解决这个问题我很累。应用程序不执行它总是向我显示此错误二进制XML文件第26行：膨胀类EditText时出错。我不知道如何解决此问题。 这是我的activity_members.xml

您需要在布局文件中设置EditText的宽度和高度，但不能将这些属性设置为0dp。如果要根据屏幕尺寸进行设置，则可以在xml中使用layout_weight。Here you can know about layout_weight usage
如果在布局中使用constraintLayout，则可以看到此链接。 Responsive layout designing with constraint layout
