implementation 'com.android.support:appcompat-v7:28.0.0'
我没有在AppCompatTextView标记中使用android:text。在ResultActivity.java中，您可以看到一个私有的void viewpage（）。有很多数据（文本）关于AppCompatTextView。这无关紧要。您的gradle文件中是否有我的答案中所示的正确依赖项？我的CompileSDK版本是30。因此，当我将实现“com.android.support:appcompat-v7:28.0.0”放入时，文本颜色变为红色。（错误）所以，我把实现放在了'com.android.support:appcompat-v7:30.0.0'。此外，我使用了两个viewPager.MainActivity.java使用viewPager。我也想使用resultivity.java。哦..我真的很抱歉…谢谢你的努力！你会很好的！
