我正在尝试向我的网站发送一些数据。单击按钮时，需要向网站发送数据
但是我在运行程序的时候出现了一些错误
当我点击按钮时，出现“不幸的是应用程序已停止”的消息，然后退出我的应用程序。
public class testInput extends Activity {
Button Setbutton;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.test_input_page);
Setbutton=(Button)findViewById(R.id.setbtn);
Setbutton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
testInput ti=new testInput();
//Create the intent
ti.postData("Sent Data");
});
}
public void postData(String toPost) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://mysite.com/index.php");
//This is the data to send
String MyName = toPost; //any data to send
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
nameValuePairs.add(new BasicNameValuePair("action", MyName));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String response = httpclient.execute(httppost, responseHandler);
//This is the response from a php application
String reverseString = response;
Toast.makeText(this, "response" + reverseString, Toast.LENGTH_LONG).show();
} catch (ClientProtocolException e) {
Toast.makeText(this, "CPE response " + e.toString(), Toast.LENGTH_LONG).show();
// TODO Auto-generated catch block
} catch (IOException e) {
Toast.makeText(this, "IOE response " + e.toString(), Toast.LENGTH_LONG).show();
// TODO Auto-generated catch block
}
}//end postData()
这是我的 PHP 代码。
<?php
//code to reverse the string
$reversed = strrev($_POST["action"]);
echo $reversed;
?>
我也获得了在我的应用程序中使用互联网的许可。
最佳答案
从 Android 3.x 开始，您不能在主线程中执行网络操作。您需要使用 AsyncTask 或单独的线程来调用您的 postData 方法。
