BaseAdapter

1.创建跟Android无关的Domain

Java代码

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;

}

Java代码

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;

}

Java代码

// 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)

Java代码

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;

}

Java代码

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;

}

Java代码

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

Java代码

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;

}
