EditText动态转换只读/编辑状态

 1 public class MyActivity extends Activity
 2 {
 3     private KeyListener listener;
 4     private EditText editText;
 5 
 6     public void onCreate(...)
 7     {
 8         editText = ... // Get EditText from somewhere
 9         listener = editText.getKeyListener(); // Save the default KeyListener!!!
10         editText.setKeyListener(null); // Disable input
11     }
12 
13     // When you click your button, restore the default KeyListener
14     public void buttonClickHandler(...)
15     {
16         editText.setKeyListener(listener);
17     }
18 }

 

Basically, you first save the EditText's default KeyListener before you call setKeyListener(null). Then, when you click your button, you call setKeyListener again, passing the default listener you previously saved.
