I have a Tabbed Activity, In Tab2.Java, I want to show a Custom Dialog on a Button Click. (For Custom Dialog, I have a separate xml file named: dg_selct.xml.) Code:
public class Tab2 extends Fragment {
Button btn;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.tab2, container, false);
btn=(Button)v.findViewById(R.id.button2);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final AlertDialog.Builder dialog = new AlertDialog.Builder(getContext());
View bView = getLayoutInflater().inflate(R.layout.dg_selct,null);
dialog.setView(bView);
AlertDialog customDialog = dialog.create();
customDialog.setTitle("Search");
customDialog.show();
}
});
Here is dg_selct.xml:

Also, When I use final AlertDialog.Builder dialog = new AlertDialog.Builder(Tab2.this); instead of final AlertDialog.Builder dialog = new AlertDialog.Builder(getContext()); , Compiler gives an error: "Builder (android.Content.context) in Builder cannot be applied to com.abc.Tab2"
dg_select.xml has some CheckBoxes and a TextView. But When Dialog is shown, I only see the title as mentioned in above Code. How do I inflate the dg_selct.xml in this Dialog?
try this use Dialog instead of AlertDialog
Dialog dialog = new Dialog(getActivity());
dialog.setContentView(R.layout.dg_selct);
// to bind your control from dialog like this
final TextView textView= (TextView) dialog.findViewById(R.id.YourTextBiew);
final CheckBox checkBox= (CheckBox) dialog.findViewById(R.id.YourCheckBox);
final Button btnShow = (Button) findViewById(R.id.btnShow);
textView.setText("PREM");
dialog.setTitle("Search");
dialog.show();
UPDATE
change Your
RelativeLayouthight & width tomatch_parentORwrap_contentlike below code
<RelativeLayout
android:id="@+id/relativeLayout2"
android:layout_width="match_parent"
android:layout_height="match_parent">
