将用户发送到具有意图的设置后如何返回我的应用程序

Question

我试图找到一种方法，在用户自动启用位置服务后如何将用户返回到我的应用，而无需用户按下后退按钮。 我检查是否启用了位置服务：

if( !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
            alertForNoLocationEnabled();
        }else {

            locationManager.requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, 0, 0, new MyLocationListener());
        }
private void alertForNoLocationEnabled() {
    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
    builder.setTitle(R.string.network_not_found_title);  // network not found
    builder.setMessage(R.string.network_not_found_message); // Want to enable?
    builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialogInterface, int i) {
            toggleSwipeRefreshLayoutsOff();
            Intent intent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
            startActivity(intent);
        }
    });
    builder.setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            toggleSwipeRefreshLayoutsOff();
        }
    });
    AlertDialog dialog = builder.create();
    dialog.setCanceledOnTouchOutside(false);
    dialog.show();
}

并且在用户打开我想要的位置服务后，我自动将用户带回我的应用程序而不是按后退按钮。 请任何想要分享它的人。

这可能有用。

 builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialogInterface, int i) {
        toggleSwipeRefreshLayoutsOff();

    AsyncTask.execute(new Runnable() {
        @Override
       public void run() {
         long fortySecondsFromNow = System.currentTimeMillis() + 40*1000
         while((System.curremtTimeMillis < fortySecondsFromNow)
              && !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))) {
             Thread.sleep(300);
          } 
        if(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER){
          Intent intent = new Intent(context, YourActivity.class);
          intent.setAction(Intent.ACTION_MAIN);
          intent.addCategory(Intent.CATEGORY_LAUNCHER);
          startActivity(intent);
          //Do what u want
           } 

        });

        Intent intent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
        startActivity(intent);
    }
