edittext of onKeyListener whether to perform twice

            
edit2.setOnKeyListener (new OnKeyListener () {
public boolean onKey (View v, int keyCode, KeyEvent event) {

if (keyCode! = 66) / / 66 is the Enter key
{
return false;
}

edittext2 = edit2.getText () toString ();.
textview.setText (edittext2);
}
});
Thus, textview will perform twice, setText twice, is not because of the original carriage will run once or twice
executed this onKey

Other places call textview.setText () instead. Interrupted point look
