问题 i am trying to add some social images in my app about me screen but i am facing a problem of giving equal spaces between imageviews. my images looks like this: but i want to make them look like this: my code: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout1" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/about_screen" > <LinearLayout android

Instead, getScaleX() and getScaleY() alsways return 1.0 for me whether the image is scaled down or not. You can see my XML here: <?xml version="1.0"

I just can't seem to get the buttons to scale. They look great on the Tab...but on
