Android：如何在android棒棒糖中打開設置屏幕

-1

我想通過android 5.0中的應用程序打開設置屏幕，即棒棒糖。當我下提到的代碼中使用，應用程序崩潰：Android：如何在android棒棒糖中打開設置屏幕

Intent mSettingIntent = new Intent(Settings.ACTION_SETTINGS); 
mSettingIntent.addCategory(Intent.CATEGORY_LAUNCHER); 
startActivity(mSettingIntent);

的logcat：

把你的Logcat輸出 – 2015-01-21 04:36:18

不需要這行 - mSettingIntent.addCategory（Intent.CATEGORY_LAUNCHER）; – 2016-05-16 16:26:04

試試這個，

startActivityForResult(new Intent(android.provider.Settings.ACTION_SETTINGS), 0);

如果你只是想打開「設置」應用程序，然後嘗試folling ：

startActivity(new Intent(Settings.ACTION_SETTINGS));
