BaseAdapter

1.创建跟Android无关的Domain

package com.jiangqq.csdn;
public class Person {
	private String personName;
	private String personAddress;
	public Person(String personName, String personAddress) {
		super();
		this.personName = personName;
		this.personAddress = personAddress;
	}
	public String getPersonName() {
		return personName;
	}
	public void setPersonName(String personName) {
		this.personName = personName;
	}
	public String getPersonAddress() {
		return personAddress;
	}
	public void setPersonAddress(String personAddress) {
		this.personAddress = personAddress;
	}

}

package com.jiangqq.csdn;

import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

/**
 * 自定义适配器类
 * @author jiangqq  <a href=http://blog.csdn.net/jiangqq781931404></a>
 *
 */
public class MyAdapter extends BaseAdapter {
	private List<Person> mList;
	private Context mContext;

	public MyAdapter(Context pContext, List<Person> pList) {
		this.mContext = pContext;
		this.mList = pList;
	}

	@Override
	public int getCount() {
		return mList.size();
	}

	@Override
	public Object getItem(int position) {
		return mList.get(position);
	}

	@Override
	public long getItemId(int position) {
		return position;
	}
    /**
     * 下面是重要代码
     */
	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		LayoutInflater _LayoutInflater=LayoutInflater.from(mContext);
		convertView=_LayoutInflater.inflate(R.layout.item, null);
		if(convertView!=null)
		{
			TextView _TextView1=(TextView)convertView.findViewById(R.id.textView1);
			TextView _TextView2=(TextView)convertView.findViewById(R.id.textView2);
			_TextView1.setText(mList.get(position).getPersonName());
			_TextView2.setText(mList.get(position).getPersonAddress());
		}
		return convertView;
	}
}

                   // 初始化控件
			mSpinner = (Spinner) findViewById(R.id.spinner1);
			// 建立数据源
		    List<Person>  persons=new ArrayList<Person>();
			persons.add(new Person("张三", "上海 "));
			persons.add(new Person("李四", "上海 "));
			persons.add(new Person("王五", "北京" ));
			persons.add(new Person("赵六", "广州 "));
			//  建立Adapter绑定数据源
			MyAdapter _MyAdapter=new MyAdapter(this, persons);
			//绑定Adapter
			mSpinner.setAdapter(_MyAdapter);

2.创建Android有关的Domain(使用Tag方式)

package com.pandy.db.adapter;

import android.widget.ImageView;
import android.widget.TextView;

/**
 * Created with IntelliJ IDEA.
 * User: pandy
 * Date: 13-6-26
 * Time: 下午3:48
 * To change this template use File | Settings | File Templates.
 */
public class SettingListDomain {
    private ImageView sfls_imageView;
    private TextView sfls_title;
    private TextView sfls_desc;

    public TextView getSfls_title() {
        return sfls_title;
    }

    public TextView getSfls_desc() {
        return sfls_desc;
    }

    public ImageView getSfls_imageView() {

        return sfls_imageView;
    }

    public void setSfls_imageView(ImageView sfls_imageView) {
        this.sfls_imageView = sfls_imageView;
    }

    public void setSfls_title(TextView sfls_title) {
        this.sfls_title = sfls_title;
    }

    public void setSfls_desc(TextView sfls_desc) {
        this.sfls_desc = sfls_desc;
    }
}
 

package com.pandy.db.adapter;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import com.pandy.db.R;

import java.util.List;
import java.util.Map;

/**
 * Created with IntelliJ IDEA.
 * User: pandy
 * Date: 13-6-26
 * Time: 下午3:09
 * To change this template use File | Settings | File Templates.
 */
public class SettingListAdapter extends BaseAdapter {
    private Activity activity;
    private List<Map<String, Object>> data;
    private LayoutInflater layoutInflater;

    public SettingListAdapter(Activity activity, List<Map<String, Object>> data) {
        this.activity = activity;
        this.data = data;
        this.layoutInflater = LayoutInflater.from(this.activity);

    }

    @Override
    public int getCount() {
        return data.size();  //To change body of implemented methods use File | Settings | File Templates.
    }

    @Override
    public Object getItem(int i) {
        return data.get(i);  //To change body of implemented methods use File | Settings | File Templates.
    }

    @Override
    public long getItemId(int i) {
        return i;  //To change body of implemented methods use File | Settings | File Templates.
    }

    @Override
    public View getView(int i, View view, ViewGroup viewGroup) {

        SettingListDomain domain = null;
        if (view == null) {
            domain = new SettingListDomain();
            view = layoutInflater.inflate(R.layout.setting_fun_list_sub, null);
            domain.setSfls_imageView((ImageView) view.findViewById(R.id.sfls_imageView));
            domain.setSfls_title((TextView) view.findViewById(R.id.sfls_title));
            domain.setSfls_desc((TextView) view.findViewById(R.id.sfls_desc));
            view.setTag(domain);
        } else {
            domain = (SettingListDomain) view.getTag();
        }

//        domain.getSfls_imageView().setBackgroundColor((Integer) data.get(i).get("sfls_imageView"));
        domain.getSfls_imageView().setImageResource((Integer) data.get(i).get("sfls_imageView"));
        domain.getSfls_title().setText((String) data.get(i).get("sfls_title"));
        domain.getSfls_desc().setText((String) data.get(i).get("sfls_desc"));
        return view;
    }
}

        sfl_listView = (ListView) findViewById(R.id.sfl_listView);
        SettingListAdapter adapter = new SettingListAdapter(this, SystemDataUtils.getSettingFunListData(SettingFunListActivity.this));
        try {
            sfl_listView.setAdapter(adapter);
            sfl_listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                    Map<String, Object> map = (Map<String, Object>) adapterView.getAdapter().getItem(i);
                    doSetting(map.get("sfls_title").toString());
                }
            });
        } catch (Exception e) {
            ToastUtils.show(this, e);
        }

3.直接使用

package com.gv;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;

public class ImageAdapder extends BaseAdapter {
	private Context context;
	private int[] images;

	public ImageAdapder(Context context,int[] images){
		this.context = context;
		this.images = images;
	}
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return images.length;
	}

	@Override
	public Object getItem(int position) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return 0;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ImageView imageView = new ImageView(context);
		imageView.setImageResource(images[position]);
		return imageView;
	}

}
