Question

我正在制作一个我想使用CardView的应用程序。

我下载了开源项目并根据我的需要应用更改，但我收到错误：

Error:(3) Error parsing XML: unbound prefix

Error:Execution failed for task ':app:processDebugResources'.
com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\Andrew\AppData\Local\Android\sdk\build-tools\21.1.2\aapt.exe'' finished with non-zero exit value 1

这是我的xml：

<LinearLayout

xmlns:tools="http://schemas.android.com/tools"


android:orientation="vertical"
android:layout_width="match_parent"

                </LinearLayout>
            </com.example.ahsankhan.smsburst.test>

</FrameLayout>

<!-- Button bar -->
<LinearLayout
    android:layout_height="48dp"
    android:background="@color/theme_primary"
    android:layout_gravity="bottom"
    android:layout_width="match_parent">

    <Button
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:background="?photoItemForeground"
        android:text="@string/decline"
        android:textColor="#8fff"
        android:textSize="@dimen/text_size_medium"
        android:textStyle="@integer/font_textStyle_medium"
        android:fontFamily="@string/font_fontFamily_medium"
        android:textAllCaps="true"
        android:id="@+id/button_decline" />

    <Button

        android:fontFamily="@string/font_fontFamily_medium"
        android:textAllCaps="true"
        android:textColor="#fff" />

</LinearLayout>
</LinearLayout>

这是我的build.gradle文件：

apply plugin: 'com.android.application'

android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.example.ahsankhan.smsburst"
    minSdkVersion 9
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 
file('proguard-project.txt')
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}

您需要在父布局中添加android xmlns属性，如：

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:iosched="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    ...

错误：（3）解析XML时出错：未绑定的前缀
