如何使用 Appcompat v7 21、Toolbar 和 DrawerLayout 将 Burger 动画化为箭头

Question

我正在使用带有 android.support.v4.widget.DrawerLayout 的 android.support.v7.widget.Toolbar。它工作正常，导航抽屉关闭时显示汉堡图标，抽屉打开时显示箭头图标。 我想在应用程序中的某些事件上禁用抽屉并将汉堡图标设置为箭头。我尝试将锁定模式设置为关闭，但 v7.app.ActionBarDrawerToggle 仍然显示 Burger 并打开 Drawer。

mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

有什么想法吗？ 谢谢！

更新：

不，我可以更改图标的状态，并且可以启用/禁用抽屉，但动画不适用于这种方法：

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    Toolbar toolbar = (Toolbar) findViewById(R.id.application_toolbar);
    setSupportActionBar(toolbar);

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.string1, R.string.string2) {
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
        }

        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
        }
    };

    //mDrawerLayout.setDrawerListener(mDrawerToggle); // not needed
    ...
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) {
        case android.R.id.home:
            if (mDrawerLayout.getDrawerLockMode(GravityCompat.START) == LOCK_MODE_UNLOCKED) {
                showDrawer();
            } else {
                handleBackButtonPress(); // On this stage the home button is a <-
            }
    }
    ...
}

private void setDrawerState(boolean isEnabled) {
    if (isEnabled) {
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
        mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_UNLOCKED);
        mDrawerToggle.syncState();

    } else {
        mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
        mDrawerToggle.onDrawerStateChanged(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
        mDrawerToggle.syncState();
    }
}

抽屉位于工具栏的顶部。

主要部分如下：

<style name="AppTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

我创建了一个具有类似功能的小应用程序

主活动

public class MyActivity extends ActionBarActivity {

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

        DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
        android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
        ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(
                this,
                drawerLayout,
                toolbar,
                R.string.open,
                R.string.close
        )

        {
            public void onDrawerClosed(View view)
            {
                super.onDrawerClosed(view);
                invalidateOptionsMenu();
                syncState();
            }

            public void onDrawerOpened(View drawerView)
            {
                super.onDrawerOpened(drawerView);
                invalidateOptionsMenu();
                syncState();
            }
        };
        drawerLayout.setDrawerListener(actionBarDrawerToggle);

        //Set the custom toolbar
        if (toolbar != null){
            setSupportActionBar(toolbar);
        }

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        actionBarDrawerToggle.syncState();
    }
}

我的那个 Activity 的 XML

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MyActivity"
    android:id="@+id/drawer"
    >

    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        <include layout="@layout/toolbar_custom"/>
    </FrameLayout>
    <!-- The navigation drawer -->
    <ListView
        android:layout_marginTop="?attr/actionBarSize"
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#457C50"/>


</android.support.v4.widget.DrawerLayout>

我的自定义工具栏 XML

<?xml version="1.0" encoding="utf-8"?>

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

    android:id="@+id/toolbar"
    android:background="?attr/colorPrimaryDark">
    <TextView android:text="U titel"
        android:textAppearance="@android:style/TextAppearance.Theme"
        android:textColor="@android:color/white"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
</android.support.v7.widget.Toolbar>
