Question

如图所示，我在同一个活动中使用DrawerLayout和TabLayout。因此，屏幕基本上是TabLayout的ViewPager（片段标签）。当我打开导航抽屉时，它会重叠，如图所示。

我已经在Android NavigationDrawer transparency尝试了解决方案（与此问题有同样的问题）

但它没有用。

我也尝试将android:alpha="255"添加到ListView，但没有用。

以下是我的代码：

MainActivity.java

public class UserMainActivity extends AppCompatActivity {

    private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mToggle;

    private SectionsPageAdapter pageAdapter;

    ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_user_main);

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.container, new MatchListTab());

        mDrawerLayout = (DrawerLayout) findViewById(R.id.nav_layout);

        mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);

        mDrawerLayout.addDrawerListener(mToggle);
        mToggle.syncState();

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        pageAdapter = new SectionsPageAdapter(getSupportFragmentManager());

        viewPager = (ViewPager) findViewById(R.id.container);
        setupViewPager(viewPager);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager((viewPager));


    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        if(mToggle.onOptionsItemSelected(item)) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    // Adds fragments to SectionsPageAdapter and gives names for the corresponding tab

    private void setupViewPager(ViewPager viewPager) {
        SectionsPageAdapter adapter = new SectionsPageAdapter(getSupportFragmentManager());
        adapter.addFragment(new MatchListTab(), "Scores");
        adapter.addFragment(new MatchListTab(), "Live");
        adapter.addFragment(new MatchListTab(), "Favorite");
        adapter.addFragment(new MatchListTab(), "Data");
        viewPager.setAdapter(adapter);
    }
}

activity_main.xml中

list.xml

    <ListView

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:alpha="255"/>

</LinearLayout>

我该如何解决这个问题？

Android导航抽屉是透明的，与ListView重叠
