        });

    }
}

Answer 1

尝试将以下数字从0更改为更高的数字

android:layout_width="0dp"

Answer 2

这可能是由于info.hoang8f.widget.FButton库中的一个已知错误。您可以在这里看到问题：https://github.com/hoang8f/android-flat-button/issues/41。

这是因为FButton类在第115行中使用了错误的属性命名：

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

此问题已在另一个分支中得到纠正：https://gitlab.com/RilixTechnology/android-flat-button或https://github.com/jd-alexander/android-flat-button

Answer 3

您使用过的xml文件中的问题

 <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"

       />

此小部件无法膨胀，请尝试对其进行修复或删除。
