android - 如何为没有工具栏的 ActionBarDrawerToggle v7 设置抽屉切换图标 (`hamburger`)

Question

我正在使用 android.support.v7.app.ActionBarActivity 中的操作栏，所以我的 Activity 声明如下:

public class MyActivity extends ActionBarActivity {

我正在阅读说明如何添加抽屉的教程:

DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close);

这是为了 import android.support.v4.app.ActionBarDrawerToggle。现在我决定使用 v7，因为 v4 已被弃用，但 v7 的构造函数不接受抽屉图标。我用谷歌搜索，发现解决方案是使用接受 toolbar 的构造函数风格:

ActionBarDrawerToggle(this, drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

但我不使用工具栏。所以我不明白如何在没有工具栏的情况下使用 v7 设置图标。我应该改用工具栏吗？

嘿，你在这里找到了解决方案..

private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.toolbar);

if (toolbar != null) {
    setSupportActionBar(toolbar);
    toolbar.setNavigationIcon(R.drawable.ic_drawer);

    mDrawerToggle = new ActionBarDrawerToggle(this,
                mDrawerLayout,
                toolbar,
                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);
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
        }
    };

    // Set the drawer toggle as the DrawerListener
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    mDrawerToggle.syncState();

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
}

这也是一个很好的方法，我个人使用这个。

public class MyActionBarDrawerToggle extends android.support.v7.app.ActionBarDrawerToggle {

    public MyActionBarDrawerToggle(Activity activity, final DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes) {
        super(activity, drawerLayout, toolbar, openDrawerContentDescRes, closeDrawerContentDescRes);

        setHomeAsUpIndicator(R.drawable.drawer_toggle);
        setDrawerIndicatorEnabled(false);

        setToolbarNavigationClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                drawerLayout.openDrawer(Gravity.LEFT);
            }
        });
     }
}

谢谢。
