Android仿抖音评论列表(加评论功能)/网易云音乐列表

老规矩 先上效果图

附下Demo TikTok

如果想要实现抖音一样的评论功能,就要再列表dialog上面再弹出一个dialog.

那么问题来了:当评论的dialog弹出来的时候两个dialog就会被顶起,但是我们想要的是评论列表不要被顶起
给评论列表的dialog设置此方法即可

 Window win = dialog.getWindow();
        WindowManager.LayoutParams params = win.getAttributes();
        win.setSoftInputMode(params.SOFT_INPUT_ADJUST_NOTHING);

添加依赖 版本根据你build版本来
