ActivityGroup实现iPhone风格的底部tab菜单

 

java代码

public class ActsGroup extends ActivityGroup {

	private LinearLayout bodyView;
	private LinearLayout home, gamebox, team, more;
	private int flag = 0; // 通过标记跳转不同的页面，显示不同的菜单项
//	private String parameter = Constant.BUTTON_HOME;// 初始化加载

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		requestWindowFeature(Window.FEATURE_NO_TITLE); //无标题
		super.onCreate(savedInstanceState);
		setContentView(R.layout.acts_group);
		initMainView();
		// 主界面开始接收参数
		Bundle bundle = getIntent().getExtras();
		if (null != bundle) {
			flag = bundle.getInt("flag");
		}
		// 默认显示 
		showView(flag);

		home.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {
				// TODO Auto-generated method stub
				flag = 0;
				showView(flag);
			
			}
		});
		gamebox.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {
				// TODO Auto-generated method stub
				flag = 1;
				showView(flag);

			}
		});
		team.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {
				// TODO Auto-generated method stub
				flag = 2;
				showView(flag);
			
			}
		});
		more.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {
				// TODO Auto-generated method stub
				flag = 3;
				showView(flag);
				

			}
		});

	}
