与部分重叠的自定义视图中的项目列表视图（安卓） [英] List view with custom view items with partially overlaps (Android)

问题描述

我想实现一个列表在Android中包含一些自定义的视图。 我的问题是我想要的意见将被放在一个接一个，而它们之间几乎没有重叠。就像下面的模式：

I want to implement a list in Android that contains some customized views. My problem is that I want the the views will be put one after the other with a little overlap between them. like in the following schema:

我也希望控制这种重叠以这样的方式，当用户点击的项目之一，他们将移动分开彼此

I also want to control this overlap in such a way that when the user clicks on one of the items, they will move apart from each other.

我试图扩大ListView的，但它似乎很模糊，有什么建​​议？

I tried to extend ListView but it seems to be very obscured, any suggestions?

编辑： 这样可以更清楚的：

This can be more clear:

我通过设置分隔高度-50dp做到了。 这正是我想要实现，但不知何故，不能在我的应用程序的体现。

I did it by setting the divider height to -50dp. this is exactly what I want to achieve, but somehow it doesn't reflect on my app.

推荐答案

我设法用滚动视图用一个相对布局作为一个孩子来实现这一点。 我再动态地将意见通过定义规则，保证金：

I managed to achieve this by using scroll view with a single relative layout as a child. I then dynamically place the views by defining a rule and margin:

for (int i = 0; i < 30; i++) {
        TextView tv = new TextView(context);
        tv.setText("Text \n Text" + i);

        tv.setBackgroundColor(i % 2 == 0 ? Color.RED : Color.GREEN);

        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
        lp.addRule(RelativeLayout.ALIGN_PARENT_TOP);
        lp.leftMargin = 0;
        lp.topMargin = (i * 45);
        rl.addView(tv, lp);
}

之后，你可以通过改变他们的Y值控制的子视图的位置（例如：如果你想添加动画）

Later, you can control the positioning of the sub-views by changing their y value (for example: if you want to add animation).

这是最后的结果是：
