问题 I am making a vertical EditText for traditional Mongolian. I have successfully implemented it by embedding a slightly modified EditText inside of a rotated ViewGroup . I need to create a completely custom context menu because the system one does not support vertical text and is also not rotated when the ViewGroup is rotated.

问题 I have a ListView where each row has an EditText control. I want to add a TextChangedListener to each row; one that contains extra data which says which row the EditText was in. The problem is that as getView gets called, multiple TextWatchers are added; because the convertView already having a TextWatcher (and one that points to a different row).

问题 In the layout you can set the EditText widget to be non-editable via the android:editable attribute . How can I do this in code?

问题 I have an EditText-Field and set an OnFocusChangeListener for it. When it has lost focus, a method is called, which checks the value of the EditText with one in the database. If the return-value of the method is true, a toast is shown and the focus should get back on the EditText again. The focus should always get back on the EditText and the keyboard should show, until the return-value of the method is false. EDIT: I think, I haven't made my real problem perfectly clear yet: No other Item on
