Android中如何为ListView设置静态数据

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

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;
    }
}

效果如下：
