Question

我们有一个作为父应用程序“A”的应用程序，我们使用来自父应用程序“A”的url方案（安装在同一设备中）调用子应用程序“B”，然后将应用程序推送到后台。点击父应用“A”的图标，它将启动到子应用“B”的同一页面。这种行为我们只在Android 7中看到，在Android下面它只打开了父App“A”。所以只是想知道如果它是android 7的预期行为？

Answer 1

最后我才知道它不是设备特定的，但它取决于我们如何打开子应用程序。

如果想要将子应用程序与父应用程序分离，只需在调用子应用程序时放在代码下面。

  private void navigationDrawer() {

        mTitle = mDrawerTitle = getTitle();
        // mNavigationDrawerItemTitles = getResources().getStringArray(R.array.navigation_drawer_items_array);

        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);

        LayoutInflater inflater = getLayoutInflater();
        View listHeaderView = inflater.inflate(R.layout.list_view_header, null, false);
        mDrawerList.addHeaderView(listHeaderView, null, false);

        setupToolbar();

        DataModel[] drawerItem = new DataModel[6];

        drawerItem[0] = new DataModel(R.drawable.dashboard_icon, "Dashboard");
        drawerItem[1] = new DataModel(R.drawable.cal_icon, "Calender");
        drawerItem[2] = new DataModel(R.drawable.classes, "Classes");
        drawerItem[3] = new DataModel(R.drawable.message_icon_hdpi, "Message Center");
        drawerItem[4] = new DataModel(R.drawable.profile, "Profile & Setting");
        drawerItem[5] = new DataModel(R.drawable.bulletin_icon, "Bulletin Board");

        getSupportActionBar().setDisplayHomeAsUpEnabled(false);
        getSupportActionBar().setHomeButtonEnabled(true);

        DrawerItemCustomAdapter adapter = new DrawerItemCustomAdapter(this, R.layout.list_view_item_row, drawerItem);
        mDrawerList.setAdapter(adapter);
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerLayout.setDrawerListener(mDrawerToggle);
        setupDrawerToggle();


    }

    private class DrawerItemClickListener implements ListView.OnItemClickListener {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            selectItem(position - 1);
        }


    }

    private void selectItem(int i) {
        Fragment fragment = null;

        switch (i) {
            case 0:
                fragment = new Fragment_DashBoard();
                // toolbar.setTitle("Dashboard");
                Titletv.setText("Dashboard");
                break;
            case 1:
                fragment = new Fragment_Calender();
                // toolbar.setTitle("Calender");
                Titletv.setText("Calender");

                break;
            case 2:
                fragment = new Fragment_Classes();
                // toolbar.setTitle("Classes");
                Titletv.setText("Classes");
                break;
            case 3:
                fragment = new Fragment_MessageCenter();
                // toolbar.setTitle("Message");
                Titletv.setText("Messages");
                break;
            case 4:
                fragment = new Fragment_ProfileSetting();
                // toolbar.setTitle("Profile");
                Titletv.setText("Profile");

                break;

            case 5:
                fragment = new Fragment_BulletinBoard();
                //toolbar.setTitle("Bulletin Board");
                Titletv.setText("Bulletin Board");

                break;

            default:
                break;
        }


        if (fragment != null) {

            FragmentManager fragmentManager = getSupportFragmentManager();
            FragmentTransaction trans = fragmentManager.beginTransaction();
            fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).addToBackStack(null).commit();

            mDrawerList.setItemChecked(i, true);
            mDrawerList.getItemAtPosition(i);
            // setTitle(mNavigationDrawerItemTitles[position]);
            mDrawerLayout.closeDrawer(mDrawerList);


        } else {
            Log.e("MainActivity", "Error in creating fragment");
        }


    }
