我正在使用一个应用程序,当我选择(自动发送按钮打开)时,它必须每 5 秒向服务器发送一次 GPS 位置。我是 android 新手,所以我不知道如何制作开/关按钮,以及如何调用在按钮打开时每 5 秒发送一次数据的方法。
它必须每 5 秒调用一次的方法:
public void postData() throws ClientProtocolException, IOException, Exception {
String longitude="UK";
String latitude="UK";
String altitiude="UK";
String time="";
String speed="";
getCurrentLocation(); // gets the current location and update mobileLocation variables
if (mobileLocation != null) {
locManager.removeUpdates(locListener); // This needs to stop getting the location data and save the battery power.
longitude = ""+mobileLocation.getLongitude();
latitude = "" + mobileLocation.getLatitude();
altitiude = "" + mobileLocation.getAltitude();
String accuracy = "Accuracy" + mobileLocation.getAccuracy();
time = "" + mobileLocation.getTime();
speed =""+ (int)(4*mobileLocation.getSpeed());
editTextShowLocation.setText(longitude + "\n" + latitude + "\n"
+ altitiude + "\n" + accuracy + "\n" + time+ "\n" + speed);
} else {
editTextShowLocation.setText("Sorry, location is not determined");
}
String url = "http://www.itrack.somee.com/post.aspx?id="+"f1"+"&long="+longitude+"&lat="+latitude+"&alt="+altitiude+"&speed="+speed;
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
try {
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
}
}
