我创建了一个示例应用程序来测试滑动菜单的工作原理屏幕截图中显示的是我现在所获得的内容.但是当我点击“类别”按钮(如下图所示)时,我应该得到一个二级菜单,如下面的zomato app截图所示.我怎样才能做到这一点 ？我是以正确的方式进行的吗？
我的SlidingFragmentActivity：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
con = this;
setSlidingActionBarEnabled(false);
setContentView(R.layout.main);
sm = getSlidingMenu();
sm.setMode(SlidingMenu.RIGHT);
sm.setShadowDrawable(R.drawable.shadowright);
sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_NONE);
sm.setBehindScrollScale(1.0f);
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
sm.setFadeDegree(0.5f);
//sm.setSecondaryMenu(R.layout.properties);
//sm.setSecondaryShadowDrawable(R.drawable.shadow);
setTitle("Sliding Bar");
// set the Behind View
setBehindContentView(R.layout.menu_frame);
FragmentTransaction t = this.getSupportFragmentManager()
.beginTransaction();
mFrag = new SampleListFragment();
t.replace(R.id.menu_frame,mFrag);
t.commit();
}
我的SampleListFragment：
public class SampleListFragment extends SherlockFragment {
private static final String[] Radio_buttons = new String[] { "Distance","Rating" };
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.list,container,false);
ListView radio_list = (ListView) view.findViewById(R.id.RadioList);
Button categories = (Button) view.findViewById(R.id.sampleButton);
radio_list
.setAdapter(new ArrayAdapter<String>(MainActivity.con,android.R.layout.simple_list_item_single_choice,Radio_buttons));
radio_list.setItemsCanFocus(true);
radio_list.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
categories.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
MainActivity.sm.showSecondaryMenu();
}
});
return view;
}
}
main.xml中

解决方法
SlidingMenu不会这样做,zomato使用自定义实现.
SlidingMenu会让你左边和右边都有一个菜单,但两边都不是两个.
我会看一下使用视图寻呼机或自定义实现.无论如何,我不知道开箱即用的任何事情.我可能值得看一下Android Views的灵感.
