动态更改listview的分频高度？ [英] change the divider height of listview dynamically?

问题描述

此问题已在此被问到链接

此外，我想澄清问题
我在Listview中有10个列表项
我想让每个列表项的deviderheight有所不同喜欢第一个项目应该是setDividerheight（2）for 2nd setDividerheight（4）like this ..

我已经制作了一个自定义的Adapeter，其中我设置了我的布局

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

但这似乎无法正常工作。

以上任何想法，如何动态设置Listview的分隔线高度

解决方案

  //设置分隔符，你喜欢
 
 listView.setDivider （（Drawable）getResources（）。getDrawable（R.drawable.orange））; 
 
 //然后动态设置高度
 
 listView.setDividerHeight（1）; 
  

在您的Activity中有ListView。不是适配器类。

如果你在问题中写的是什么。这样做：

让每个listView项目布局包含一个TextView和一个View（每个项目之后的分隔符），然后根据getView（）方法中得到的position参数更改视图的高度。

ListView项目布局：

  <？xml version =1.0encoding =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> 
  

现在在适配器类中，ViewHolder包含TextView和View。

所以

  Holder.View =（查看）convertView.findViewById（R.id。视图）; 
 if（position == 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.
