How can I customize permission dialog in Android?

Question

Suppose I request a permission at runtime like the following:

ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            MY_PERMISSIONS_REQUEST_READ_CONTACTS);

Android system creates a popup dialog to request permission. How can I define a custom layout for that dialog?

Solution 1

The short answer is, you can't.

As android documentation puts:

When your app calls requestPermissions(), the system shows a standard dialog box to the user. Your app cannot configure or alter that dialog box. If you need to provide any information or explanation to the user, you should do that before you call requestPermissions(), as described in "Explain why the app needs permissions".

So, there is no way to define a custom layout for the permission dialog for now.

You can find more detailed information here: http://developer.android.com/training/permissions/requesting.html

Solution 2

I have create custom dialog for permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
   if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, Manifest.permission.READ_EXTERNAL_STORAGE)) {
       AlertDialog.Builder alertBuilder = new AlertDialog.Builder(context);
       alertBuilder.setCancelable(true);
       alertBuilder.setTitle("Permission necessary");
       alertBuilder.setMessage("External storage permission is necessary");
       alertBuilder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {

       @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
       public void onClick(DialogInterface dialog, int which) {
           ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);}});

       AlertDialog alert = alertBuilder.create();
       alert.show();
   } else { 
          ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);}
    return false;} 
 else { 
     return true;
}

Hope this will help you :)

"android... allows you to add some text to that dialog explaining the user why you are requesting that permission" -- not that I am aware of.

@CommonsWare i thought the developer could explain the rationale of using that permission is that wrong? or just android shows its default explanation about that permission?

You can find out, via shouldShowPermissionRequestRationale(), whether you might want to show an explanation. However, you have to do that in your own UI. You cannot add prose to the system dialog for that.

Looks like this just create a new dialogue that when clicked yes, will trigger the system permission dialogue, it does not change the actual permission dialog in Android. No different than calling ActivityCompat.requestPermissions... directly

@BabyishTank : You can not customize system dialog. It's just to create a customize dialog with your own custom message. You can directly call with system permission dialogue.
