android将recyclerview项位置传递给对话框按钮侦听器

单击recyclerview项中的按钮时，将显示具有多个按钮（cancalButton、deleteButton）的对话框

所以我做了两个监听器（cancelListener，deleteListener）

Show dialog成功，cancelListener运行良好，但我无法在DeltelListener中执行我想要的操作

我想在用户单击对话框中的删除按钮时删除firebase中的数据

因此，我必须知道单击recyclerview项查找数据的位置。（因为我可以通过从array.get（position.getTimestamp）获取key来查找数据

如何获取deleteListener中的项目位置

因为您的方法

private void openDialog（final int position）

具有位置信息。您可以这样做，只需为deleteListener（DeleteListenerWithItemPos）创建一个类，然后将

位置作为参数传递给构造函数

如何实现的示例如下所示：

private void openDialog(final int position){
    deleteListener = new DeleteListenerWithItemPos(position);
    dialog = new DialogDeletePin(context,cancelListener, deleteListener);
    dialog.setCancelable(true);
    dialog.getWindow().setGravity(Gravity.CENTER);
    dialog.show();
}

View.OnClickListener deleteListener;

public static class DeleteListenerWithItemPos implements View.OnClickListener() {

    private int itemPos;

    public DeleteListenerWithItemPos(int itemPos){
        this.itemPos = itemPos;
    }

    public void onClick(View v) {=
        itemPos; //get itemPos here
        Log.d("####dialog","click delete");
        dialog.dismiss();
    }
}


尚未查看整个代码，但private中的参数是否无效openDialog（最终int位置）有物品位置吗？@lyncs你好lyncs。是的，我添加了这个。但是我不知道如何才能将它传递给Deltelistener。你能显示你的代码吗DialogDeletePin@lyncx现在我添加DialogDeltePin代码！我解决了它谢谢！谢谢你的回答！我将它应用到我的代码并显示错误..在同一个java文件中添加此代码正确吗？我解决了它！谢谢不客气！你能帮我把这个标记为接受答案吗？谢谢！
private void openDialog(final int position){
    deleteListener = new DeleteListenerWithItemPos(position);
    dialog = new DialogDeletePin(context,cancelListener, deleteListener);
    dialog.setCancelable(true);
    dialog.getWindow().setGravity(Gravity.CENTER);
    dialog.show();
}

View.OnClickListener deleteListener;

public static class DeleteListenerWithItemPos implements View.OnClickListener() {

    private int itemPos;

    public DeleteListenerWithItemPos(int itemPos){
        this.itemPos = itemPos;
    }

    public void onClick(View v) {=
        itemPos; //get itemPos here
        Log.d("####dialog","click delete");
        dialog.dismiss();
    }
}
