將數據發布到android中的php服務器

Question

我想將數據發布到php服務器。 但是，當我單擊按鈕時，它不起作用。 我已經在Manifest.xml中添加了Internet權限。

我的代碼有什么問題？

public class MainActivity extends Activity {
Button sendButton;

    EditText msgTextField, msgTextField2;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        msgTextField = (EditText) findViewById(R.id.msgTextField);
        msgTextField2 = (EditText) findViewById(R.id.msgTextField2);        
        sendButton = (Button) findViewById(R.id.send);}
        public void send(View v) { //View v ?

            String msg = msgTextField.getText().toString();
            String msg2 = msgTextField2.getText().toString();

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(
                    "http://blahblah.com/myphppage");
            try {
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

                nameValuePairs.add(new BasicNameValuePair("frm_ad", msg));
                nameValuePairs.add(new BasicNameValuePair("frm_nomre", msg2));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                httpclient.execute(httppost);
                HttpResponse response = httpclient.execute(httppost);
                msgTextField.setText("");
                msgTextField2.setText("");
            } catch (ClientProtocolException e) {

            } catch (IOException e) {

            }   

    }
}

您在UIThread中沒有一個http請求。 您已使用其他Thread如何進行Asynctask。

    new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {

       HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(
            "http://blahblah.com/myphppage");
        try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

        nameValuePairs.add(new BasicNameValuePair("frm_ad", msg));
        nameValuePairs.add(new BasicNameValuePair("frm_nomre", msg2));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        httpclient.execute(httppost);
        HttpResponse response = httpclient.execute(httppost);

        } catch (ClientProtocolException e) {

        } catch (IOException e) {

        } 
            return null;
        }

        @Override
        protected void onPostExecute(Void aVoid) {
            //settext() Textview
            super.onPostExecute(aVoid);
        }

    }.execute();

試試下面的代碼：

    EditText msgTextField, msgTextField2;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        msgTextField = (EditText) findViewById(R.id.msgTextField);
        msgTextField2 = (EditText) findViewById(R.id.msgTextField2);        
        sendButton = (Button) findViewById(R.id.send);
        sendButton.setOnClickListener(send)
}

       private OnClickListener send = new OnClickListener() {
        @Override
          public void onClick(final View v) {


            String msg = msgTextField.getText().toString();
            String msg2 = msgTextField2.getText().toString();

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(
                    "http://blahblah.com/myphppage");
            try {
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

                nameValuePairs.add(new BasicNameValuePair("frm_ad", msg));
                nameValuePairs.add(new BasicNameValuePair("frm_nomre", msg2));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                httpclient.execute(httppost);
                HttpResponse response = httpclient.execute(httppost);
                msgTextField.setText("");
                msgTextField2.setText("");
            } catch (ClientProtocolException e) {

            } catch (IOException e) {

            } 



    }
    }
