public class MyFragment extends ListFragment {

@Override

     ListView lv =(ListView) v.findViewById(android.R.id.list);


        // Listview on item click listener

            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long id) {
                // getting values from selected ListItem
                String titulo = ((TextView) v.findViewById(R.id.title))
                        .getText().toString();
                String contenido = ((TextView) v.findViewById(R.id.content))
                .getText().toString();
                String fecha = ((TextView) v.findViewById(R.id.date))
                        .getText().toString();

                // Starting new detail

有人知道如何用代码打开Android的设置屏幕？谢谢.

我希望我的应用程序能够检测我的设备是否有互联网连接.我写了这段代码,但它不起作用.这是代码:

import android.content.Intent;
import android.net.ConnectivityManager;

import android.widget.Toast;

public class navegando extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        comprobar();
    }

    private void comprobar() {
        Context context = null;
        // TODO Auto-generated method stub
        if(navegando.isOnline(context)== false) {
            new AlertDialog.Builder(this).setTitle("Advertencia").setMessage("No hay internet").setNeutralButton("Close", null).show();
           finish();
        }

我在php中做一个Web服务来将数据编码为json.我的PHP代码是:

    function getProgramDay($day)
{

    global  $DDBB_SERVER, $DDBB_USER, $DDBB_PASSWORD, $DDBB;



    $sql = "SELECT program.id, programa.name FROM `mybd` WHERE program.day = '" . $day . "'";


    $con = mysqli_connect($DDBB_SERVER, $DDBB_USER, $DDBB_PASSWORD, $DDBB);

    if (!$con) {
        die('Error de Conexión (' . mysqli_connect_errno() . '): ' . mysqli_connect_error());
    }

    if (!mysqli_set_charset($con, "utf8")) {
        die("Error loading character set utf8:" . mysqli_error($con));
    }

    $result = mysqli_query($con, $sql);

    $res = array();

    // Prepare data
    while ($row = mysqli_fetch_assoc($result)) {
        $res[] = $row;
    }

    // Free resultset
    mysqli_free_result($result); …
