android地图：拖拽完成后如何确定地图中心

解决方法

@H_616_7@ 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 /
