android - java.lang.System.array 复制错误([CI[CII)V

Question

我遇到一个新问题，可能是由于版本更改，但我不知道。渲染过程中抛出的异常如下:

java.lang.System.array copy([CI[CII)V

异常详细信息记录在 Window > Show View > Error Log 中。

The following classes could not be found: - Edit Text (Change to android.widget.Edit Text, Fix Build Path, Edit XML)

它没有得到编辑文本的类。我从哪里获得/添加它？

Check the "Android version to use when rendering layouts" and make sure you're not using a version that ends in "W" for Android Wear (e.g. API 20: Android 4.4W). I don't believe Wear supports EditText.

In both Android Studio and Eclipse, it's the dropdown with the green android in the layout preview's toolbar. You may want to set it explicitly and not allow the IDE to choose the Android version automatically.
