我使用dispatchTouchEvent通过以下代码做出滑动手势
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
// TODO Auto-generated method stub
boolean result = super.dispatchTouchEvent(ev);
// disable the gesture in this screen because we have
return gDetector.onTouchEvent(ev);
}
我想使用SignatureView捕获客户签名
https://github.com/CoatedMoose/CustomViews/blob/master/library/src/com/coatedmoose/customviews/SignatureView.java
所以我想在用户单击SignatureView时禁用滑动手势,我该怎么做?
最佳答案
我对SignatureView
项目不熟悉,但是对于常规的GesturDetector
,您可以像下面这样将事件传递给GestureDetector
,仅当它在其“目标” View
范围内时:
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
boolean result = super.dispatchTouchEvent(ev);
if (inSignatureArea(ev)) {
return gDetector.onTouchEvent(ev);
}
else {
return result;
}
}
public boolean inSignatureArea(MotionEvent ev) {
float eventX = ev.getX();
float eventY = ev.getY();
return (eventX > signatureArea.getX() && eventX < (signatureArea.getX() + signatureArea.getWidth())) ;
// && (same thing for Y and height);
}
您应该能够使其适应您的需求。
