Question

我有一个扩展AppCompatActivity的主要活动，当App启动时，立即执行AsyncTask并显示一个对话窗口忙碌的指标。在应用程序启动时运行时崩溃，我收到以下logcat错误。

我还提到了一些帖子，我尝试了一个建议的解决方案，比如添加以下行

<item name="windowActionBar">false</item>

到styles.xml，但它没有解决问题

styles.xml

<resources>

<!-- Base application theme. -->
<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>
</style>

对话框的布局

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

<TextView
    android:id="@+id/act_main_tv_phase_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:text="task in progress"
    android:textAppearance="?android:attr/textAppearanceLarge" />

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/act_main_tv_phase_name"
    android:layout_centerHorizontal="true"
    android:minWidth="56dp">

    <ProgressBar
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:id="@+id/act_main_pb_busy_indicator"/>
</FrameLayout>

logcat的：

Answer 1

 <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowContentOverlay">@null</item>

    <item name="actionBarStyle">@style/Widget.AppTheme.ActionBar</item>

</style>


<style name="Widget.AppTheme.ActionBar" parent="Widget.AppCompat.ActionBar.Solid">
    <!-- action bar background -->
    <item name="background">@color/actionBar</item>
</style>

第一种风格是你的app风格，第二种是app-compat。

Answer 2

要解决您的问题，您有两种选择：

第一种方法是使用Theme.AppCompat.NoActionBar作为父主题。这可能是正确的。

如果您不能这样做（可能需要支持操作栏而没有操作栏），您应该执行以下操作：

<style name="MyTheme" parent="Theme.AppCompat">
    ...
</style>

<style name="MyTheme.NoActionBar">
    <!-- Both of these are needed -->
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

如何使Appcompat支持当前主题
