代碼： HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(URL);
try{
HttpResponse response = httpClient.execute(httpPost);
String jsonResult = convertStreamToString((response.getEntity().getContent())).toString();
JSONObject obj = (JSONObject) new JSONTokener(jsonResult).nextValue();
JSONObject obj2 = obj.getJSONObject("GetRingkasObjekPajak_SingleResult");
String nameWP = obj2.getString("NM_WP");
TextView tv = (TextView)findViewById(R.id.dummy_text_three);
tv.setText(jsonResult);
}catch (MalformedURLException e) {
// URL is invalid
TextView tv = (TextView) findViewById(R.id.dummy_text_three);
tv.setText("url invalid");
} catch (SocketTimeoutException e) {
// data retrieval or connection timed out
TextView tv = (TextView) findViewById(R.id.dummy_text_three);
tv.setText("RTO");
} catch (IOException e) {
// could not read response body
// (could not create input stream)
TextView tv = (TextView) findViewById(R.id.dummy_text_three);
tv.setText("couldnt read response");
} catch (JSONException e) {
// response body is no valid JSON string
TextView tv = (TextView) findViewById(R.id.dummy_text_three);
tv.setText("json response fail");
}catch (Exception e) {
// TODO: handle exception
TextView tv = (TextView) findViewById(R.id.dummy_text_three);
tv.setText(e.toString());
}我已經添加了權限。然后出現了NetworkOnMainThreadException。

這有一個異步任務的例子，你可以看看。
private class YourAsyncTaskClass extends AsyncTask {
@Override
protected String doInBackground(String... params) {
//your http network call here.
return null;
}
@Override
protected void onPostExecute(String result) {
//update your ui here
}
@Override
protected void onPreExecute() {
//do any code before exec
}
@Override
protected void onProgressUpdate(Void... values) {
//If you want to update a progress bar ..do it here
}
}然后調用此類的時候：
new YourAsyncTaskClass().execute();
