Android中ListView设置静态数据的方法

有的时候我们需要为一个listview设置固定的数据，下边就是如何设置静态的数据，之前先给大家看一看效果图：

布局文件listview 的主页面

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" >

  <listview
    android:id="@+id/listview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >
  </listview>

</linearlayout>

然后的一个布局文件为每一个listview的item，listview_item.xml有图片和文字

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="horizontal" >

  <imageview
    android:id="@+id/listitem_iv"
    android:layout_width="74dp"
    android:layout_height="74dp"
    android:src="@drawable/about_brand" />

  <textview
    android:id="@+id/listitem_tv"
    android:layout_width="match_parent"
    android:layout_height="74dp"
    android:text="textview"
    android:textalignment="center"
    android:textsize="55dp" />

</linearlayout>

然后关键的是如何设置静态数据：
这界面的控制类listviewuseadapter.java

import java.util.arraylist;
import java.util.hashmap;
import java.util.list;
import java.util.map;

import android.app.activity;
import android.os.bundle;
import android.view.view;
import android.widget.adapterview;
import android.widget.toast;
import android.widget.adapterview.onitemclicklistener;
import android.widget.listview;

public class listviewuseadapter extends activity {

  private listview listview;

  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.listview_test);

    listview = (listview) this.findviewbyid(r.id.listview);

    // 设置适配器的图片资源
    int[] imageid = new int[] { r.drawable.chat_tool_camera,
        r.drawable.chat_tool_location, r.drawable.chat_tool_paint,
        r.drawable.chat_tool_video, r.drawable.chat_tool_voice,
        r.drawable.about_brand };

    // 设置标题
    string[] title = new string[] { "相机", "定位", "画笔", "视频", "声音", "聊天" };
    list<map<string, object>> listitem = new arraylist<map<string, object>>();

    // 将上述资源转化为list集合
    for (int i = 0; i < title.length; i++) {
      map<string, object> map = new hashmap<string, object>();
      map.put("image", imageid[i]);
      map.put("title", title[i]);

      listitem.add(map);
    }

    listviewadapter adapter = new listviewadapter(this, listitem);
    listview.setadapter(adapter);
    listview.setonitemclicklistener(new onitemclicklistener() {

      @override
      public void onitemclick(adapterview<?> parent, view view,
          int position, long id) {
        toast.maketext(listviewuseadapter.this, "haha", toast.length_short).show(); 
      }
    });
  }
}

然后需要的适配器如下：

import java.util.list;
import java.util.map;
import android.content.context;
import android.view.layoutinflater;
import android.view.view;
import android.view.viewgroup;
import android.widget.baseadapter;
import android.widget.imageview;
import android.widget.textview;

public class listviewadapter extends baseadapter {

  private context context;
  private list<map<string, object>> listitem;

  public listviewadapter(context context, list<map<string, object>> listitem) {
    this.context = context;
    this.listitem = listitem;
  }

  @override
  public int getcount() {
    return listitem.size();
  }

  @override
  public object getitem(int position) {
    return listitem.get(position);
  }

  @override
  public long getitemid(int position) {
    return position;
  }

  @override
  public view getview(int position, view convertview, viewgroup parent) {
    if (convertview == null) {
      convertview = layoutinflater.from(context).inflate(r.layout.listview_item, null);
    }

    imageview imageview = (imageview) convertview.findviewbyid(r.id.listitem_iv);
    textview textview = (textview) convertview.findviewbyid(r.id.listitem_tv);

    map<string, object> map = listitem.get(position);
    imageview.setimageresource((integer) map.get("image"));
    textview.settext(map.get("title") + "");
    return convertview;
  }
}
