I Have a BaseAdapter with a List of all requires permissions for use correctly the app.
I need to, after onClick in one of them, request the permission and check if is granted or not.
For request, I am using
ActivityCompat.requestPermissions
but I do not know how to get the results.
Is it possible to call O
nRequestpermissionsResultCallback
to know the answer of the user?
How can I do it?

so first i implement in the Adapter implements ActivityCompat.OnRequestPermissionsResultCallback then it require one Overide method
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
// it is not work here onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == storagePermission) {
// getPosts(false);
if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {
Toast.makeText(context.getApplicationContext(), "Please allow permission to Continue", Toast.LENGTH_SHORT).show();
}
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(context.getApplicationContext(), " Permissions Granted Succecfully", Toast.LENGTH_SHORT).show();
//here i load my method that i want to run
}
}
}
now problem is this onRequestPermissionsResult is not call from adapter instead adapter triger onRequestPermissionsResult of the mainActivity Attach with the Adapter
so in main Activity i create this and run onRequestPermissionsResult of adapter by passing adapterPosts.onRequestPermissionsResult(requestCode,permissions,grantResults);
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == storagePermission) {
// getPosts(false);
if (grantResults[0] != PackageManager.PERMISSION_GRANTED) {
//permission not granted
}
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
//permission granted
adapterPosts.onRequestPermissionsResult(requestCode,permissions,grantResults);
//loadImageIntent();
}
}
}

I solved this from custom class. My custom class is derived from AppCompatActivity
. Also you need to pass Activity context to your custom class and do whatever you need with it.
public bool AreStorageAndCamPermissionsGranted(Activity context)
{
if (Build.VERSION.SdkInt >= Build.VERSION_CODES.M)
if (
context.CheckSelfPermission(Manifest.Permission.Camera)!= Android.Content.PM.Permission.Granted
|| context.CheckSelfPermission(Manifest.Permission.ReadExternalStorage) != Android.Content.PM.Permission.Granted
|| context.CheckSelfPermission(Manifest.Permission.WriteExternalStorage) != Android.Content.PM.Permission.Granted)
{
ActivityCompat.RequestPermissions(context, new String[]
{
Manifest.Permission.Camera,
Manifest.Permission.ReadExternalStorage,
Manifest.Permission.WriteExternalStorage,
}, REQUEST_PERMISSION_CODE);
}
return true;
}

I have a same problem in RecylclerView.Adapter and I use this section in permission request method
private void requestCallPhonePerm() {
if (ContextCompat.checkSelfPermission(context,
Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED) {
onItemCallListener.itemCallPhone(itemPhones);
ActivityCompat.requestPermissions((Activity)context,
new String[]{Manifest.permission.CALL_PHONE},
MY_PERMISSIONS_REQUEST_CALL_PHONE);
} else {
((MainActivity)context).callPhone(itemPhones);
}
}
It's important to use (Activity)context in "requestPermissions" method to be invoked callback in container activity of your adapter
And in my MainActivity that contain recycler I use overrided request permission result normally.
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch(requestCode){
case MY_PERMISSIONS_REQUEST_READ_CONTACTS:
if(grantResults.length>0
&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
new LoadContacts().execute();
}
break;
case MY_PERMISSIONS_REQUEST_CALL_PHONE:
if(grantResults.length>0&&grantResults[0]==PackageManager.PERMISSION_GRANTED){
callPhone(phones);
}else{
}
}
}

In your adapter class
class Adapter extends RecyclerView.Adapter<Your adapter.MyViewHolder> implements ActivityCompat.OnRequestPermissionsResultCallback{`//enter code here`}
It will override the onRequestPermissionsResult

To check the permission (in this example it's a permission to use the camera):
int permissionCheck = ContextCompat.checkSelfPermission(this,
Manifest.permission.CAMERA);
if (permissionCheck == PackageManager.PERMISSION_DENIED) {
// permission is not granted yet, let's ask for it
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CAMERA},
MyActivity.cameraRequestCode);
} else {
// permission is already granted
}
If ActivityCompat.requestPermissions is run, then a dialogue appears for the user, after which you can catch the result by overriding the Activity's onRequestPermissionsResult like this:
@Override
public void onRequestPermissionsResult(int requestCode,
String permissions[], int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case MyActivity.cameraRequestCode: {
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// action when permission granted
} else {
// action when permission denied
}
return;
}
}
}
MyActivity.cameraRequestCode is a static int, can be any unique int value.
