Question

我想我需要一个听众，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有效。滚动的小对话框出现，我选择日期/时间，然后选择，我有我的约会。但我不能让文本输入工作。我从一个示例程序中尝试了几次这段代码的迭代，该程序具有： bnBodyEntered = true; bodyDialog = new TextInputDialog（this）; bodyDialog.setText（ “身”）; 这段代码显示了带有字母滚轮的文本对话框，但程序已经过了它，当我输入几个字母并且没有选择任何事情。这使得因为我没有建立一个听众。所以我补充说（如上所述） bodyDialog.setOnDismissListener（textSetListener）; 使用几个“setOn ---- Listener”值并且它仍然运行过去，或者我得到各种编译错误。

这是我的WIMMOne手表，因此版本7并没有虚拟键盘。它需要是一个对话框。

（注意：我在发布之前删除了评论代码的大部分内容 - 可能还有更多内容，所以如果它自那以后就没有了 - 抱歉。）

谢谢，Clark

经过数小时的猜测和错误，这很有效。

我不认为“Return bodyDialog”会做任何事情;我最终直接从侦听器更新了EditText字段。 “arg0”有一个很长的对话名称 - 没有用。但是你有它可以防止编译错误。

这可能是WIMMOne独有的，它没有虚拟键盘，你需要使用它们的文本输入对话框。

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);

   }
 };

如何设置监听器？
