在使用DrawerLayout布局时将其宽高设置为自动填充屏幕后便会出现
DrawerLayout must be measured with MeasureSpec.EXACTLY.异常。
关于这个异常，一般来说给出确切的宽高大小即可，
例如：layout_width=“340dp”

问题是很多时候没有那么合适的的时候，就只能重写onMeasure方法，就像下面这样即可：

public class MyDrawerLayout extends DrawerLayout {public MyDrawerLayout(Context context) {super(context);}public MyDrawerLayout(Context context, AttributeSet attrs) {super(context, attrs);}public MyDrawerLayout(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {widthMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);heightMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY);super.onMeasure(widthMeasureSpec, heightMeasureSpec);}}
