问题 I have a grid view with various image views within it, and I want these images to disappear when touched. How can I do this?

问题 Pretty much I have a Textview that is acting as a display for asterisks when a user clicks a pin pad of Buttons I made. The buttons have their text centered, but it seems when I append something to the Textview text property the number 2 pin's layout changes to center at the bottom instead of the dead center. This is part part of the xml: <!-- PIN text --> <TableLayout> <TableRow android:id="@+id/btn_row1" android:gravity="center" android:layout_marginTop="6dip"> <!-- password text-->
