我有一个editText,我希望当用户按下键盘上的空格键时将其清空。 (这里是android的新手=])
UserInput.setOnKeyListener(new EditText.OnKeyListener(){
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if((event.getAction() == KeyEvent.ACTION_DOWN) && (event.getKeyCode() == event.KEYCODE_SPACE)) {
UserInput.setText("");
}
return false;
}
});
任何帮助将不胜感激! =)

当用户单击空格按钮定义您自己的操作时,尝试这对您肯定有用...
youredittext.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// If the event is a key-down event on the "enter" button
if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
(keyCode == KeyEvent.KEYCODE_SPACE)) {
// Perform action on key press
youredittext.setText("");
Toast.makeText(getApplicationContext(), youredittext.getText(), Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});
