启动谷歌地图意图后返回活动

Question

我有MainActivity上有一个片段，当用户点击片段时，用户会导航到另一个片段，在最后一个片段上有一个按钮来启动谷歌地图导航，这是代码：

@Override
public void onClick(View v) {
    String url = "https://www.google.com/maps/dir/?api=1&destination=-17.174498,12.634206";
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
    startActivity(intent);
    getActivity().overridePendingTransition(R.anim.slide_up_in, R.anim.slide_up_out);
}

问题是，在地图启动后，我希望用户在按下back时返回到我的应用程序，而不是Launcher。

有没有办法做到这一点。

这是我的完整代码：

主体活动

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        setTheme(R.style.AppTheme);
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, new SplashFragment())
                    .commit();
        }
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.fragment_splash, container, false);
    view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Transition transition = new Fade(Visibility.MODE_IN);
            transition.setDuration(400);

            Fragment fragment = MapsFragment.newInstance();

            // set transition animation
            fragment.setEnterTransition(transition);
            fragment.setAllowEnterTransitionOverlap(true);
            fragment.setAllowReturnTransitionOverlap(true);

            // add second fragment by replacing first
            getFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, fragment)
                    .addToBackStack(null)
                    .commit();
        }
    });

    return view;
}

Answer 1

您必须向意图添加标志，如下所示

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
startActivity(intent);
getActivity().overridePendingTransition(R.anim.slide_up_in, R.anim.slide_up_out);

请试着告诉我。
