Question

我正在关注建议使用V4 Navigation Drawer的Android教程，它应该在左侧为我提供一个汉堡包导航图标。相反，如果我使用一个图标，我会得到这个结果：

如果我使用另一个 类似的 图标，那就更糟了，占据了所有空间：

我不明白：

1）如何以左侧方式使用第二个图标，而其他图标继续出现，就像人们对导航抽屉的期望一样？

2）为什么两个不同的图标有这么不同的行为，毕竟我用gimp处理它们给它们200x200像素尺寸

我的主要班级：

 import android.support.v4.app.ActionBarDrawerToggle;
 import android.support.v4.widget.DrawerLayout;

 public class MainActivity extends Activity{

 @Override
protected void onCreate(Bundle savedInstanceState) {

getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
getActionBar().setBackgroundDrawable(new   ColorDrawable(Color.parseColor("#00000000")));
getActionBar().setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#550000ff")));

    super.onCreate(savedInstanceState);


        setContentView(R.layout.activity_main);    
String[] provaListaDrawer = {"List1", "List2", "List3"};
        mTitle = mDrawerTitle = getTitle();

        DrawerLayout mDrawerLayout =
                (DrawerLayout) findViewById(R.id.drawer_layout);
        actionBarDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.app_drawer, R.string.drawer_open, R.string.drawer_close)

        {

            /**
             * Called when a drawer has settled in a completely closed state.
             */
            public void onDrawerClosed(View view) {
                super.onDrawerClosed(view);
                getActionBar().setTitle(mTitle);
                Log.d("IVO", "onDrawerClosed");
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            /**

             */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);
                getActionBar().setTitle(mDrawerTitle);
                Log.d("IVO", "onDrawerOpened");

                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        }
        ;

        ListView mDrawerList = (ListView) findViewById(R.id.left_drawer);

     mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_view,provaListaDrawer));

        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

mDrawerLayout.setDrawerListener(actionBarDrawerToggle);
     getActionBar().setDisplayHomeAsUpEnabled(true);

//     Toolbar parent =(Toolbar) customView.getParent();
//        parent.setContentInsetsAbsolute(0,0);




    }
    //other methods
    }
