如何以编程方式在Android中将快捷方式添加到主屏幕

问题描述：

当我开发一个android应用程序时出现了这个问题.我想分享我在开发过程中收集到的知识.

This issue has arisen when I was developing an android application. I thought of sharing the knowledge I gathered during my development.

Android向我们提供了一个意图类com.android.launcher.action.INSTALL_SHORTCUT，可用于向主屏幕添加快捷方式.在下面的代码片段中，我们创建了一个名为MainActivity的活动快捷方式，其名称为HelloWorldShortcut.

Android provide us an intent class com.android.launcher.action.INSTALL_SHORTCUT which can be used to add shortcuts to home screen. In following code snippet we create a shortcut of activity MainActivity with the name HelloWorldShortcut.

首先，我们需要向Android清单xml添加权限INSTALL_SHORTCUT.

First we need to add permission INSTALL_SHORTCUT to android manifest xml.

<uses-permission
        android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />

addShortcut()方法在主屏幕上创建一个新的快捷方式.

The addShortcut() method creates a new shortcut on Home screen.

private void addShortcut() {
    //Adding shortcut for MainActivity 
    //on Home screen
    Intent shortcutIntent = new Intent(getApplicationContext(),
            MainActivity.class);

    shortcutIntent.setAction(Intent.ACTION_MAIN);

    Intent addIntent = new Intent();
    addIntent
            .putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "HelloWorldShortcut");
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
            Intent.ShortcutIconResource.fromContext(getApplicationContext(),
                    R.drawable.ic_launcher));

    addIntent
            .setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    addIntent.putExtra("duplicate", false);  //may it's already there so don't duplicate
    getApplicationContext().sendBroadcast(addIntent);
}

请注意我们如何创建保存目标活动的shortcutIntent对象.该意图对象作为EXTRA_SHORTCUT_INTENT被添加到另一个意图中.

Note how we create shortcutIntent object which holds our target activity. This intent object is added into another intent as EXTRA_SHORTCUT_INTENT.

最后，我们广播了新的意图.这将添加一个快捷方式，其名称提到为 EXTRA_SHORTCUT_NAME和EXTRA_SHORTCUT_ICON_RESOURCE定义的图标.

Finally we broadcast the new intent. This adds a shortcut with name mentioned as EXTRA_SHORTCUT_NAME and icon defined by EXTRA_SHORTCUT_ICON_RESOURCE.

还要放置此代码以避免出现多个快捷方式:

Also put this code to avoid multiple shortcuts :

  if(!getSharedPreferences(Utils.APP_PREFERENCE, Activity.MODE_PRIVATE).getBoolean(Utils.IS_ICON_CREATED, false)){
          addShortcut();
          getSharedPreferences(Utils.APP_PREFERENCE, Activity.MODE_PRIVATE).edit().putBoolean(Utils.IS_ICON_CREATED, true);
      }
