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。

                        PackageManager.GET_META_DATA)).toString();

    }

}

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：

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：

  public final void run()

    try

    {

      BasicNameValuePair[] arrayOfBasicNameValuePair = new BasicNameValuePair[4];

      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。
