渲染问题，我该如何解决？

Question

I have a problem with the preview of my app.

In the log file i have a few errors :

This is a group project but I am the only one encountering this problem. I just downloaded Android Studio so I did not touch anything in the settings.

Any idea?

Answer 1

在build.gradle添加约束布局依赖build.gradle

implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

Answer 2

Just click the blue text that prompt in your console

or try to add these into your gradle (app level)

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'

And you can update them to latest version if Android Studio tells you there's a new version.
