Question

我尝试按照本指南http://antonioleiva.com/material-design-everywhere/使用AppCompat v21实现工具栏但是我无法在KitKat或Lollipop上启动并获得相同的错误消息（如下所示）。我完全相信我已经正确设置了主题，但我在这一点上陷入困境并且已经持续了一天多。我没有成功搜索解决方案，所以现在我要求一些帮助。谢谢！

这是我的/res/values/themes.xml

<resources>

<style name="CETheme" parent="AppTheme" ></style>
<style name="AppTheme" parent="Theme.AppCompat">
    <item name="android:colorPrimaryDark">@color/MidnightBlue</item>
    <item name="android:colorAccent">@color/LightYellow</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>

</style>

这是我的/res/values-v21/themes.xml

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

    <item name="android:windowContentTransitions">true</item>
    <item name="android:windowAllowEnterTransitionOverlap">true</item>
    <item name="android:windowAllowReturnTransitionOverlap">true</item>
    <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
    <item name="android:windowSharedElementExitTransition">@android:transition/move</item>

    <item name="android:colorPrimary">@color/ChaosBlue</item>
    <item name="android:colorPrimaryDark">@color/MidnightBlue</item>
    <item name="android:colorAccent">@color/LightYellow</item>
    <item name="android:statusBarColor">@color/ChaosBlue</item>

</style>

以下是我的DrawerActivity.java中引发错误的片段：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setActionBarIcon(R.drawable.ic_drawer);

正在调用BaseActivity.java的片段：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(getLayoutResource());
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    if (toolbar != null) {
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }
}

最后这是AndroidManifest.xml的片段

<application
    android:allowBackup="true"
    android:icon="@drawable/logo"
    android:label="@string/app_name"
    android:theme="@style/CETheme"
    android:name="android.support.multidex.MultiDexApplication">

Answer 1

我终于发现了原因，在我的AndroidManifest中，我为DrawerActivity设置了一个主题，这导致了错误。

Answer 2

尝试使用 colorPrimaryDark 替换 android：colorPrimaryDark ，并在res / values /中使用 colorAccent 替换 android：colorAccent 的themes.xml。

尝试使用AppCompat v21实现工具栏
