清爽活动/＆QUOT;执行活动的停止未恢复＆QUOT;错误 [英] Refreshing activity / "performing stop of activity that is not resumed" error

问题描述

我想一旦GPS是通过打开的GPS设置的alertdialog启用刷新我的活动。
我实现了onResume功能，但结果我得到这个在我的logcat：

I'm trying to refresh my activity once the GPS is enabled via an alertdialog that opens the GPS settings. I implemented the onResume function but in result I get this on my logcat :

performing stop of activity that is not resumed(...)

我已经看过这个帖子，但我无法弄清楚什么是错了我的code（或我的onResume功能），以及如何从GPS设置回来后刷新我的活动。

I have looked on this post but I can't figure out what is wrong with my code (or my onResume function) and how to refresh my activity after coming back from GPS settings.

你能帮助我吗？
这里是我的 MainActivity.java

推荐答案

致电时您

gps.showSettingsAlert();//inside this use startActivityForResult(new Intent().setClass(this, MainActivity.class), result_code);

编辑：你的方法应该是在MainActivity.class不是Service作为服务没有界面，因此没有得到一点，结果那里

  public void showSettingsAlert(Context context){
            AlertDialog.Builder alertdialog = new AlertDialog.Builder(context);
            alertdialog.setTitle("Oups ! pas de données GPS");
            alertdialog.setMessage("GPS n'est pas activé sur votre appareil, voulez vous l'activer ?");

            /*
            handling the buttons :
             */
            alertdialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {


                public void onClick(DialogInterface dialog,int which) {
                    Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                    startActivityForResult(intent, RESULT_CODE_GPS);


                }
            });

            // on pressing cancel button
            alertdialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
                }
            });

            alertdialog.show();

        }

下面是你的活动结果的方法，将用户后，presses从设置页背面被调用。

---

Here is your Activity result method which will be called after user presses back from Settings page.

@SuppressLint("NewApi") @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data){
            if(requestCode == RESULT_CODE_GPS && resultCode == 0){
              //  @SuppressWarnings("deprecation")
                String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_MODE);
                if(provider != null && !provider.isEmpty()){
                    Log.v("mAINaBBB", " Location providers: "+provider);
                    //Start searching for location and update the location text when update available. 
    // Do whatever you want

                }else{
                      Log.v(, "Nothing put on");
                    //Users did not switch on the GPS
                }
            }
        }

现在在MainAcitivity自称在那里你之前

---

Now in the MainAcitivity itself call the method where you called before

if(gps.canGetlocation() ){

            double latitude = gps.getLatitude();
            double longitude = gps.getLongitude();

            device_location = new ParseGeoPoint(latitude,longitude);
            Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();

        }else{
            // can't get location
            // GPS or Network is not enabled
            // Ask user to enable GPS/network in settings

            showSettingsAlert(MainActivity.this); //**This line should be changed then**
        }
