android动态添加自定义TextView后如何在Dialog上获得的值更新某一个TextView的内容,我是新手，请大神指点，谢谢！！！

Answer 1

public class MainActivity extends Activity { private int index; private TextView mTextView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mTextView = new TextView(this); setContentView(mTextView); new DataThread().start(); } private String getWebData() { return String.valueOf(++index); } private Handler mHandler = new Handler() { public void handleMessage(android.os.Message msg) { mTextView.setText((String)msg.obj); }; }; private class DataThread extends Thread { @Override public void run() { for(int i = 0; i < 4; i++) { try { Thread.sleep(1000); } catch (InterruptedException e) { } final String data = getWebData(); // 只能在主线程中修改ui控件 mHandler.sendMessage(mHandler.obtainMessage(0, data)); } } }}追问

可在dialog中是可以实现的，但：更新的数据在最后一个view中显示.
