如何解决：错误膨胀类android.support.v7.widget.CardView

标签： java android android-layout android-studio android-fragments

我对这个bug感到非常沮丧。我完成了我的项目并在我的Android 4.4.2版本的设备上运行，它运行成功，然后我成功上传到Playstore并再次从Playstore安装，但仍然工作正常......

但后来我收到了很多朋友的崩溃报告。然后我借用了Android版6.0.1的朋友设备，我从Android Studio运行应用程序，应用程序在Splashactivity启动后突然崩溃。 Splashactivity开始成功然后在打开Mainactivity之前，我使用片段容器加载5-6片段......它崩溃了。

以下是我的错误日志报告

                </LinearLayout>

            </android.support.v7.widget.CardView>


  </LinearLayout>




</ScrollView>


</RelativeLayout>

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"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 5
        versionName "5.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }
    dexOptions {
        jumboMode true
    }

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





dependencies {
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation 'com.google.firebase:firebase-storage:11.8.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation("com.github.bumptech.glide:glide:4.6.1") {
        exclude group: "com.android.support"
        implementation 'com.android.support:appcompat-v7:26.+'

        implementation 'com.google.firebase:firebase-messaging:11.8.0'
        implementation 'com.google.gms:google-services:3.1.0'
        implementation 'com.android.support:design:26.+'

        implementation files('libs/libGoogleAnalyticsServices.jar')


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

和图像文件是 Error log Report

我的主要片段是

  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);

我如何解决这个问题.....我也接受了许多其他帖子，但它也没有帮助。 提前致谢

使用

app:backgroundTint="@drawable/megaphone"

而不是这个

 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"

您已在滑行中实现了所有依赖项。尝试下面的gradle

Gradle：

dependencies {
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation 'com.google.firebase:firebase-storage:11.8.0'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation("com.github.bumptech.glide:glide:4.6.1") {
        exclude group: "com.android.support" 
     }
        implementation 'com.android.support:appcompat-v7:26.+'
        implementation 'com.android.support:support-v4:26.+'
        implementation 'com.android.support:cardview-v7:26.+'
        implementation 'com.android.support:recyclerview-v7:26.+'
        implementation 'com.google.firebase:firebase-messaging:11.8.0'
        implementation 'com.google.gms:google-services:3.1.0'
        implementation 'com.android.support:design:26.+'
        implementation 'de.hdodenhof:circleimageview:2.2.0'

        implementation 'com.theartofdev.edmodo:android-image-cropper:2.5.1'
        implementation 'com.android.support:gridlayout-v7:26.+'
        implementation 'com.github.clans:fab:1.6.2'
        testCompile 'junit:junit:4.12'
        implementation 'com.google.android.gms:play-services-maps:11.8.0'
        implementation 'com.google.firebase:firebase-firestore:11.8.0'
        implementation 'id.zelory:compressor:2.1.0'
        implementation files('libs/libGoogleAnalyticsServices.jar')

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

在查看您的// Replace the variables in this block with real values. var address = 'database_IP_address'; var user = 'user_name'; var userPwd = 'user_password'; var db = 'database_name'; var dbUrl = 'jdbc:mysql://' + address + '/' + db' integrated security = ssip; // Read up to 1000 rows of data from the table and log them. function readFromTable() { var conn = Jdbc.getConnection(dbUrl, user, userPwd); var start = new Date(); var stmt = conn.createStatement(); stmt.setMaxRows(1000); var results = stmt.executeQuery('SELECT * FROM entries'); var numCols = results.getMetaData().getColumnCount(); while (results.next()) { var rowString = ''; for (var col = 0; col < numCols; col++) { rowString += results.getString(col + 1) + '\t'; } Logger.log(rowString) } results.close(); stmt.close(); var end = new Date(); Logger.log('Time elapsed: %sms', end - start); }代码后，我发现您忘记声明导致此xml的ID news和notice。

解决方案：将这些字段声明为所需的android.view.InflateException＆＃39;

尝试使用app:cardBackgroundColor相反，我认为tint无效CardView

OR

测试问题，尝试用任何颜色替换@drawable/megaphone，可能是megaphone
