找不到类'android.widget.ThemedSpinnerAdapter'[Android Studio] [英] Could not find class 'android.widget.ThemedSpinnerAdapter' [Android Studio]

问题描述

当我尝试在API 21之前的设备上运行我的应用程序时，出现了这个奇怪的错误:

I am getting this weird error when I try to run my app on a pre API 21 device:

I/Choreographer: Skipped 39 frames!  The application may be doing too much work on its main thread.

实际上我没有收到ANR，或者不幸的是，您的应用程序停止运行，该应用程序无提示地退出了主要活动.

Actually I don not get a ANR or Unfortunately your app stopped working, the app silently exits to the Main Activity.

我在应用程序中没有使用任何重量级图像，只是一个包含四个微调器的页面.

I am not using any heavyweight images in my application, just a page with a four spinners.

尤其是，该行以红色突出显示:

In particular, this line is highlighted in red:

E/dalvikvm: Could not find class 'android.widget.ThemedSpinnerAdapter', referenced from method android.support.v7.widget.AppCompatSpinner$DropDownAdapter.<init>

但是，由于我没有使用eclipse，所以我确定我可以使用gradle正确导入:

However as I am not using eclipse, I am sure I have proper imports using gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "projects.test.com.webviewtest"
        minSdkVersion 14
        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 'com.android.support:recyclerview-v7:23.1.1'
}

推荐答案

在我看来，这是通过删除布局XML文件中的android:tint="?attr/colorControlNormal"来解决的……也许对其他人有帮助.

In my situation this was resolved by removing the use of android:tint="?attr/colorControlNormal" within the layout XML file... Maybe this helps others.
