如何解决这个二进制XML文件行#8:膨胀类android.support.v7.widget.CardView时出错

Question

当我运行此应用程序时，适配器中有一个卡视图，它给了我一个错误，并且在目标版本高于 27 的某些设备中崩溃。

apply plugin: 'com.android.application'android {
compileSdkVersion 27
buildToolsVersion "27.0.3"
defaultConfig {
applicationId "com.example.umesh"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}}dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'}

这是我的XML文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

android:layout_height="wrap_content"
android:textSize="18sp"

android:maxLines="1"
android:textColor="@color/black"
android:text="" />
<TextView
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:textSize="18sp"

android:maxLines="1"
android:id="@+id/tv_streamername"
android:textColor="@color/black"
android:text="" />
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>

我已经尝试了所有重建和清理项目，当应用程序打开时它仍然崩溃，任何解决方案都会有所帮助。

这是我的卡片视图样式：

<style name="example" parent="Theme.AppCompat.Light" />
<style name="example.CardView">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">@drawable/white_bg_selector</item>
<item name="android:layout_marginLeft">@dimen/cardViewMargin</item>
<item name="android:layout_marginBottom">@dimen/cardViewMargin</item>
<item name="android:layout_marginRight">@dimen/cardViewMargin</item>
<item name="cardElevation">@dimen/cardElevation</item>
</style>

Answer 1

尝试：

<style name="mycardview" parent="CardView">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">@drawable/white_bg_selector</item>
<item name="android:layout_marginLeft">@dimen/cardViewMargin</item>
<item name="android:layout_marginBottom">@dimen/cardViewMargin</item>
<item name="android:layout_marginRight">@dimen/cardViewMargin</item>
<item name="cardElevation">@dimen/cardElevation</item>
</style>
