我想讓我的應(yīng)用程序在應(yīng)用程序繼續(xù)之前等待用戶授予權(quán)限。我搜索了有關(guān)它的其他線程，發(fā)現(xiàn)常見的方法是使用onRequestPermissionResult. 現(xiàn)在我對(duì)如何設(shè)置它一無所知：我是將我的程序代碼放入onRequestPermissionResult除了請(qǐng)求本身還是我需要如何設(shè)置它，以便用戶被要求然后應(yīng)用程序繼續(xù)？這是我的代碼：if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 123); } else { progressBar.setVisibility(View.VISIBLE); GPSTracker gt = new GPSTracker(getActivity().getApplicationContext()); Location location = gt.getLocation(); if (location == null) { Toast.makeText(getActivity(), "No location found.", Toast.LENGTH_LONG).show(); } else { lat = location.getLatitude(); lon = location.getLongitude(); } new GetContacts().execute(); }} else { progressBar.setVisibility(View.VISIBLE); GPSTracker gt = new GPSTracker(getActivity().getApplicationContext()); Location location = gt.getLocation(); if (location == null) { Toast.makeText(getActivity(), "No location found.", Toast.LENGTH_LONG).show(); } else { lat = location.getLatitude(); lon = location.getLongitude(); } new GetContacts().execute();}和請(qǐng)求結(jié)果：@Overridepublic void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case 123: { // If request is cancelled, the result arrays are empty if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { progressBar.setVisibility(View.VISIBLE); GPSTracker gt = new GPSTracker(getActivity().getApplicationContext()); Location location = gt.getLocation();

就像評(píng)論中提到的 Martin Zeitler 一樣，您必須為 Marshmallow 上方和下方的 API 做好準(zhǔn)備，例如：
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if(ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(getActivity(), new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, 123);
} else {
//GPS method
}
} else {
//GPS method
}
就像你在 onRequestResult 的問題中提到的一樣：
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
switch (requestCode) {
case 123: {
// If request is cancelled, the result arrays are empty
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//GPS method
} else {
// Toast for user
}
return;
}
}
}
