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。
ShortCutUtils.java
import java.util.List; import android.content.Context; import android.content.Intent; import android.content.Intent.ShortcutIconResource; import android.content.pm.PackageInfo; import android.content.pm.PackageManager; import android.content.pm.PackageManager.NameNotFoundException; import android.content.pm.ProviderInfo; import android.database.Cursor; import android.net.Uri; import android.text.TextUtils; import android.util.Log;

try { if (appName == null) { // 获取当前应用名称 appName = obtatinAppName(context); } } catch (NameNotFoundException e) { Log.e("ShortCutUtils==>addShortCut", "NameNotFoundException :" + e.toString()); } // 添加快捷方式的名字 shortCutIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, appName); // 不允许重复添加 shortCutIntent.putExtra("duplicate", false); if (className == null) { className = context.getClass().getName(); } // 在里面的intent添加参数 shortCutIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent().setClassName(context.getPackageName(), className) .putExtra("ShortCutExtra", extra)); // 添加快捷方式的图标 ShortcutIconResource iconRes = Intent.ShortcutIconResource.fromContext( context, resourceId); shortCutIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconRes); context.sendBroadcast(shortCutIntent); } /** * 删除桌面上的快捷方式，需要添加权限 <uses-permission * android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" /> * * @param context * @param className * @param appName */ public static void delShortcut(Context context, String className, String appName) { Intent shortcut = new Intent(SHORTCUT_DEL_ACTION);

if (className == null) { className = context.getClass().getName(); } shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent( Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER) .setClassName(context.getPackageName(), className)); context.sendBroadcast(shortcut); } /** * 判断桌面上是否有快捷方式，调用此方法需要添加权限 <uses-permission * android:name="com.android.launcher.permission.READ_SETTINGS" /> * * @param context * @return * @throws NameNotFoundException */ public static boolean hasShortcut(Context context, String appName) { String AUTHORITY = getAuthorityFromPermission(context, READ_SETTINGS_PERMISSION);

} Cursor c = context.getContentResolver().query(CONTENT_URI, new String[] { "title" }, "title=?", new String[] { appName }, null); if (c != null && c.getCount() > 0) { return true; } return false; } /** * android系统桌面的基本信息由一个launcher.db的Sqlite数据库管理，里面有三张表 * 其中一张表就是favorites。这个db文件一般放在data * /data/com.android.launcher(launcher2)文件的databases下 但是对于不同的rom会放在不同的地方 * 例如MIUI放在data/data/com.miui.home/databases下面 * htc放在data/data/com.htc.launcher/databases下面 * * @param context * @param permission * 读取设置的权限 READ_SETTINGS_PERMISSION * @return */ private static String getAuthorityFromPermission(Context context, String permission) { if (TextUtils.isEmpty(permission)) { return null; } List<PackageInfo> packs = context.getPackageManager() .getInstalledPackages(PackageManager.GET_PROVIDERS); if (packs == null) { return null; } for (PackageInfo pack : packs) { ProviderInfo[] providers = pack.providers; if (providers != null) { for (ProviderInfo provider : providers) { if (permission.equals(provider.readPermission) || permission.equals(provider.writePermission)) { return provider.authority; } } } } return null; } /** * 获取应用的名称 * * @param context * @return * @throws NameNotFoundException */ private static String obtatinAppName(Context context) throws NameNotFoundException { PackageManager packageManager = context.getPackageManager(); return packageManager.getApplicationLabel( packageManager.getApplicationInfo(context.getPackageName(), 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：
package com.wuba.thirdapps; import android.content.Context; import android.content.Intent; import android.content.Intent.ShortcutIconResource; import android.content.res.Resources; import android.os.Build; import android.os.Build.VERSION; import com.wuba.android.lib.util.commons.e; import com.wuba.application.WubaHybridApplication; import com.wuba.f.a.f; import com.wuba.f.a.k; import com.wuba.g.az; import com.wuba.model.bo; import com.wuba.utils.at; import com.wuba.utils.ax; import com.wuba.utils.bf; import org.apache.http.client.methods.HttpGet; import org.apache.http.message.BasicNameValuePair; 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。
