动态改变列表视图的分隔高度?视图、高度、动态、列表

2023-09-06 04:23:11 作者:几重烟水

这个问题已经在这里a链接

此外,我想澄清的问题 我有一个列表视图10列表项 我想有每个列表项的deviderheight不同像第一个项目应该setDividerheight(2)第二setDividerheight(4)这样的..

我做了一个自定义的Adapeter中,我设置我的布局如同

公开查看getView(INT位置,查看convertView,ViewGroup中父){         视图V = super.getView(位置,convertView,父母);

 如果(位置== 2)
    {
         如果(V = convertView和放大器;!&安培;!V = NULL){
             ViewHolder持有人=新ViewHolder();

            // TextView的电视=(TextView中)v.findViewById(R.id.artist_albums_textview);
            // holder.albumsView =电视;

             convertView = mInflater.inflate(R.layout.jazz_artist_list_item,NULL);
             holder.albumsView =(TextView中)convertView.findViewById(R.id.artist_albums_textview);

          // lv.setDividerHeight(8);
             v.setTag(保持器);
           }
    }
    其他
    {
         如果(V = convertView和放大器;!&安培;!V = NULL){
             ViewHolder持有人=新ViewHolder();

             convertView = mInflater.inflate(R.layout.jazz_artist_list_item,NULL);
             holder.albumsView =(TextView中)convertView.findViewById(R.id.artist_albums_textview);

           // lv.setDividerHeight(2);
             v.setTag(保持器);
           }
    }
 

但这似乎不能正常工作。

以上任何想法如何设置列表视图的分隔高度动态

问候, Laxmikant

解决方案

  //设置分频器,只要你喜欢

listView.setDivider(。(可绘制)getResources()getDrawable(R.drawable.orange));

//然后动态设置高度

listView.setDividerHeight(1);

在你的活动有ListView控件。没有适配器类。

如果你什么,你的问题写什么。做到这一点:

让每一个列表视图项布局包含一个TextView和一个视图(分隔每个项目后),则取决于你在getView(获得位置参数)方法来改变观看的高度。

ListView项的布局:

 < XML版本=1.0编码=UTF-8&GT?;
< RelativeLayout的的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
    机器人:layout_width =FILL_PARENT
    机器人:layout_height =WRAP_CONTENT
    机器人:填充=5DP>
    <的TextView
        机器人:ID =@ + /标记
        机器人:layout_width =WRAP_CONTENT
        机器人:layout_height =WRAP_CONTENT
        机器人:layout_toRightOf =@ ID /标志
        机器人:填充=5DP
        机器人:TEXTSIZE =14dp>
    < / TextView的>
    <查看
        机器人:ID =@ + ID /视图
        机器人:layout_width =FILL_PARENT
        机器人:layout_height =1DP
        机器人:layout_below =@ /标记
        机器人:背景=@可绘制/橙色/>
< / RelativeLayout的>
 

现在的适配器类的ViewHolder包含了TextView的,也是观。

所以,

  Holder.View =(查看)convertView.findViewById(R.id.view);
如果(位置== 0){
     (Holder.View).setHeight(2);
}
 

等等。

This question has been asked here a link

Also I want to clarify the question I have 10 List Items in a Listview I want to have the deviderheight of each List Items differently like for first Item it should be setDividerheight(2) for 2nd setDividerheight(4) like this..

I have made a custom Adapeter in which I am setting my Layout Like

public View getView(int position, View convertView, ViewGroup parent) { View v = super.getView(position, convertView, parent);

    if(position ==2)
    {
         if (v != convertView && v != null) {
             ViewHolder holder = new ViewHolder();

            // TextView tv = (TextView) v.findViewById(R.id.artist_albums_textview);
            // holder.albumsView = tv;

             convertView = mInflater.inflate(R.layout.jazz_artist_list_item, null);
             holder.albumsView = (TextView)convertView.findViewById(R.id.artist_albums_textview);

          //   lv.setDividerHeight(8);
             v.setTag(holder);
           }
    }
    else
    {
         if (v != convertView && v != null) {
             ViewHolder holder = new ViewHolder();

             convertView = mInflater.inflate(R.layout.jazz_artist_list_item, null);
             holder.albumsView = (TextView)convertView.findViewById(R.id.artist_albums_textview);

           //  lv.setDividerHeight(2);
             v.setTag(holder);
           }
    }

but this seems not working properly.

Any idea on above this as how to set the divider height of Listview dynamically

Regards, Laxmikant

解决方案

//set Divider as you like   

listView.setDivider((Drawable) getResources().getDrawable(R.drawable.orange));

//then set the height dynamically

listView.setDividerHeight(1);

in your Activity which has the ListView. Not the Adapter class.

If you what exactly what you wrote in the question. Do this:

let each listView Item layout contain a TextView and a View(divider after each item), then depending on the position parameter you get in the getView() method change the Height of the View.

ListView Item layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="5dp" >
    <TextView
        android:id="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/logo"
        android:padding="5dp"
        android:textSize="14dp" >
    </TextView>
    <View
        android:id="@+id/view"
        android:layout_width="fill_parent"
        android:layout_height="1dp"
        android:layout_below="@id/label"
        android:background="@drawable/orange" />
</RelativeLayout>

now in the adapter class your ViewHolder contains the TextView and also the View.

so,

Holder.View = (View)convertView.findViewById(R.id.view);
if(position == 0){
     (Holder.View).setHeight(2);
}

and so on.
