android - How to create exactly square buttons that fill in width of screen -

i've activity fill buttons dynamically base on tablelayout , tablerow this:

    private tablelayout buttontablelayout;     //-----     (int row = 0; row < buttontablelayout.getchildcount(); ++row)         ((tablerow) buttontablelayout.getchildat(row)).removeallviews();      layoutinflater inflater = (layoutinflater) getsystemservice(context.layout_inflater_service);      (int row = 0; row < 5; row++) {         tablerow currenttablerow = gettablerow(row);          (int column = 0; column < 5; column++) {                 button newguessbutton = (button) inflater.inflate(r.layout.my_button, currenttablerow, false);                 newguessbutton.settext(string.valueof((row * 5) + column + 1));                 currenttablerow.addview(newguessbutton);             }          }     }     //----     private tablerow gettablerow(int row) {         return (tablerow) buttontablelayout.getchildat(row);     } 

i want make 5*5 list of buttons 1:all of them has same width , height , 2: make them fill of screen. in code have layout named my_button, :

<button xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/newbutton" android:layout_width="60dp" android:layout_height="60dp" android:background="@drawable/button_style"></button> 

or

<button xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/newbutton" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:background="@drawable/button_style"></button> 

and results is:

i have change gravity doesn't works.is there way make them square , fill width of screen.

you should sub-class button view , override below function:

public class squarebutton extends button { public squarebutton(context context) {     super(context); }  public squarebutton(context context, attributeset attrs) {     super(context, attrs); }  public squarebutton(context context, attributeset attrs, int defstyleattr) {     super(context, attrs, defstyleattr); }  public squarebutton(context context, attributeset attrs, int defstyleattr, int defstyleres) {     super(context, attrs, defstyleattr, defstyleres); }  @override public void onmeasure(int widthmeasurespec, int heightmeasurespec) {     super.onmeasure(widthmeasurespec, widthmeasurespec);     int width = measurespec.getsize(widthmeasurespec);     int height = measurespec.getsize(heightmeasurespec);     int size = width > height ? height : width;     setmeasureddimension(size, size); // make square  } } 

edit: ok, need customize button above. then, instead of using default button, can use above squarebutton.
