java.lang.IllegalArgumentException：DrawerLayout 必须使用 MeasureSpec.EXACTLY 进行测量

Question

我搜索了很多问题，但没有一个答案对我有帮助！我将一个带有导航抽屉的活动连接到一个片段......但我从这个错误开始！感谢您的帮助！

java.lang.IllegalArgumentException: DrawerLayout must be measured with MeasureSpec.EXACTLY.

Answer 1

正如错误所说：将DrawerLayout 宽度更改为某个确定值，例如240dp 而不是match_parent

查看源代码：

 if (widthMode != MeasureSpec.EXACTLY || heightMode != MeasureSpec.EXACTLY) {
            if (isInEditMode()) {
                // Don't crash the layout editor. Consume all of the space if specified
                // or pick a magic number from thin air otherwise.
                // TODO Better communication with tools of this bogus state.
                // It will crash on a real device.
                if (widthMode == MeasureSpec.AT_MOST) {
                    widthMode = MeasureSpec.EXACTLY;
                } else if (widthMode == MeasureSpec.UNSPECIFIED) {
                    widthMode = MeasureSpec.EXACTLY;
                    widthSize = 300;
                }
                if (heightMode == MeasureSpec.AT_MOST) {
                    heightMode = MeasureSpec.EXACTLY;
                }
                else if (heightMode == MeasureSpec.UNSPECIFIED) {
                    heightMode = MeasureSpec.EXACTLY;
                    heightSize = 300;
                }
            } else {
                throw new IllegalArgumentException(
                        "DrawerLayout must be measured with MeasureSpec.EXACTLY.");
            }
        }

我遇到了类似的问题，在调查过程中我发现这是因为HorizontalScrollVIew 在我的视图层次结构中，尝试使用它
