在应用程序中添加快捷图标

Launcher为了让其他应用程序能够定制自己的快捷图标&＃xff0c;就注册了一个BroadcastReceiver专门接收其他应用程序发来的快捷图标定制信息。所以只需要根据该BroadcastReceiver构造出相对应的Intent并装入我们的定制信息&＃xff0c;最后调用sendBroadcast方法就可以创建一个快捷图标了。那么&＃xff0c;要构造怎样一个Intent才会被Launcher的BroadcastReceiver接收呢&＃xff1f;我们还是先来看看这个BroadcastReceiver的注册信息吧。
下面是Launcher的AndroidManifest.xml文件中Install-ShortcutReceiver的注册信息。


android:name&＃61;”.InstallShortcutReceiver”
android:permission&＃61; “com.android.launcher.permission.INSTALL_SHORTCUT”>
<intent-filter>

intent-filter>

如何向这个 BroadcastReceiver 发送广播&＃xff0c;设置如下&＃xff1a;

  1.首先应用程序必须要有com.android.launcher.permission.INSTALL_SHORTCUT权限&＃xff1b;

2..然后广播出去的Intent的action设置com.android.launcher.action.INSTALL_SHORTCUT&＃xff1b;

  3.这样广播就可以发送给Launcher的InstallShortcutReceiver了&＃xff1b;

而快捷图标的信息则是以附加信息的形式存储在广播出去的Intent对象中的&＃xff0c;包括有图标、显示的名称以及用来启动目标组件的Intent这三种信息。我们可以通过putExtra的重载方法&＃xff0c;通过指定相应的键值&＃xff0c;将这些信息放到附加信息的Bundle对象中。

列出了各种快捷图标信息相对应的键值和数据类型&＃xff1a;

下面举些具体的例子&＃xff0c;如下&＃xff1a;

private final String ACTION_ADD_SHORTCUT &＃61;
“com.android.launcher.action.INSTALL_SHORTCUT”;
Intent addShortcut &＃61;new Intent(ACTION_ADD_SHORTCUT);
String numToDial &＃61; null;
Parcelable icon &＃61; null;

numToDial &＃61; “110″;
icon &＃61; Intent.ShortcutIconResource.fromContext(this,R.drawable.jing);

//numToDial &＃61; “119″;
//icon &＃61; Intent.ShortcutIconResource.fromContext(this,R.drawable.huo);

//图标
addShortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,icon);

//名称
addShortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME,numToDial);

//启动目标组件的Intent
Intent directCall;
directCall.setData(Uri.parse(“tel://”&＃43;numToDial));
addShortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT,directCall);
sendBroadcast(addShortcut);
上面的程序运行后的界面如下&＃xff1a;

只要知道这些信息后&＃xff0c;你就可以轻而易举的为应用程序添加快捷图标。
