我有一个垂直的LinearLayout,其中一个项目是ImageView使用Picasso加载的.我需要将图像的宽度提升到整个设备宽度,并显示图像的中心部分被固定高度(150dp)裁剪.我目前有以下代码:

Picasso.with(getActivity()) 
    .load(imageUrl) 
    .placeholder(R.drawable.placeholder) 
    .error(R.drawable.error) 
    .resize(screenWidth, imageHeight)
    .centerInside() 
    .into(imageView);

我应该把哪个值成screenWidth和imageHeight(= 150dp)？

今天早上我遇到了Android Studio的问题,每当我打开它时,我都会收到以下错误.

我尝试删除Android Studio并进行全新安装.删除所有首选项文件夹.删除并重新下载项目的存储库.创建一个新项目.所有这些仍然以此错误显示结束.无论我增加内存有多高,它仍然会遇到这个问题.

我检查了Activity Monitor,它实际上只使用了524mb的内存.有没有人有什么建议？

我将要尝试的下一件事是使用旧版本的Android工作室.除此之外,我不确定除了干净安装操作系统之外还有什么可做的,并希望最好.

更新: 无法找到解决此问题的方法,并且必须执行干净的OSX重新安装.

最近我们开始为我们的Android应用项目添加测试.我们开始使用Robolectric但最近不得不将其解决,而是仅使用普通测试,因为我们遇到了Couchbase的问题.在添加Couchbase之前,我们的测试在与Roblectric一起运行时运行良好.

从一个没有Couchbase的新分支机构中,我正在拔出Robolectric并转换到使用标准连接测试.我已经退出了Robolectric,我的所有测试都再次运行.HTML测试报告正确生成我们期望的所有结果.如果测试失败,控制台会准确反映哪个测试失败以及原因.

我们遇到的问题是,即使所有测试都再次运行(并通过),测试也会失败,并显示以下消息:

com.android.builder.testing.ConnectedDevice > hasTests[Nexus 4 - 4.4.4] FAILED 
No tests found.

* What went wrong:

* Try:

运行--stacktrace我可以看到它肯定来自该库.

我最近从Eclipse迁移到了Android Studios.我通过eclipse使用Proguard我的应用程序,现在我已经移动我遇到以下错误.

错误:

我在我的应用程序中解析了1.5.1并且一切正常,但是当我导出到APK时,我得到:
