按键的处理思路：
/*
* 监听菜单键,当用户点击菜单键的时候，显示和隐藏一级和二级菜单
*
* 监听返回键,再按一次退出程序
*/
private long exitTime = 0;
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// 菜单键的处理
if(event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_MENU){
// 如果 一级菜单显示,隐藏 全部
if(isShowLevel1){
MyAnimationUtils.animaOut(level);
isShowLevel1 = false;
if(isShowLevel2){
MyAnimationUtils.animaOut(level2,120);
isShowLevel2 = false;
if(isShowLevel3){
MyAnimationUtils.animaOut(level3,120);
isShowLevel3 = false;
}
}
}else{
// 如果一级菜单式隐藏的,显示 一,二级菜单
MyAnimationUtils.animaIn(level);
MyAnimationUtils.animaIn(level2, 120);
isShowLevel1 = true;
isShowLevel2 = true;
}
}
// 返回键
if(event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_BACK){
if(System.currentTimeMillis() - exitTime > 2000){
Toast.makeText(this, "再按一次返回键退出", Toast.LENGTH_SHORT).show();
exitTime = System.currentTimeMillis();
}else{
finish();
System.exit(0);
}
return true;
}
return super.onKeyDown(keyCode, event);
}
