What's the little widget with three dots? How can I add it to my app?
解决方案
This is not a widget at all. It is an ImageButton
(borderless in style) using the overflow Icon that includes a PopupMenu
For documentation tutorial visits http://developer.android.com/guide/topics/ui/menus.html#PopupMenu
This refers to a nice code snippet from the link above:
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_overflow_holo_dark"
android:contentDescription="@string/descr_overflow_button"
android:onClick="showPopup" />
Then use to show popup:
public void showPopup(View v) {
PopupMenu popup = new PopupMenu(this, v);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.actions, popup.getMenu());
popup.show();
}
3-Dots button is available among Assets in Android Studio:
Right click on res
-> New -> Vector Assets -> Asset Type = Clip Art
-> Click on the button next to Clip Art: label -> Search for more vert
