Android滑动冲突解决方案
外部拦截法
重写父View onInterceptTouchEvent方法就行：
float latestX;
float latestY;
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
boolean isIntercept = false;
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
isIntercept = false;
break;
case MotionEvent.ACTION_MOVE:
float dx = Math.abs(ev.getRawX() - latestX);
float dy = Math.abs(ev.getRawY() - latestY);
if (dx > dy) {
isIntercept = true;
} else {
isIntercept = false;
}
break;
case MotionEvent.ACTION_UP:
isIntercept = false;
break;
}
latestX = ev.getRawX();
latestY = ev.getRawY();
return isIntercept;
}内部拦截法
父View重写onInterceptTouchEvent方法：
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
boolean isIntercept = false;
if (ev.getAction() == MotionEvent.ACTION_DOWN) {
isIntercept = false;
} else {
isIntercept = true;
}
return isIntercept;
}然后子View重写dispatchTouchEvent方法：
float latestX;
float latestY;
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_MOVE:
float dx = Math.abs(ev.getRawX() - latestX);
float dy = Math.abs(ev.getRawY() - latestY);
if (dx > dy) {
getParent().requestDisallowInterceptTouchEvent(false);
}
break;
case MotionEvent.ACTION_UP:
break;
latestX = ev.getRawX();
latestY = ev.getRawY();
return super.dispatchTouchEvent(ev);
