Java method for android:layout_gravity

Question

I would like to know if is there a way to call android:layout_gravity property from a Java method. I didn\'t found any method in Android documentation to do it.

Answer 1

Watchout! This wouldn't work with LinearLayout though. Because LinearLayout.LayoutParams(...) constructor is different from FrameLayout.LayoutParams(...) constructor. The third parameter is not gravity but weight.

     LinearLayout.LayoutParams(int width, int height, float weight)

as opposed to

     FrameLayout.LayoutParams(int width, int height, int gravity)

and this call, despite not producing compiler error is actually wrong:

lparams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.LEFT);
