java - 如何解决: Error inflating class android. support.v7.widget.CardView

Question

我对这个错误感到非常沮丧。我完成了我的项目并在我的 Android 4.4.2 版设备上运行，它运行成功，然后我成功上传到 Playstore 并再次从 Playstore 安装，但仍然运行良好......

但后来我从 friend 那里收到了很多崩溃报告。然后我借用了 Android 版本 6.0.1 的 friend 设备，我从 Android Studio 运行应用程序，应用程序在 Splashactivity 启动后突然崩溃。 Splashactivity 成功启动然后在打开 Mainactivity 之前我使用 fragment 容器加载 5-6 个 fragment ...它崩溃了。

下面是我的错误日志报告

我的构建 gradle 文件是

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.nepalpolice.cdp"

        targetSdkVersion 26

        versionName "5.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    dexOptions {
        jumboMode true
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation 'com.google.firebase:firebase-storage:11.8.0'

        implementation files('libs/libGoogleAnalyticsServices.jar')


    }
    apply plugin: 'com.google.gms.google-services'
}

图像文件是

我的主要 fragment 是

  public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_main, container, false);
    news   = (ImageView) view.findViewById(R.id.news);
    notice   = (ImageView) view.findViewById(R.id.notice);

我该如何解决这个问题......我也关注了许多其他帖子，但也没有帮助。 提前致谢

使用

app:backgroundTint="@drawable/megaphone"

代替这个

 android:backgroundTint="@drawable/megaphone"

试试这个

<android.support.v7.widget.CardView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                app:layout_columnWeight="1"
                app:layout_rowWeight="1"
                android:layout_marginBottom="0dp"
                android:layout_marginLeft="0dp"
                android:layout_marginRight="0dp"
                app:cardElevation="8dp"
                app:cardCornerRadius="8dp"
                app:backgroundTint="@drawable/megaphone"
