Total Logic was taken from Android Studio. Link::https://developer.android.com/guide/topics/ui/dialogs.html

Step 1:

public class MCListDemo extends DialogFragment{

List<String> selectedList;

private String[] colors;

@Override

public Dialog onCreateDialog(Bundle savedInstanceState) {

colors = new String[]{"Red", "Green", "Blue"};

selectedList = new ArrayList<>();

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

builder.setTitle("Select your favourite")

.setMultiChoiceItems(colors, null, new DialogInterface.OnMultiChoiceClickListener() {

@Override

public void onClick(DialogInterface dialog, int which, boolean isChecked) {

if(isChecked){

selectedList.add(colors[which]);

}else {

selectedList.remove(which);

}

}

})

.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

Toast.makeText(getActivity(), "Select List is ::"+selectedList, Toast.LENGTH_SHORT).show();

}

})

.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

Toast.makeText(getActivity(), "Bye", Toast.LENGTH_SHORT).show();

}

});

return builder.create();

}

}

Step 2:

public class AddingMCList extends AppCompatActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_adding_mclist);

}

public void meth(View view) {

DialogFragment dialogFragment = new MCListDemo();

dialogFragment.show(getFragmentManager(),"mcdemo");

}

}

Step 3:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:id="@+id/activity_adding_mclist"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="mycompany.com.myapplication.AddingMCList">

<Button

android:text="Button"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_centerVertical="true"

android:layout_centerHorizontal="true"

android:id="@+id/mcListDialogfragment"

tools:text="MulitpleChoiseListDialog"

android:onClick="meth" />

</RelativeLayout>
