当我调用startResolutionForResult时,android-onActivityResult()不会在片段中执行

问题,当我打电话使用GoogleApiClient以编程方式启用gps片段…
我的代码是……

 final Status status = result.getStatus();
                final LocationSettingsStates state = result.getLocationSettingsStates();
                switch (status.getStatusCode())
                {
                    case LocationSettingsStatusCodes.SUCCESS:
                        // All location settings are satisfied. The client can initialize location
                        // requests here.
                        getCurrentLocation();
                        break;
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the user
                        // a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            status.startResolutionForResult(getActivity(), REQUEST_ID_GPS_PERMISSIONS);
                        } catch (IntentSender.SendIntentException e) {
                            // Ignore the error.
                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        break;
                }

我的onActivityResult是

 final Status status = result.getStatus();
                final LocationSettingsStates state = result.getLocationSettingsStates();
                switch (status.getStatusCode())
                {
                    case LocationSettingsStatusCodes.SUCCESS:
                        // All location settings are satisfied. The client can initialize location
                        // requests here.
                        getCurrentLocation();
                        break;
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the user
                        // a dialog.
                        try {
                            // Show the dialog by calling startResolutionForResult(),
                            // and check the result in onActivityResult().
                            status.startResolutionForResult(getActivity(), REQUEST_ID_GPS_PERMISSIONS);
                        } catch (IntentSender.SendIntentException e) {
                            // Ignore the error.
                        }
                        break;
                    case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                        // Location settings are not satisfied. However, we have no way to fix the
                        // settings so we won't show the dialog.
                        break;
                }

但我的onActicvityResult()没有在片段中执行.
问题出在哪儿？？？
帮帮我…..提前谢谢.

解决方法:

由于片段被放置在活动内部并且它们的生命周期与包含活动的生命周期紧密耦合.

1)在活动中：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Fragment frg = getSupportFragmentManager().findFragmentById(R.id.fragment_container_main);
    if (frg != null) {
        frg.onActivityResult(requestCode, resultCode, data);
    }
}

现在片段的容器活动将为片段提供意图数据,请求代码和结果,以便获取数据和结果片段,你必须覆盖片段中的onActivityResult(int requestCode,int resultCode,Intent data)

2)在片段中

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

}

在那里你将从你的父活动获得回调.做你想要发送的任何内容或获得回调.
