PROSAGA码农传奇-Andriod-文本视图不显示任何文本

<div class =“post-text”itemprop =“text”>
  
    这部分代码：
     <code>
 txtView.setText(stringHandler.getString());
 </code>
  
  
    应该在线程完成后放入。
  
   <pre>
 <code>
 thread.run(); <------ Start running thread in background

TextView txtView = (TextView)this.findViewById(R.id.textView1);
        txtView.setText(stringHandler.getString());
        // the textView was set without knowing whether the Thread is finished or not.
        // thus, textView is shown as empty, because stringHandler.getString() still has empty string

</code>
 </pre>
  
    我的建议是你在里面实现它
     <code>
 asyncTask
 </code>
    ，以便您可以在其中设置文本
     <code>
 onPostExecute()
 </code>
  
  
    祝你好运^^

这是AsyncTask的一些例子
  
   <pre>
 <code>
 private class StringSet extends AsyncTask <Void,Void,Void> {

@Override 
protected void doInBackground(Void... params) {

try {
         stringHandler.setString(webRequest());
    } catch (Exception e) {
         stringHandler.setString(e.getMessage());
    }
}

@Override 
protected void onPostExecute(Void... results) {
    txtView.setText(stringHandler.getString());
    }
}

</code>
 </pre>
  
    并替换你的
     <code>
 thread.run()
 </code>
     同
     <code>
 new StringSet().execute();
 </code>
  
</DIV>
