   Android的菜单既可以用代码添加可以用xml文件构造，下面给大家介绍分别介绍下
一、用Xml文件构造
     Java代码：
/构建函数
public boolean onCreateOptionsMenu(Menu menu) {
// Hold on to this
mMenu = menu;
// Inflate the currently selected menu XML resource.
MenuInflater inflater = getMenuInflater();
inflater.inflate(sMenuExampleResources[mSpinner.getSelectedItemPosition()], menu);
}
//回调函数

public boolean onOptionsItemSelected(MenuItem item) {

switch (item.getItemId()) {
// For "Title only": Examples of matching an ID with one assigned in
// the XML
case R.id.jump:
Toast.makeText(this, "Jump up in the air!", Toast.LENGTH_SHORT).show();
return true;
 
case R.id.dive:
Toast.makeText(this, "Dive into the water!", Toast.LENGTH_SHORT).show();
return true;
nu);
}
