Question

这是点击事件。

view.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {


        v.setBackgroundResource(R.color.colorTim);

        FragmentManager fragmentManager = ((AppCompatActivity)context).getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

        HienThiSanPhamTheoDanhMucActivity hienThiSanPhamTheoDanhMucActivity = new HienThiSanPhamTheoDanhMucActivity();

        Bundle bundle = new Bundle();

        bundle.putInt("MALOAI",loaiSanPhams.get(groupPosition).getMALOAISP());
        bundle.putBoolean("KIEMTRA",false);
        bundle.putString("TENLOAI",loaiSanPhams.get(groupPosition).getTENLOAISP());

        hienThiSanPhamTheoDanhMucActivity.setArguments(bundle);
        fragmentTransaction.addToBackStack("TrangChuActivity");
        fragmentTransaction.replace(R.id.themFragment,hienThiSanPhamTheoDanhMucActivity);
        fragmentTransaction.commit();
        return false;
    }
});

结果将显示在片段中，但仍会显示抽屉菜单。我该怎么做才能关闭它？任何人都给我建议如何解决这个，任何帮助非常感谢。谢谢。

Answer 1

每次触摸任何项目时，在onTouchListener内添加此内容都会关闭抽屉：

drawer.closeDrawer(GravityCompat.START);

Answer 2

view.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {


            v.setBackgroundResource(R.color.colorTim);

            FragmentManager fragmentManager = ((AppCompatActivity)context).getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

            HienThiSanPhamTheoDanhMucActivity hienThiSanPhamTheoDanhMucActivity = new HienThiSanPhamTheoDanhMucActivity();

            Bundle bundle = new Bundle();

            bundle.putInt("MALOAI",loaiSanPhams.get(groupPosition).getMALOAISP());
            bundle.putBoolean("KIEMTRA",false);
            bundle.putString("TENLOAI",loaiSanPhams.get(groupPosition).getTENLOAISP());

            hienThiSanPhamTheoDanhMucActivity.setArguments(bundle);
            fragmentTransaction.addToBackStack("TrangChuActivity");
            fragmentTransaction.replace(R.id.themFragment,hienThiSanPhamTheoDanhMucActivity);
            fragmentTransaction.commit();

            DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
            drawer.closeDrawer(GravityCompat.START);
            return false;
        }
    });

Answer 3

将以下代码添加到MainActivity.java的onCreate（）中：

 NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(mOnNavigationDrawerItemSelectedListener);

然后添加以下代码：

    private NavigationView.OnNavigationItemSelectedListener mOnNavigationDrawerItemSelectedListener
        = new NavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
        Fragment fragment;
        int id = menuItem.getItemId();

        switch (id) {
            case R.id.nav_reload_downloaded_tasks:
                toolbarTitle.setText(R.string.menu_reload_downloaded_tasks);
                fragment = new ReloadDownloadedTasksFragment();
                loadFragment(fragment);
                break;

            case R.id.nav_download_base_data:
                toolbarTitle.setText(R.string.menu_download_base_data);
                fragment = new ReloadDownloadedTasksFragment();
                loadFragment(fragment);
                break;
        }

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }
};

这：

  private void loadFragment(Fragment fragment) {
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
    transaction.replace(R.id.nav_host_fragment, fragment);
    transaction.addToBackStack(null);
    transaction.commit();
}
