一个可以掌握所有Android控件的Demo,欢迎广大朋友下载使用!我从中受益不浅,所以特拿来与天底下对正在学习Android的朋友们一起分享,里面有一个压缩包,解压后有五个工程文件,通过Import导入到eclipse里去,然后找你们想学的控件开始学习吧!
示例代码:
package com.cellcom;
import Android.app.Activity;
import Android.os.Bundle;
import Android.view.Menu;
import Android.view.MenuItem;
import Android.view.SubMenu;
//子菜单subMenu
public class SubMenuActivity extends Activity {
private final static int ITEM_NEW_FILE=Menu.FIRST;
private final static int ITEM_OPEN_FILE=Menu.FIRST+1;
private final static int ITEM_COPY=Menu.FIRST+2;
private final static int ITEM_CLOSE=Menu.FIRST+3;
private final static int ITEM_SAVE=Menu.FIRST+4;
private final static int ITEM_SAVE_ALL=Menu.FIRST+5;
private final static int ITEM_CUT=Menu.FIRST+6;
private final static int ITEM_PASTE=Menu.FIRST+7;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.sub_menu);
setTitle("单击Menu键看到效果!");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
SubMenu file=menu.addSubMenu("文件");
SubMenu edit=menu.addSubMenu("编辑");
file.add(0,ITEM_NEW_FILE,0,"新建");
file.add(0,ITEM_OPEN_FILE,0,"打开");
file.add(0,ITEM_CLOSE,0,"关闭");
file.add(0,ITEM_SAVE,0,"保存");
file.add(0,ITEM_SAVE_ALL,0,"保存全部");
edit.add(0,ITEM_COPY,0,"复制");
edit.add(0,ITEM_CUT,0,"剪切");
edit.add(0,ITEM_PASTE,0,"粘贴");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case ITEM_NEW_FILE:
setTitle("新建文件!");
break;
case ITEM_OPEN_FILE:
setTitle("打开文件");
break;
case ITEM_COPY:
setTitle("复制文件");
break;
default:
break;
}
return true;
}
}
