I can't move a button inside a frame layout

Question

I have tried to move the button using graphical interface and android:layout_alignParentLeft in XML file, anyway it does not work. My Android Studio version is 2.2.3. Have you ever had this problem?

Answer 1

You need RelativeLayout or other simlilar layout as parent container because FrameLayout just draw the views one over another plus you should check the properties section to see the attibute properties that you can apply on your layout.
