DialogFragment
Step 1 : create ListDialog class.
Step 2 : create AddingListToDialogActivity .
Step 4 : create layout file like activity_adding_list_to_dialog.xml
Step 3: run and watch the output & all the best...
Logic had been taken from android studio.
Step 1:
public class ListDialog extends DialogFragment {
private String[] colors ;
private int[] a = new int[]{1,2,3};
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
colors = new String[]{"Red", "Green", "Blue"};
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Select a color");
builder.setItems(colors, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(getActivity(), "Selected color is ::"+colors[which], Toast.LENGTH_SHORT).show();
}
});
return builder.create();
}
}
Step 2:
public class AddingListToDialogActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_adding_list_to_dialog);
Button button = (Button) findViewById(R.id.select_color_bt);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DialogFragment fragment = new ListDialog();
fragment.show(getFragmentManager(),"tag");
}
});
}
}
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_list_to_dialog"
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.AddingListToDialogActivity">
<Button
android:text="Button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="192dp"
android:id="@+id/select_color_bt"
tools:text="Select a color"/>
</RelativeLayout>
Output:
