != null))
{
localView.setBackgroundColor(-1);
ImageView localImageView = (ImageView)localView.findViewById(a.g.launch_native_logo);
if (localImageView != null)
localImageView.setImageBitmap(null);
((ViewGroup)localView.getParent()).removeView(localView);
}
super.onDestroy();
}

protected void onNewIntent(Intent paramIntent)
{
super.onNewIntent(paramIntent);
bf.a(this, paramIntent.getStringExtra("random_num"));
}

protected void onResume()
{
super.onResume();
d();
}
}

可以看出红色粗体的那块代码就是卸载当前快捷方式的代码；那么快捷方式在那里创建的呢？那么那个半透明的界面是怎么出来的呢？

不急不急：

通过检索看到b.java文件：

package com.wuba.thirdapps;

import android.content.Context;
import android.content.Intent;
import android.content.Intent.ShortcutIconResource;
import android.content.res.Resources;

final class b
implements Runnable
{
b(ThirdAppApplication paramThirdAppApplication, Context paramContext)
{
}

public final void run()
{
try
{
com.wuba.a locala = ((WubaHybridApplication)(WubaHybridApplication)this.a.getApplicationContext()).c;
BasicNameValuePair[] arrayOfBasicNameValuePair = new BasicNameValuePair[4];
arrayOfBasicNameValuePair[0] = new BasicNameValuePair("ua", ax.d(Build.MANUFACTURER + "#" + Build.MODEL));
arrayOfBasicNameValuePair[1] = new BasicNameValuePair("ver", ax.d(Build.VERSION.RELEASE));
arrayOfBasicNameValuePair[2] = new BasicNameValuePair("sdkver", ax.d(Build.VERSION.SDK));
arrayOfBasicNameValuePair[3] = new BasicNameValuePair("channelid", e.d);
HttpGet localHttpGet = locala.b.a("http://platform.58.com/api/speedy", arrayOfBasicNameValuePair);
bo localbo = (bo)locala.b.a(localHttpGet, new az());
if ((localbo != null) && (localbo.a))
{
Context localContext = this.a;
String str = localContext.getResources().getString(a.k.app_third_folder_name);
if (!at.a(localContext.getApplicationContext(), str))
{
com.wuba.utils.a.a(localContext.getApplicationContext(), "main", "tools", new String[0]);
 Intent localIntent1 = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
localIntent1.putExtra("android.intent.extra.shortcut.NAME", str);
localIntent1.putExtra("duplicate", false);
Intent localIntent2 = new Intent();
localIntent2.setAction("android.intent.action.MAIN");
localIntent2.setClassName(localContext, "com.wuba.plugins.ThirdFolderActivity");
localIntent1.putExtra("android.intent.extra.shortcut.INTENT", localIntent2);
localIntent1.putExtra("android.intent.extra.shortcut.ICON_RESOURCE", Intent.ShortcutIconResource.fromContext(localContext, a.f.wb_app_third_icon));
localContext.sendBroadcast(localIntent1);
new Thread(new com.wuba.utils.d(localContext, str)).start();
}
}
bf.bc(this.a);
return;
}
catch (Exception localException)
{
}
}
}

创建快捷方式，点击快捷方式跳转到ThirdFolderActivity.java界面
由此可知快捷方式是ThirdFolderActivity界面创建的，并且确定点击快捷方式显示的Activity就是ThirdFolderActivity，通过wb_app_third_icon查看drawable下面的资源文件也确定这是58快捷方式的对应的界面。

那么就可知道58骚当入口的实现其实是这样子的：

1，ThirdFolderActivity界面就是点击快捷方式显示的那个半透明的显示7个模块图标的界面，当然跳转肯定是intent的拉。

2，界面半透明效果，style文件如下：

<style name="DialogActivity" parent="@android:style/Theme.Dialog">
<item name="android:windowBackground">@*android:color/transparent</item>
<item name="android:windowFrame">@null</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@*android:style/Animation.Dialog</item>
</style>

3，删除主应用的快捷方式，添加这个界面的快捷方式。

于是一个骚当的快捷方式实现了。
