安卓集列表视图高度动态 [英] android set listview height dynamically

问题描述

我有 ExpandableListview 在滚动型，我知道那不是很好，但我有太多，展现唯一的解决办法整个名单是由code。使用设置其高度的LayoutParams

i have ExpandableListview inside ScrollView and i know that's not good but i had too, the only solution to show the whole list is by set its height by code using layoutParams

RelativeLayout.LayoutParams PARAMS =新
  RelativeLayout.LayoutParams（LayoutParams.MATCH_PARENT，
  ListViewData.length（））;

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, ListViewData.length());

这个解决方案是好的，但我不认为我应该给出正确的高度 PARAMS ，那么，有没有办法知道从尺寸实际尺寸阵列的

this solution is good but i can't figure the right height that i should give in the Params, SO is there a way to know the actual size from the size of the array

编辑：
我想出了，每次我展开一个组列表时的解决方案会改变高度，以适应新的geight

i came up with a solution that everytime i expand a group of the list am gonna change the height to fit with new geight

推荐答案

您的ListView是在这种情况下，有效地不需要即可。你可以在你的适配器的项目，以及循环，只是将它们添加到一个垂直的LinearLayout的滚动型内。

Your ListView is effectively unneeded in this case. You can as well loop over your adapter's items and just add them to a vertical LinearLayout inside your ScrollView.

如果你不想改变很多code的：

In case you do not want to change a lot of code:

替换 ListView.setAdapter 与

LinearLayout ll; //this should be the vertical LinearLayout that you substituted the listview with
for(int i=0;i<adapter.getCount();i++) {
    View v = adapter.getView(position, null, null);
    ll.addView(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
}

如果您已经使用了OnItemClickListener之后添加视图V = adapter.getView（位置，NULL，NULL）; 以下

If you already use an OnItemClickListener add after View v = adapter.getView(position, null, null); the following

final int position = i;
v.setOnClickListener(new OnClickListener() {
    public onClick(View v) {
        yourOnItemClickListener.onItemClick(null, v, position, 0);
    }
});

在这种情况下，你不必担心在高度的任何错误判断。

In this case you do not have to worry about any miscalculation in the height.
