解决方法
我也一直在寻找一个“完成拖曳”解决方案,以便在地图结束移动之后的时刻检测地图中心.我没有找到它,所以我做了这个简单的实现,工作正常：
private class MyMapView extends MapView {
private GeoPoint lastMapCenter;
private boolean isTouchEnded;
private boolean isFirstComputeScroll;
public MyMapView(Context context,String apiKey) {
super(context,apiKey);
this.lastMapCenter = new GeoPoint(0,0);
this.isTouchEnded = false;
this.isFirstComputeScroll = true;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN)
this.isTouchEnded = false;
else if (event.getAction() == MotionEvent.ACTION_UP)
this.isTouchEnded = true;
else if (event.getAction() == MotionEvent.ACTION_MOVE)
this.isFirstComputeScroll = true;
return super.onTouchEvent(event);
}
@Override
public void computeScroll() {
super.computeScroll();
if (this.isTouchEnded &&
this.lastMapCenter.equals(this.getMapCenter()) &&
this.isFirstComputeScroll) {
// here you use this.getMapCenter() (e.g. call onEndDrag method)
this.isFirstComputeScroll = false;
}
else
this.lastMapCenter = this.getMapCenter();
}
}
就这样,我希望它有帮助！ O /
