将结果更新到AlertDialog Android的TextView

Question

当我尝试将程序的结果设置为对话框中的textView时，应用程序强制关闭。我通过链接一个带有textview的xml来创建对话框，这是我试图更新的文本视图。

AlertDialog.Builder alert = new AlertDialog.Builder(this); 
    LayoutInflater factory = LayoutInflater.from(this);        
    resultOne=(TextView)findViewById(R.id.resultOne); //resultone is a textview in xml dialog

    resultOne.setText("hello");  //this code is making the app close

    final View textEntryView = factory.inflate(R.layout.dialog, null);
    alert.setView(textEntryView);
    alert.show();

Answer 1

更改订单，以便在充气后访问View的孩子。您还需要使用textEntryView来查找ID，如下所示：

LayoutInflater factory = LayoutInflater.from(this);        
final View textEntryView = factory.inflate(R.layout.dialog, null);

resultOne=(TextView)textEntryView.findViewById(R.id.resultOne); //resultone is a textview in xml dialog

resultOne.setText("hello");
alert.setView(textEntryView);

alert.show();
