如何在Android应用程序上更改抽屉切换图标？

我在android应用程序上创建了一个抽屉开关。它显示在屏幕的左上角。单击切换时，左侧将显示列表视图项。 以下屏幕为主屏幕：

当我单击切换时，它将显示如下：

现在，我想通过以下代码更改切换按钮的图标：

mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer);
mDrawerToggle.setDrawerIndicatorEnabled(false);

切换图标已更改为“我的可绘制”，但单击切换时不会显示listview项目。我想知道为什么更改切换图标会禁用切换单击

下面是我的活动课：

public class MainActivity extends AppCompatActivity {
    private DrawerLayout mDrawerLayout;
    private ListView mDrawerList;
    private ActionBarDrawerToggle mDrawerToggle;
    private String[] mPlanetTitles;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

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

        mDrawerList = (ListView) findViewById(R.id.left_drawer);
        mPlanetTitles = getResources().getStringArray(R.array.planets_array);
        // Set the adapter for the list view
        mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, mPlanetTitles));
        mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

        mDrawerToggle = new ActionBarDrawerToggle(
                this,                  /* host Activity */
                mDrawerLayout,
                R.string.drawer_open,  /* "open drawer" description for accessibility */
                R.string.drawer_close  /* "close drawer" description for accessibility */
        ) {
            public void onDrawerClosed(View view) {
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            public void onDrawerOpened(View drawerView) {
                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        };
        mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer);
//        mDrawerToggle.setDrawerIndicatorEnabled(false);
        mDrawerLayout.addDrawerListener(mDrawerToggle);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if(mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Pass any configuration change to the drawer toggls
        mDrawerToggle.onConfigurationChanged(newConfig);
    }


    /* The click listner for ListView in the navigation drawer */
    private class DrawerItemClickListener implements ListView.OnItemClickListener {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        }
    }
}

更改切换按钮的图标后使用syncState

mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer);
mDrawerToggle.setDrawerIndicatorEnabled(false);
mDrawerToggle.syncState();

v7 ActionBarDrawerToggle实际上只做两件事：打开/关闭抽屉，并提供汉堡图标及其动画。调用SetDrainerIndicatorEnabledFalse将删除其图标，但也会禁用切换。如果你不想要那个图标，那么你最好不要使用ActionBarDrawerToggle，自己处理打开/关闭抽屉的操作

首先，删除ActionBarDrawerToggle的所有代码。 然后使用getSupportActionBar.setHomeAsUpIndicator设置所需图标。 在OnOptions ItemSelected中，如果菜单项的ID为android.R.ID.home，请根据需要打开或关闭抽屉。 最后，ActionBarDrawerToggle的DrawerLayout.DrawerListener功能可以替换为基本的SimpleDrawerListener。

添加此代码后，可以更改图标，但单击该图标不会使listview项目显示在左侧。我看到Mike在回答我的问题时说ActionBarDrawerToggle不支持更改图标。也许我需要一个不同的方法that@ZhaoYiActionBarDrawerToggle确实允许您在一定程度上更改图标。但是，您设置的图标必须是DrawerArrowDrawable子类，这可能不是您想要的。如果你仍然需要解决这个问题，我可以发布一个我在上面的评论中建议的例子。@MikeM。演示代码非常有用。请张贴一个例子，如果这对你来说不难。谢谢
