您好亲爱的stackoverflower,

在我的项目中,我正在使用新的"android设计库".问题是,有一个运行时异常说(我试图创建一个FloatingButton):

 java.lang.RuntimeException: Failed to resolve attribute at index 6
        at android.content.res.TypedArray.getColorStateList(TypedArray.java:426)
        at android.support.design.widget.FloatingActionButton.<init>(FloatingActionButton.java:91)
        at android.support.design.widget.FloatingActionButton.<init>(FloatingActionButton.java:79)
        at android.support.design.widget.FloatingActionButton.<init>(FloatingActionButton.java:75)

我弄清楚了哪个属性无法解决:

<style name="Widget.Design.FloatingActionButton" parent="android:Widget">
    <item name="android:background">@drawable/fab_background</item>
    <item name="backgroundTint">?attr/colorAccent</item>  **!! this one is missing !!**
    <item name="fabSize">normal</item>
    <item name="elevation">@dimen/fab_elevation</item>
    <item name="pressedTranslationZ">@dimen/fab_translation_z_pressed</item>
    <item name="rippleColor">?attr/colorControlHighlight</item>
    <item name="borderWidth">@dimen/fab_border_width</item>
</style>

它位于android-design-library中的res/values/styles/styles.xml中

我在这篇文章中读过API lvl应该是21+.但是由于设计库支持API 7+,实际上这应该不是问题.

值得一提的是,我没有将设计库包含为这样的gradle依赖:

 compile 'com.android.support:design:22.2.0'

我正在手动将库添加到项目中,因为Jenkins服务器无法访问Internet.我已将support-v4库更新为21.2.0,同时包含并更新了appcompat support-v7.

这是android-design-library gradle文件:

android {
compileSdkVersion 21
buildToolsVersion "21.1.2"

defaultConfig {
    minSdkVersion 17
    targetSdkVersion 21
}

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

我不断收到这个错误,当我试图setErrorEnabled在我的textInputLayout:

这是场景 - 我有一个textInputLayout内部popupwindow.这是popupwidow中的代码.

public class NamePopUp extends PopupWindow {

    android.support.v7.widget.AppCompatEditText name;
    TextInputLayout nameInput;


    public NamePopUp(final Context context) …

我有一个非常简单的布局,我使用Design Support Library中的新android.support.design.widget.TextInputLayout视图

<android.support.design.widget.TextInputLayout
    android:id="@+id/til"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <EditText
        android:id="@+id/textDialog"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="First Name"/>
</android.support.design.widget.TextInputLayout>

在膨胀时,我得到例外:
