Question

我正在使用AppCompatActivity库来支持所有设备。在提升android-support-v7-appcompat库后，我面临问题。但我在运行期间遇到错误。我正在使用eclipse studio来编写android项目代码。任何帮助将不胜感激。

以下是我的错误，我不知道我哪里出错。

Answer 1

即使是一个老问题，但我遇到了同样的问题，我只是通过清理重建项目来修复它

建设 - ＆GT;清洁项目

然后运行项目

Answer 2

ActionBar在材料设计中用作工具栏。所以添加没有操作栏的主题并使用以下是在xml中使用工具栏。

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:iosched="http://schemas.android.com/apk/res-auto"
style="@style/HeaderBar"
iosched:theme="@style/ActionBarThemeOverlay"
iosched:popupTheme="@style/ActionBarPopupThemeOverlay"
android:id="@+id/toolbar_actionbar"
iosched:titleTextAppearance="@style/ActionBar.TitleText"
iosched:contentInsetStart="?actionBarInsetStart"
android:layout_width="match_parent"
android:layout_height="?actionBarSize" />

Answer 3

我找到了可能错误的解决方案，我必须添加implements的{{1}}覆盖方法。下面是我修复它的代码。

appCompatActivity

我可以添加状态栏以及操作栏。：）

Answer 4

您是否曾尝试在gradle文件中添加此代码示例？

   android {
         configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
    all*.exclude group: 'com.android.support', module: 'support-annotations'
} }

使用AppCompatActivity而不是Actionbar时出现运行时错误
