Android 实现底部菜单栏

		menu.setNumColumns(5);// 设置每行列数
		menu.setGravity(Gravity.CENTER);// 位置居中
		menu.setVerticalSpacing(10);// 垂直间隔
		menu.setHorizontalSpacing(10);// 水平间隔
		menu.setAdapter(getMenuAdapter(a));
		menu.setOnItemClickListener(new OnItemClickListener() {

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

				case 4:
				
					break;
				}
			}
