Android创建桌面快捷方式和判断当前快捷方式是否已经存在

public static boolean hasShortCut(Context context) {
String url = "";
if (android.os.Build.VERSION.SDK_INT < 8) {
url = "content://com.android.launcher.settings/favorites?notify=true";
} else {
url = "content://com.android.launcher2.settings/favorites?notify=true";
}
ContentResolver resolver = context.getContentResolver();
Cursor cursor = resolver.query(Uri.parse(url), null, "title=?",
new String[] { context.getString(R.string.app_name) }, null);
if (cursor != null && cursor.moveToFirst()) {
cursor.close();
return true;
}

return false;
}

public static void createShortCut(Context context) {
final Intent addIntent = new Intent(
"com.android.launcher.action.INSTALL_SHORTCUT");
final Parcelable icon = Intent.ShortcutIconResource.fromContext(
context, R.drawable.touxiang); // 获取快捷键的图标
addIntent.putExtra("duplicate", false);
final Intent myIntent = new Intent(context, FirstActivity.class);//点击快捷方式要显示的东西
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "快捷方式的名字");// 快捷方式的标题,要和应用的名字一样，为了判断师傅已经创建此快捷方式
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);// 快捷方式的图标
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, myIntent);// 快捷方式的动作
context.sendBroadcast(addIntent);
}
