Missing styles. Is the correct theme chosen for this layout?
Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.

NOTE: This project contains resource errors, so aapt did not succeed, which can cause rendering failures. Fix resource problems first.

Failed to find style 'textViewStyle' in current theme
android.content.res.Resources$NotFoundException
Couldn't find theme resource ?android:attr/textAppearanceLarge for the current theme
Exception details are logged in Window > Show View > Error Log
The following classes could not be found:
- TextView (Change to android.widget.TextView, Fix Build Path, Edit XML)

选择一个主题，比如DeviceDefault.Light
