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);
}
}
