Android UI开发第五篇——自定义列表

自定义列表，设置列表背景、列表的列背景、列表的间隔线。
借鉴了一些前辈的代码。

MainActivity.class

public class MainActivity extends Activity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

//绑定Layout里面的ListView

ListView list = (ListView) findViewById(R.id.ListView01);

//生成动态数组，加入数据

ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String, Object>>();

for(int i=0;i<5;i++)

{

if(i==0){

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("ItemImage", R.drawable.checked);//图像资源的ID

map.put("ItemTitle", "个人信息");

map.put("LastImage", R.drawable.lastimage);

listItem.add(map);

}else if(i==1){

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("ItemImage", R.drawable.c);//图像资源的ID

map.put("ItemTitle", "修改密码");

map.put("LastImage", R.drawable.lastimage);

listItem.add(map);

}else if(i==2){

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("ItemImage", R.drawable.d);//图像资源的ID

map.put("ItemTitle", "网络设置");

map.put("LastImage", R.drawable.lastimage);

listItem.add(map);

}else if(i==3){

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("ItemImage", R.drawable.d);//图像资源的ID

map.put("ItemTitle", "打印设置");

map.put("LastImage", R.drawable.lastimage);

listItem.add(map);

}else{

HashMap<String, Object> map = new HashMap<String, Object>();

map.put("ItemImage", R.drawable.e);//图像资源的ID

map.put("ItemTitle", "返回");

map.put("LastImage", R.drawable.lastimage);

listItem.add(map);

}

}

//生成适配器的Item和动态数组对应的元素

SimpleAdapter listItemAdapter = new SimpleAdapter(this,listItem,// 数据源

R.layout.list_items,//ListItem的XML实现

//动态数组与ImageItem对应的子项

new String[] {"ItemImage","ItemTitle", "LastImage"},

//ImageItem的XML文件里面的一个ImageView,两个TextView ID

new int[] {R.id.ItemImage,R.id.ItemTitle,R.id.last}

);

//添加并且显示

list.setAdapter(listItemAdapter);

//添加点击

list.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,

long arg3) {

setTitle("点击第"+arg2+"个项目");

if(arg2 == 4){

MainActivity.this.finish();

}

}

});

//添加长按点击

list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

@Override

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {

menu.setHeaderTitle("长按菜单-ContextMenu");

menu.add(0, 0, 0, "弹出长按菜单0");

menu.add(0, 1, 0, "弹出长按菜单1");

}

});

}

//长按菜单响应函数

@Override

public boolean onContextItemSelected(MenuItem item) {

setTitle("点击了长按菜单里面的第"+item.getItemId()+"个项目");

return super.onContextItemSelected(item);

}

}
