我有以下代码来设置EditText标题栏（主流程）的值，但它失败并且没有分配任何值。

你能告诉我怎么setText做吗？

以下是我的代码（我的主活动）

@SuppressWarnings("deprecation")
public class MainActivity extends Activity
{
    private AsyncTask <Void , Void, Void> mRegisterTask ;
    private String userid;
    private String orderid;
    ...


    View inflatedView = getLayoutInflater().inflate(R.layout.activity_main, null);
    final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
    userid = "99999"; 
    s.setText(userid);

这样做

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
                EditText s = (EditText) findViewById(R.id.textView2);
                userid = "99999"; 
                s.setText(userid);

                // or

               View inflatedView = getLayoutInflater().inflate(R.layout.activity_main, null);
               final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
               userid = "99999"; 
               s.setText(userid);
               setContentView(inflatedView);

    }

您也可以简单地使用它：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    EditText s = (EditText) findViewById(R.id.textView2);
    userid = "99999"; 
    s.setText(userid);

}
