尝试将下面的值从0更改为更高的数字

android:layout_width="0dp"

It's probably because of a known bug in info.hoang8f.widget.FButton library. You can see the issue here: https://github.com/hoang8f/android-flat-button/issues/41 .

It is because the FButton class is using an incorrect attribute naming in line 115 : 

else if (attr == R.styleable.FButton_buttonColor) {
  ...
}

this problem has been corrected in another fork: https://gitlab.com/RilixTechnology/android-flat-button or https://github.com/jd-alexander/android-flat-button

problem in you xml file where you used 

 <info.hoang8f.widget.FButton
        android:id="@+id/btnSignUp"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        android:layout_weight="1"
        android:text="Sign Up"
        android:textColor="@android:color/white"
        app:buttonColor="@color/btnSignUp"
        app:shadowColor="@android:color/black"
        app:shadowEnabled="true"
        app:shadowHeight="5dp"

       />

this Widget can't inflate, try to fix it or Remove.
