Question

我绝对是Android的初学者。现在我正在学习如何设计Android应用程序。所以现在我正在尝试使用CircleImageView。我用gradle安装它。但是当我在布局文件中使用它时，它会抛出错误。

这是我的带有CircleImageView的xml布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:orientation="vertical"
    android:gravity="bottom">

    <CircleImageView
        android:src="@drawable/calendar"
        android:layout_width="50dp"
        android:layout_height="50dp" />

    <TextView
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textStyle="bold"
        android:text="Your to-do list"
        android:textColor="@android:color/white"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>
</LinearLayout>

这是我在Gradle中使用compile安装CircleImageView的方法：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.waiyanhein.todo.todo"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'de.hdodenhof:circleimageview:1.3.0'
}

但是当我运行它时，它会抛出错误。

这是Logcat：

我的代码出了什么问题，是否正确使用它？

Answer 1

xml中的

将CircleImageView替换为de.hdodenhof.circleimageview.CircleImageView

link

最终代码

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimaryDark"
        android:padding="16dp"
        android:theme="@style/ThemeOverlay.AppCompat.Dark"
        android:orientation="vertical"
        android:gravity="bottom">

        <de.hdodenhof.circleimageview.CircleImageView
            android:src="@drawable/calendar"
            android:layout_width="50dp"
            android:layout_height="50dp" />

        <TextView
            android:layout_marginTop="10dp"
            android:layout_marginBottom="10dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textStyle="bold"
            android:text="Your to-do list"
            android:textColor="@android:color/white"
            android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>
    </LinearLayout>

Answer 2

在您的xml更改de.hdodenhof.circleimageview.CircleImageView到

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimaryDark"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:orientation="vertical"
    android:gravity="bottom">

    <de.hdodenhof.circleimageview.CircleImageView
        android:src="@drawable/calendar"
        android:layout_width="50dp"
        android:layout_height="50dp" />

    <TextView
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textStyle="bold"
        android:text="Your to-do list"
        android:textColor="@android:color/white"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>
</LinearLayout>
