标签： android performance android-layout android-cardview android-scrollview

以下是我的代码。代码格式为

 <ScrollView>
    <LinearLayout>
         <CardView>  <LinearLayout> <TextView> <ImageView> </LinearLayout> </CardView>
         .  //5 more card views similar to this of same Content.
         .
    </LinearLayout>
</ScrollView>

应用程序在手机上运行时崩溃。 logcat读取

我还添加了CardView依赖项， 尝试使用嵌套的Scroll视图和 使用了Layout_height =＆＃34; wrap_content＆＃34;在cardView但无济于事。 我还没有在MainActivity.Java中添加任何内容。

请指明我的错误以及我必须遵循的其他方式。

我的完整代码如下： -
