我在我的活动有一个问题，它可以控制到Android手机GPS设置有用户打开/关闭GPS，但我无法retrun回到我的活动。当我preSS后退按钮，它直接将家里的移动，而不是从那里我将信号发送到设置回来我的活动。谁能告诉我这种情况的解决方案。

 如果（！lm.isProviderEnabled（LocationManager.GPS_PROVIDER））{
    startActivityForResult（新意图（Settings.ACTION_LOCATION_SOURCE_SETTINGS），1）;
 

  @覆盖
保护无效onActivityResult（INT申请code，INT结果code，意图数据）{
    Log.e（，OnActivity结果......）;
    super.onActivityResult（要求code，因此code，数据）;

    如果（结果code == GPS_LOC）{
       开关（要求code）{
          案例GPS_LOC：
              //super.onCreate(inst）;
              super.onResume（）;
              //super.finish（）;
           打破;
        }
     }
 }
 

解决方案

我的作品。你确定你有ACCESS_FINE_LOCATION权限集中在你的清单？你肯定startActivityForResult（）被调用？

此外，什么是GPS_LOC？

下面是我的code的作品：

 公共类主要的扩展活动{
    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;

        findViewById（R.id.button1）.setOnClickListener（新OnClickListener（）{
            @覆盖
            公共无效的onClick（视图v）{
                startActivityForResult（新意图（Settings.ACTION_LOCATION_SOURCE_SETTINGS），1）;
            }
        }）;
    }

    @覆盖
    保护无效onActivityResult（INT申请code，INT结果code，意图数据）{
        super.onActivityResult（要求code，因此code，数据）;
        如果（结果code == 1）{
           开关（要求code）{
              情况1：
               打破;
            }
         }
     }
}
 

I am having a problem in my Activity, which can take the control to the android mobile GPS settings to have user to switch on/off the GPS, But I am unable to retrun back to my activity. when I press back button, It is directly going to Home of the mobile, not coming back my Activity from where I send signal to settings. can anyone tell me the solution for this.

if(!lm.isProviderEnabled(LocationManager.GPS_PROVIDER )) { 
    startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), 1);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.e("","OnActivity Result...");
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == GPS_LOC) {
       switch (requestCode) {
          case GPS_LOC:
              //super.onCreate(inst);
              super.onResume();
              //super.finish();
           break;
        }
     }  
 }

Works for me. Are you sure you have ACCESS_FINE_LOCATION permission set in your manifest? Are you sure startActivityForResult() is being called?

Also, what is GPS_LOC?

Here's my code that works:

public class main extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        findViewById(R.id.button1).setOnClickListener( new OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivityForResult(new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS), 1);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == 1) {
           switch (requestCode) {
              case 1:
               break;
            }
         }  
     }
}
