java - 获取引发监听器的对象

Question

我将此监听器放在多个 swipelistview 上

BaseSwipeListViewListener myBaseSwipeListViewListener = new BaseSwipeListViewListener() {
            @Override
            public void onOpened(int position, boolean toRight) {
            //Here I need the calling swipelistview
            }
}

与

swipelistview0.setSwipeListViewListener(myBaseSwipeListViewListener);
swipelistview1.setSwipeListViewListener(myBaseSwipeListViewListener);
swipelistview2.setSwipeListViewListener(myBaseSwipeListViewListener); //and so on

如何获得调用的 swipelistview ？

Answer 1

好吧，我不确定我是否明白你的意思，但是如果向你的监听器回调方法添加另一个参数呢？像这样:

BaseSwipeListViewListener myBaseSwipeListViewListener = new BaseSwipeListViewListener(){
    @Override
    public void onOpened(int position, boolean toRight, SwipeListView swipeListView) {
        //Here you now have your calling swipelistview
    } 
}

在您的 BaseSwipeListViewListener 中，现在只需通过返回自身(this)来添加第三个参数。

更新:我不知道它是一个图书馆。这不是我会做的，但如果您不想编辑源代码，只需执行以下操作:

BaseSwipeListViewListener myBaseSwipeListViewListener0 = new BaseSwipeListViewListener() {
    @Override
    public void onOpened(int position, boolean toRight) {
        onOpenedAdvanced(position, toRight, swipelistview0);
    } 
}

BaseSwipeListViewListener myBaseSwipeListViewListener1 = new BaseSwipeListViewListener() {
    @Override
    public void onOpened(int position, boolean toRight) {
        onOpenedAdvanced(position, toRight, swipelistview1);
    } 
}

BaseSwipeListViewListener myBaseSwipeListViewListener2 = new BaseSwipeListViewListener() {
    @Override
    public void onOpened(int position, boolean toRight) {
        onOpenedAdvanced(position, toRight, swipelistview0);
    } 
}

public void onOpenedAdvanced(int position, boolean toRight, SwipeListView swipeListView){
    //Here you now have your calling swipelistview
}

swipelistview0.setSwipeListViewListener(myBaseSwipeListViewListener0);
swipelistview1.setSwipeListViewListener(myBaseSwipeListViewListener1);
swipelistview2.setSwipeListViewListener(myBaseSwipeListViewListener2);
