Alert dialog is not showing in full screen

Question

My "no inte.net" alert dialog is not showing in full screen and also to mention that my button after i click not refreshing just disappear..what should i do to change it to open in full screen, i also tried with setContentView too, but it not worked..

This is my code..

Class file:

public class NetworkChangeListener extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(!Common.isConnectedToInternet(context)){
            AlertDialog.Builder builder =  new AlertDialog.Builder(context);
            View view = LayoutInflater.from(context).inflate(R.layout.alert_dialog,null);
            builder.setView(view);

            AppCompatButton btnRetry = view.findViewById(R.id.btnRetry);

            AlertDialog dialog = builder.create();
            dialog.show();
            dialog.setCancelable(false);
            dialog.getWindow().setLayout(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);

            btnRetry.setOnClickListener(view1 -> {
                dialog.dismiss();
                onReceive(context,intent);
            });
        }
    }
}

set minWidth and minHeight of 800dp/1000dp to RelativeLayout of your dialog layout file.

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#f7f7f7"
    android:id="@+id/nointernet"
    minWidth="1000dp"
    minHeight="1000dp">
       // rest of the views.
    </RelativeLayout>
