在AppCompatActivity中自定义toolbar出现的问题

使用AppCompatActivity自定义toolbar的问题，布局如下：

<FrameLayout        xmlns:android="http://schemas.android.com/apk/res/android"        android:layout_width="match_parent"        android:layout_height="match_parent">    <RelativeLayout            android:layout_width="match_parent"            android:layout_height="match_parent">        <FrameLayout                android:id="@+id/base_layout_container"                android:layout_width="match_parent"                android:layout_height="match_parent"                android:layout_below="@+id/base_toolbar"                android:background="@android:color/white">        </FrameLayout>        <android.support.v7.widget.Toolbar                android:id="@id/base_toolbar"                android:layout_width="match_parent"                android:layout_height="@dimen/toolbar_height">        </android.support.v7.widget.Toolbar>    </RelativeLayout></FrameLayout>

直接运行报错如下：

分析：从log来看，AppCompatActivity已经定义好了一套自己的主题样式，因此直接在代码中设置就会出现这个错误

    protected void initActionBar() {        setSupportActionBar(mToolbar);        mToolbar.setTitle(getTitle());        if (getSupportActionBar() != null) {            getSupportActionBar().setTitle(getTitle());            getSupportActionBar().setDisplayHomeAsUpEnabled(true);        }    }

解决方法：自定义主题样式，代码如下

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">        <!-- Customize your theme here. -->        <item name="colorPrimary">@color/colorPrimary</item>        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>        <item name="colorAccent">@color/colorAccent</item>        <item name="android:windowBackground">@android:color/white</item>        <item name="android:textAllCaps">false</item>        <item name="android:windowActionBar">false</item>        <item name="windowActionBar">false</item>        <item name="windowNoTitle">false</item>        <item name="android:actionMenuTextColor">@android:color/white</item>        <item name="android:actionBarStyle">@style/ToolbarTheme</item>    </style>
