Question

         /**
         * Send Button click event.
         **/
        send.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                      NetAsync(view);

            }
        });
    }

点击事件＆＃34; NetAsync（查看）＆＃34;执行并将gps坐标发送到服务器，但我想要的是，而不是在用户启动应用程序时使用按钮点击事件＆＃34; NetAsync（view）＆＃34;每10分钟后自动执行一次。请告诉我如何做到这一点，因为我是Android编程的新手。

Answer 1

你可以像这样使用TimerTask和Timer类来实现它

final Handler handler = new Handler();
        Timer timer = new Timer();
        TimerTask doAsynchronousTask = new TimerTask() {       
            @Override
            public void run() {
                handler.post(new Runnable() {
                    public void run() {       
                        try {
                                                 //your method here
                        } catch (Exception e) {
                        }
                    }
                });
            }
        };
        timer.schedule(doAsynchronousTask, 0, 600000); //execute in every 10 minutes

尝试以下内容：

TimerTask scanTask;
final Handler handler = new Handler();
Timer t = new Timer();

public void doWifiScan(){

scanTask = new TimerTask() {
        public void run() {
                handler.post(new Runnable() {
                        public void run() {
                        NetAsync(view);
                        }
               });
        }};


    t.schedule(scanTask, 300, 600000); 

 }

使用处理程序您可以轻松实现目标，请遵循以下代码，

    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {

        @Override
        public void run() {
            if (!isSyncStart) {
                startSyncProcess(true); //write Your Method Here!
            }
        }
    }, 600000);

将AlarmManager与广播接收器一起使用

private PendingIntent mPingAlarmPendIntent;
private static final String PING_ALARM = "com.sithagi.PING_ALARM";
private Intent mPingAlarmIntent = new Intent(PING_ALARM);
private BroadcastReceiver mPingAlarmReceiver = new PingAlarmReceiver();


mPingAlarmPendIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, mPingAlarmIntent,
                    PendingIntent.FLAG_UPDATE_CURRENT);
    // Each and every 15 minutes will trigger onReceive of your BroadcastReceiver   
((AlarmManager)getSystemService(Context.ALARM_SERVICE)).setInexactRepeating(AlarmManager.RTC_WAKEUP, 
        System.currentTimeMillis() + (AlarmManager.INTERVAL_FIFTEEN_MINUTES), AlarmManager.INTERVAL_FIFTEEN_MINUTES, mPingAlarmPendIntent);


// Register the receiver 
registerReceiver(mPingAlarmReceiver, new IntentFilter(PING_ALARM));

// To cancel Alarm Service
((AlarmManager)getSystemService(Context.ALARM_SERVICE)).cancel(mPingAlarmPendIntent);

// unregister the receiver onDestroy or if you want stop
unregisterReceiver(mPingAlarmReceiver);


 /**
 * BroadcastReceiver will trigger 
 */
private class PingAlarmReceiver extends BroadcastReceiver {
    public void onReceive(Context ctx, Intent i) {
        // Do your work here 
    }
}
