Android-修复图标的位置

Question

I have a two RelativeLayouts which each contains an ImageView and a TextView . On clicking on a TextView , the size of the TextView increases and the size of the other Textview decreases. However, the position of the ImageView also changes.I want the Image to be fixed irrespective of the size of the textview . What changes should be made?

Answer 1

Try by setting your 2 RelativeLayout s android:layout_width as 0dp.

When Linearlayout contains many views inside and set layout_weight as 1 layout_height or layout_width = 0dp is used, in order to take equal space for both views.
