Android 中添加menu菜单

menu样式

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android" >    <item        android:id="@+id/menu_prefs"        android:title="设置"/>    <item        android:id="@+id/menu_quit"        android:title="退出"/></menu>

在activity中复写下面两个方法

@Override    public boolean onCreateOptionsMenu(Menu menu) {        MenuInflater inflater = getMenuInflater();        inflater.inflate(R.menu.mainmenu, menu);        return true;    }    @Override    public boolean onOptionsItemSelected(MenuItem item) {        if (item.getItemId() == R.id.menu_prefs) {            Intent intent = new Intent(this, ShareToOtherTest.class);            startActivityForResult(intent, 0);        } else if (item.getItemId() == R.id.menu_quit) {            finish();        }        return true;    }
