Question

我正在使用我的应用程序的工具栏它在棒棒糖版本中工作正常。但在之前的版本中，应用程序崩溃了。我尝试将样式更改为 Theme.AppCompat.NoActionBar但它没有用。

样式：

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>
<style name="AppThemes" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>

<style name="MyTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:windowBackground">@color/windowBackground</item>
</style>

XmlToolbar：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar         xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

logcat的：

}

    @Override

        return listMessages.get(position);
    }

    @Override

        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        if (view == null) {
            view = inflater.inflate(R.layout.parselist_row, null);
        }

        TextView txtMessage = (TextView) view.findViewById(R.id.message);
        TextView txtTimestamp = (TextView) view.findViewById(R.id.timestamp);

        Message message = listMessages.get(position);

Answer 1

你必须为lollipop下面的设备制作两个styles.xml文件，其他的是用于设备棒棒糖及以上版本的styles.xml（v-21）。 style.xml的示例

<style name="MyAppThemes" parent="MyTheme.Base">
<!-- Customize your theme here. -->
</style>

<style name="MyTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
 <item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="android:windowBackground">@color/windowBackground</item>
</style>

style.xml的样本（v-21）

 <style name="MyAppThemes" parent="MyAppThemes.Base">
<item name="android:windowActionBar">false</item>
<item name="android:colorPrimary">@color/colorPrimary</item>
<item name="android:colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="android:colorAccent">@color/colorAccent</item>
<item name="android:windowBackground">@color/windowBackground</item>
</style>

现在在AndroidMainfest.xml中更改应用程序主题

 android:theme="@style/MyAppThemes">

我希望它能解决你的问题。

Answer 2

您应该在布局中创建toolbar.xml：

<RelativeLayout 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="xxxxxx">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true"
        android:orientation="vertical">

        <include
            android:id="@+id/main_menu_activity_toolbar"
            layout="@layout/XmlToolbar" />

然后给你的活动充气：

mToolbar = (Toolbar) findViewById(R.id.main_menu_activity_toolbar);

修改

在基本应用程序主题中使用NoActionBar

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">  </style>

Answer 3

可能在您的应用AppTheme或“AppThemes”中使用过。您看到您已将父主题设为Theme.AppCompat.Light.DarkActionBar。这意味着您拥有此主题的活动有ActionBar。

只要有ToolBar，就无法使用ActionBar。

只需更改Theme.AppCompat.Light.DarkActionBar

到Theme.AppCompat.Light.NoActionBar。你很高兴。

希望这会对你有所帮助。

<强>更新

将ToolBar设为ActionBar

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

为工具栏膨胀类时出错
