The Activity class simply toggles the visibility of the two buttons when any of the buttons are clicked. The one thats selected is an ImageView, below that theres a TextView and. I found that I need a SurfaceView or the problem does not occur (for example, change it to TextView and the problem disappears). On the left side you can see a hierarchy of the views that are used in the UI.

I was able to reduce the code to the following layout that exhibits the problem on an Android 4.0.3 emulator but not a Galaxy Tab. Here are the examples of the java api taken from open source projects. T is located in the same RelativeLayout but is not related to the buttons (their locations are independent and non-overlapping).Įdit: In case some Android dev wants to track this down… Now follow the below steps to create this application. On the second click, the dimensions are 200sp. After the first click, the dimensions become 100sp.

I randomly discovered that, for a certain TextView t, the following code causes the buttons to become visible: t.setText(t.getText()) Meaning, for, before that first click, the TextView length and height are 50 sp and 50sp. The button shows OK on a Galaxy Tab 10.1' but not in a smaller tablet (not sure which model), nor on an Android 4.0 emulator. I am trying to show a pair of hidden buttons (using setVisibility(View.VISIBLE), within a RelativeLayout), but it doesn't always work.
