如何设置侦听器？

我想我需要一个监听器，但不能设置它。在下面的代码中，时间对话框和日期对话框都起作用。随后出现小对话框，我选择一个日期/时间，然后选择我有我的日期。但我无法使文本输入工作。我已经尝试了几次这样的代码从一个示例程序迭代： bnBodyEntered = true; bodyDialog = new TextInputDialog（this）; bodyDialog.setText（“body”）; 这段代码显示了带有字母滚轮的文本对话框，但程序已经过去了，当我输入几个字母并且没有选择任何事情时。因为我没有成立听众。所以我补充说（如注） bodyDialog.setOnDismissListener（textSetListener）; 使用几个“setOn ---- Listener”值，它或者仍然运行过去，或者我得到各种编译错误。如何设置侦听器？

这是为我的WIMMOne手表，所以版本7，没有虚拟键盘。它需要是一个对话框。

（注：我删除了发布前的注释代码采空区 - 可能更多的东西，所以如果它没有因为 - 对不起。）

感谢，克拉克

多小时后猜测和错误，这工作。

我不认为“Return bodyDialog”会做任何事情;我最终直接从侦听器更新EditText字段。 “arg0”具有对话的长名称 - 没有用处。但你有它防止编译错误。

对于没有虚拟键盘且需要使用文本输入对话框的WIMMOne，这可能是独一无二的。

protected Dialog onCreateDialog(int id) 
    { 
switch (id) 
     . . . . 
     case BODY_DIALOG_ID: 
      bodyDialog = new TextInputDialog(this); 
      bodyDialog.setOnDismissListener(textSetListener); 
      return bodyDialog; 


private OnDismissListener textSetListener = new OnDismissListener() 
{ 
@Override 
public void onDismiss(DialogInterface arg0) 
    { 
    Log.d("RemindEA","101S BodyLisner" + arg0); 
    String strxx = bodyDialog.getText(); 
    mBodyText.setText(strxx); 

    } 
};
