无法从TextView上的对话框设置数据

Question

我从Dialog读取数据，但我无法在TextView上设置该数据。

我做错了什么？

Answer 1

// We can't imagine what you are doing wrong, without seeing your source code.  
TextView facePalm = (TextView)findViewById(R.id.youtextview);
facePalm.setText("Like Octavian Damiean said you should improve your question.");

Answer 2

自定义对话框时，应该这样做：

LayoutInflater inflater = LayoutInflater.from(this);
final View layoutview = inflater.inflate(R.layout.rootview, null);
final TextView title=(TextView) layoutview.findViewById(R.id.text);
