requestPermission:如何等待授权?

把你的逻辑放在它自己的函数中,在 onCreate() .

private void doStuff() {
    //whatever
}

onCreate()

@Override
public void onCreate(Bundle savedInstanceState) {
    //...
    if (checkSelfPermissions(/*whatever*/) {
        doStuff();
    } else {
        requestPermissions(/*whatever*/);
    }

    //nothing dependent on runtime permissions after this point
}

然后重写 onRequestPermissionsResult()

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if (requestCode == /*whatever you set in requestPermissions()*/) {
        if (!Arrays.asList(grantResults).contains(PackageManager.PERMISSION_DENIED)) {
            //all permissions have been granted
            doStuff(); //call your dependent logic
        }
    }
}
