Java 安卓studio 3.0渲染“；在呈现过程中引发的异常”；及；“测量误差”；

在我将Android studio升级到3.0版后，我遇到了一些渲染问题

我尝试过像这样更改SDK版本，但仍然没有成功

我的JDK版本是1.8，下面是我的一些gradle信息

compileSdkVersion 26

defaultConfig {
    applicationId "com.example.wheathermaster"
    minSdkVersion 19
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

我还尝试了“清理项目”和“使缓存无效/重新启动”，但都不起作用

下面是我的错误消息：

渲染期间引发异常

我也有同样的问题。我将font.xml更改为旧的，并解决了这个问题。

我不知道是什么字体导致了这个错误，但这对我来说很有效。

很抱歉回答得太晚，但是将IDE AndroidS更新到3.2应该可以解决您的问题。干杯！：）

只需关闭Android Studio，删除

.Android

和

.gradle

文件，然后再次打开Android Studio。问题应该解决。

我最终通过将Android studio更新为3.2解决了这个问题。在完成当前工作后，我将尝试更改font.xml。我最终通过将Android studio更新为3.2解决了这个问题。在完成当前工作后，我将尝试更改font.xml。
