android - 膨胀类 android.support.v7.widget.Toolbar 时出错

Question

我已将我的应用程序从使用操作栏移至工具栏，但最终出现错误(底部的完整错误)。我的代码:

我的 Activity :

public class MapsActivity extends ActionBarActivity implements LocationListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        ...
        mDrawerLayout.setDrawerListener(mDrawerToggle);

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

    if (toolbar != null)
    {
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
        getSupportActionBar().setElevation(0); // or other
    }

        ...
    }
...
}

v21/style.xml

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- your app's theme inherits from the Material theme -->
    <style name="AppTheme" parent="android:Theme.Material.Light.DarkActionBar">
        <item name="windowActionBar">false</item>
        <item name="android:windowNoTitle">true</item>
        <!-- Main theme colors -->
        <!--   your app branding color for the app bar -->
        <item name="android:colorPrimary">@color/primary</item>
        <!--   darker variant for the status bar and contextual app bars -->
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        <item name="android:navigationBarColor">@color/primary</item>

        <!--   theme UI controls like checkboxes and text fields -->
        <item name="android:colorAccent">@color/accent</item>
    </style>
</resources>

样式.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
</style>

</resources>

梯度依赖

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services:6.5.87'
    compile 'com.android.support:appcompat-v7:21.0.3'
}

我的 XML 布局(由答案更改后)

LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    />

<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        </RelativeLayout>

<!-- The navigation drawer -->
<RelativeLayout
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#111">s


    </RelativeLayout>

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

下面的错误给出了答案:

Answer 1

将您的父主题替换为@style/Theme.AppCompat.NoActionBar

<style name="AppTheme" parent="@style/Theme.AppCompat.NoActionBar">
   <item name="windowActionBar">false</item>
   <item name="android:windowNoTitle">true</item>
</style>
