Question

在将问题标记为重复之前，我已经检查了其他答案，但没有任何效果。该应用程序适用于Android＆gt; = 5.0，但在Android 4.4.2和其他Android 4.x设备上可能会失败。

这是发生崩溃的地方：

 @Override
    public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
       View itemView = LayoutInflater.from(context).inflate(itemLayout, parent, false);
       ..........................

build.gradle

android {
    compileSdkVersion 23
    buildToolsVersion ANDROID_BUILD_TOOLS

defaultConfig {
    minSdkVersion 16
    targetSdkVersion ANDROID_TARGET_SDK
.......................
}


dependencies {
 compile 'com.android.support:appcompat-v7:23.1.0'
 compile 'com.android.support:design:23.1.0'
 compile 'com.android.support:recyclerview-v7:23.1.0'
 compile 'com.github.bumptech.glide:glide:3.5.2'
 .......................
}

我似乎无法弄清楚为什么会这样，这让我疯狂。我非常感谢任何帮助。

Answer 1

在花了两个愚蠢的日子搞清楚是什么问题后，我想出了原因。：使用属性作为xml drawable中颜色的引用。在API＆lt; 21上，你不能使用attrs在xml drawable中着色。所以唯一的方法是使用颜色资源的引用（@ color / YOURS_COLOR）或使用#RGB格式。所以如果你想使用xml drawable和主题依赖颜色，你应该为每个主题创建一个drawable;

解决方案：如果有人遇到他的异常，你应该抓住它并在变量窗口中查看它的原因，因为错误消息更明确的地方。

我将相对布局的背景从@ drawable / selectable_background.xml更改为其他颜色，现在一切正常。

仅在Android 4.X
