吐司不会从屏幕上消失

问题描述

我有我的简单的android aplication一个问题，即使用GPS线。

I have a problem with my simple android aplication that use GPS cords.

我班MyLocationListener实现LocationListener的，并且有一个静态方法调用：

My class MyLocationListener implements LocationListener, and there is a static method call:

    String strText ="My current location is: " + "Latitude = " +  location.getLatitude() + " Longitude= " + location.getLongitude();
    Toast.makeText(GpsModule.cont, strText, Toast.LENGTH_SHORT).show();

问题是显示此字符串。它说明，并且永远不会结束。当我preSS后退键主菜单，甚至当我关闭应用程序它不断地显示出来。任何线索？我怎样才能解决这个问题呢？

Problem is with displaying this string. It's showing up, and never ends. When I press back button for main menu and even when I close application it's showing up constantly. Any clue? How can I resolve this problem?

GpsModule类：

GpsModule Class:

public class GpsModule extends Activity {

public static Context cont;
//public static WebView position;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.gps);
    cont = getApplicationContext();
    //position = new WebView(cont);

    //position = (WebView) findViewById(R.layout.gps);
    //position.getSettings().setJavaScriptEnabled(true);


    LocationManager locManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    LocationListener locListener = new MyLocationListener();
    locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
}

MyLocationListener类：

MyLocationListener class:

@SuppressLint("ShowToast")

公共类MyLocationListener实现LocationListener的{

public class MyLocationListener implements LocationListener{

public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub
    location.getLatitude();
    location.getLongitude();

    String strText ="My current location is: " + "Latitude = " +  location.getLatitude() + " Longitude= " + location.getLongitude();
    Toast.makeText(GpsModule.cont, strText, Toast.LENGTH_SHORT).show();

}

public void onProviderDisabled(String provider) {
    // TODO Auto-generated method stub
    Toast.makeText(GpsModule.cont, "GPS disabled", Toast.LENGTH_SHORT).show();
}

public void onProviderEnabled(String provider) {
    // TODO Auto-generated method stub
    Toast.makeText(GpsModule.cont, "GPS enabled", Toast.LENGTH_SHORT).show();
}

public void onStatusChanged(String provider, int status, Bundle extras) {
    // TODO Auto-generated method stub

}

}

推荐答案

请阅读方法的文档 LocationManager.requestLocationUpdates（）。

特别的参数：

    minTime     minimum time interval between location updates, in milliseconds.

每10秒尝试值10000。在生产中，你应该考虑比分钟更多的价值。

Try value 10'000 for every 10 sec. In production you should consider value more than mins.
