[Android Pro] 创建快捷方式,删除快捷方式,查询是否存在快捷方式

1: 创建快捷方式

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

private static void createShortcut(Context cxt, String shortcutName, int shortcutIconRes,
String className, boolean duplicate, boolean laucherCategory) { Intent intent = getShortCutIntent(cxt, cxt.getPackageName(), className, shortcutName,
laucherCategory);
int iconsize = cxt.getResources().getDimensionPixelSize(Res.dimen.app_icon_size);
BitmapDrawable icon = (BitmapDrawable) cxt.getResources().getDrawable(shortcutIconRes);
Bitmap bmp = ImageUtils.scaleTo(icon.getBitmap(), iconsize, iconsize, false);
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bmp);
intent.putExtra(EXTRA_SHORTCUT_DUPLICATE, duplicate); // Now, notify the launcher to create the shortcut
cxt.sendBroadcast(intent);
}
private static Intent getShortCutIntent(Context cxt, String pkgName, String className,
String shortcutName, boolean laucherCategory) {
// Prepare the intents for shortcut
Intent shortcutIntent = new Intent(Intent.ACTION_VIEW);
shortcutIntent.setClassName(pkgName, className);
shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shortcutIntent.putExtra(Constants.EXTRA_FROM_KEY, Constants.EXTRA_FROM_VALUE_SHORTCUT);
if (laucherCategory) {
shortcutIntent.addCategory(Intent.CATEGORY_LAUNCHER);
shortcutIntent.setAction(Intent.ACTION_MAIN);
} Intent intent = new Intent(ACTION_INSTALL_SHORTCUT);
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
return intent;
}

2:删除快捷方式(MIUI系统不支持):

需要权限:<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

public static void removeShortcut(Context cxt, String shortcutName, String className,
boolean removeAll) {
// Prepare the intents for shortcut
Intent shortcutIntent = new Intent(Intent.ACTION_VIEW);
shortcutIntent.setClassName(cxt, className); Intent intent = new Intent(ACTION_UNINSTALL_SHORTCUT);
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
intent.putExtra(EXTRA_SHORTCUT_DUPLICATE, removeAll); // Now, notify the launcher to remove the shortcut
cxt.sendBroadcast(intent);
}

3:查询快捷方式是否存在(三方rom大部分查询失败,cursor为null)

需要权限:<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

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

private boolean hasShortcut()
{
boolean isInstallShortcut = false;
final ContentResolver cr = activity.getContentResolver();
final String AUTHORITY ="com.android.launcher.settings";
final Uri CONTENT_URI = Uri.parse("content://" +AUTHORITY + "/favorites?notify=true");
Cursor c = cr.query(CONTENT_URI,new String[] {"title","iconResource" },"title=?",
new String[] {getString(R.string.app_name).trim()}, null);
if(c!=null && c.getCount()>0){
//String title = c.getString(c.getColumnIndexOrThrow("title"));
isInstallShortcut = true ;
}
return isInstallShortcut ;
}
