您无法在doInBackground方法中触摸与UI相关的任何内容，因此这就是问题所在：
TextView textView=(TextView) findViewById(R.id.textView1);
textView.setText(first_array.getJSONObject(1).getString("Starters"));
将此项移至onPostExecute。
答案 1 :(得分：0)
你不能在doInbackground（）中做与UI相关的东西。所以请从doInBackground（）中删除以下行并将其放在onPostExecute（）中。
TextView textView=(TextView) findViewById(R.id.textView1);
textView.setText(first_array.getJSONObject(1).getString("Starters"));
答案 2 :(得分：0)
首先你必须找到这个：
TextView timedisplay=(TextView) findViewById(R.id.RestaurantTimeID);
ListView yourListView = (ListView) findViewById(R.id.listViewID);
，而不是在MainActivity.class中 onPostExecute（）方法.....
并且在 RestaurantDesc.java 中找到 TextView onCreate（）方法的ID ...
并更新此
textView.setText(first_array.getJSONObject(1).getString("Starters"));
在 onPostExecute（）方法中; ...
你的第一个数组以i = 0开始，所以改变所有
textView.setText(first_array.getJSONObject(0).getString("Starters"));
textView.setText(first_array.getJSONObject(1).getString("Starters"));
textView.setText(first_array.getJSONObject(2).getString("Starters"));
答案 3 :(得分：0)
正如对方所说，你不能在doInBackground方法中触及与UI相关的任何内容。
您可以使用onProgressUpdate方法更新UI。
http://developer.android.com/reference/android/os/AsyncTask.html
通常，我把所有功能
protected void onProgressUpdate(Integer... progress) {
switch (progress[0]) {
case 1: {
TextView textView=(TextView) findViewById(R.id.textView1);
textView.setText(first_array.getJSONObject(1).getString("Starters"));
.....
break;
}
case 2: {
......
break;
}
case 3: {
}
default: {
......
break;
}
}
你可以从doInBackground方法中以这种方式调用它
publishProgress(number of the case that you want);
