菜单包括选项菜单(OptionMenu)、上下文菜单(ContextMenu)、子菜单(SubMenu).
创建子菜单(SubMenu)的步骤:

代码如下:
public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { //创建子菜单 SubMenu subMenu1=menu.addSubMenu("子菜单1"); //设置菜单头的标题 subMenu1.setHeaderTitle("菜单头的标题1"); //设置菜单的图标 subMenu1.setIcon(R.drawable.ic_launcher); //设置菜单头的图标 subMenu1.setHeaderIcon(R.drawable.ic_launcher); //向0组中添加菜单项 subMenu1.add(0, 0, 0, "菜单项1"); subMenu1.add(0, 1, 0, "菜单项2"); subMenu1.add(0, 2, 0, "菜单项3"); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // TODO Auto-generated method stub toast(item.getTitle()); return super.onOptionsItemSelected(item); } private void toast(CharSequence title) { // TODO Auto-generated method stub Toast.makeText(MainActivity.this,title, Toast.LENGTH_SHORT).show(); } }
