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.classpublic 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); }}
