当我的 fragment 膨胀时，它会根据 android 6.0+ 的要求打开一个对话框以获得 WRITE_EXTERNAL_STORAGE 权限。我已经按照每个教程进行操作，但是在授予或拒绝许可时我的任何操作都不会执行。
我希望应用程序关闭并在权限被拒绝时显示 toast ，这意味着当应用程序重新打开时将再次请求权限。
fragment 开始:
public class SecondFragment extends Fragment {
View myView;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
myView = inflater.inflate(R.layout.second_layout, container, false);
configureImageButton();
((MainActivity) getActivity()).setActionBarTitle("App");
if (ContextCompat.checkSelfPermission(getActivity(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(),
Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
} else {
ActivityCompat.requestPermissions(getActivity(),
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
1);
}
}
onRequestPermissionsResult:
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
switch (requestCode) {
case 1:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Snackbar.make(myView, "Permission Granted.", Snackbar.LENGTH_LONG).show();
} else if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_DENIED) {
Toast.makeText(getActivity(), "Reopen app and allow permission.", Toast.LENGTH_LONG).show();
getActivity().finish();
}
}
}
应用会授予/拒绝权限，但会忽略 toast 或 snackbar。 所有建议表示赞赏。谢谢!
最佳答案
fragment 内部有一些变化 请像下面这样尝试
private void checkLocationPermission() {
if (ContextCompat.checkSelfPermission(this.mContext, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (shouldShowRequestPermissionRationale(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
//Prompt the user once explanation has been shown
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
MY_PERMISSIONS_REQUEST_CODE);
} else {
// No explanation needed, we can request the permission.
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
MY_PERMISSIONS_REQUEST_CODE);
}
}
}
在你的情况下 MY_PERMISSIONS_REQUEST_CODE = 1
