我正在尝试查看包含一些自定义视图的xml布局的预览(没有什么复杂的...主要是包装器).我收到以下错误:

它们只是简单的.jsp文件......不是J2EE或Web项目的一部分.问题似乎是每当我尝试添加标签时...但它似乎并不总是导致问题.这似乎很有气质.
认为它是各种参考问题？Eclipse中的自动完成问题？
我看到其他人对此有疑问,但我无法找到明确的解决方案.任何帮助将不胜感激!
我想做点什么
<TextViewPlus
android:id="@+id/settings_title_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="@string/settings />
代替
<com.my.really.super.long.package.name.that.wont.autocomplete.TextViewPlus
android:id="@+id/settings_title_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="@string/settings />
我想我可以把自定义视图放在(默认)包中,但这似乎是一个坏主意.(编辑:经过测试,它无论如何都不起作用)是否有"好"的方法来做到这一点？
随着对Gradle构建系统的更改,我注意到在.idea/libraries项目目录中添加了一堆*.xml文件.我假设这是Android Studio/IntelliJ将库链接到项目的方式.
可以/建议将.idea/libraries添加到.gitignore吗？由于gradle处理所有依赖项,我认为这些都会被添加/覆盖.希望得到一些确认.
我在Travis构建服务器上的Robolectric测试中获得了以下NPE,我很难找到原因.我无法在本地重现此问题.
有人知道是什么原因导致onServiceConnected被调用？这可能有助于我找出问题所在.据我所知,这是Google Play服务 - Google Analytics问题.

public abstract class Presenter<T extends BaseView> {
@Inject T mView;
public void showLoadingIndicator() {
mView.showLoading();
}
}
(示例模块)
public class MyModule {
private MyView mView; //extends BaseView
public MyModule(MyView view) {
mView = view;
}
@Provides
public BaseView provideView() {
return mView;
}
}
然后使用上面的模块创建一个对象图并将视图注入演示者？
我的尝试没有奏效(通常会得到"未知类'T'"的错误).我不确定我的配置是否错误或者这是否是不受支持的功能.
在更新到Gradle Build Tools 2.1.3和Gradle 2.14.1之后,我在Android项目中看到以下错误.它在我运行应用程序时立即发生.我该如何解决？

我正在尝试添加android:lineSpacingMultipliertextAppearance样式（android:textAppearance），但无法正常工作。难道我做错了什么？
TextAppearance样式：
<style name="TextAppearance.Body1" parent="TextAppearance.AppCompat.Body1">
<item name="android:lineSpacingMultiplier">1.25</item>
</style>
使用方式：
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is body 1\nThis is body 1"
android:textAppearance="TextAppearance.Body1"
/>
我在Java中有一个命名参数,我按以下方式注入:
@Inject @Named("io")
Scheduler ioScheduler;
我怎么在Kotlin这样做？
