单击菜单图标时未打开导航抽屉

Question

导航抽屉没有打开点击导航图标（即左上角的3条水平线）。在Lollipop它工作，但问题是Kitkat和果冻豆它不工作？

Answer 1

我今天面对这个问题。

我认为您的 DrawerLayout 可能位于根视图，并且您设置宽度和高度= "match_parent"。

在 Lolipop 中，工具栏会弹出，因此可以点击。但是在 KitKat 或更低版本中，它会点击DrawerLayout，而不是工具栏（工具栏位于DrawerLayout后面）。

我的解决方案是在DrawerLayout中设置MarginTop = "?attr/actionBarSize"。

希望它会帮助你认为它已经很久了:)）

你的代码看起来很乱，看看我的，它运作得很好。

public class HomeActivity extends ActionBarActivity implements
        DrawerCloseListener {
    private Toolbar toolbar;
    private DrawerLayout drawer;
    private ActionBarDrawerToggle drawerToggle;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        toolbar = (Toolbar) findViewById(R.id.home_toolbar);
        setSupportActionBar(toolbar);
        drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar,
                R.string.app_name, R.string.app_name);
        drawerToggle.setHomeAsUpIndicator(R.drawable.icon_nav);
        drawer.setDrawerListener(drawerToggle);
    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        toolbar.setTitle("");
        toolbar.setNavigationIcon(R.drawable.icon_nav);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (drawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        // TODO Auto-generated method stub
        super.onConfigurationChanged(newConfig);
        drawerToggle.onConfigurationChanged(newConfig);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onPostCreate(savedInstanceState);
        drawerToggle.syncState();
    }

    @Override
    public void onBackPressed() {
        // TODO Auto-generated method stub
        if (drawer.isDrawerOpen(Gravity.LEFT | Gravity.START)) {
            drawer.closeDrawers();
            return;
        }
        super.onBackPressed();
    }

    @Override
    public void onDrawerClose() {
        // TODO Auto-generated method stub
        if (drawer.isDrawerOpen(Gravity.LEFT | Gravity.START)) {
            drawer.closeDrawers();
        }
    }
}
