Question

I’m trying to create a FrameLayout programmatically as follows(this view will float on the the bottom center of a LinearLayout):

    FrameLayout bottomFrameLayout = new FrameLayout(context);
    bottomFrameLayout.setLayoutParams(new FrameLayout.LayoutParams(0,LayoutParams.FILL_PARENT,Gravity.CENTER | Gravity.BOTTOM));

Since I set layout_width=0dp, I would like to also set layout_weight to control the width. How can I do that?

Answer 1

You need to use LinearLayout.LayoutParams (int width, int height, float weight) constructor since FrameLayout is child of LinearLayout therefore you are setting params for child in LinearLayout.

Edit:

 FrameLayout bottomFrameLayout = new FrameLayout(context);
 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(0,LayoutParams.FILL_PARENT,mWeight);
 lp.gravity = Gravity.CENTER | Gravity.BOTTOM;
 bottomFrameLayout.setLayoutParams(lp);
