viewpager和drawerlayout一起用的时候注意需要重写DrawerLayout和viewpager
重写drawerlayout
public class HackyDrawerLayout extends DrawerLayout {
public HackyDrawerLayout(Context context) {
super(context);
}
public HackyDrawerLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public HackyDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
private boolean mIsDisallowIntercept = false;
//子View告诉父容器不要拦截我们的事件的(true)
@Override
public void requestDisallowInterceptTouchEvent(boolean disallowIntercept) {
// keep the info about if the innerViews do requestDisallowInterceptTouchEvent
mIsDisallowIntercept = disallowIntercept;
super.requestDisallowInterceptTouchEvent(disallowIntercept);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
// the incorrect array size will only happen in the multi-touch scenario.
if (ev.getPointerCount() > 1 && mIsDisallowIntercept) {
requestDisallowInterceptTouchEvent(false);
boolean handled = super.dispatchTouchEvent(ev);
requestDisallowInterceptTouchEvent(true);
return handled;
} else {
return super.dispatchTouchEvent(ev);
}
}
}
重写viewpager
public class HackyDrawerLayout extends DrawerLayout {
public HackyDrawerLayout(Context context) {
super(context);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
try {
return super.onInterceptTouchEvent(ev);
} catch (IllegalArgumentException e) {
e.printStackTrace();
return false;
}
}
}
