我需要一些我试图弄清楚的代码的帮助。我的项目包含用于 YouTube、Google+、Facebook 等的拉出式菜单或滑动菜单。就像那些应用程序一样，我想用手指从左向右滑动以调出菜单. 我目前拥有的是一个按钮，您必须按下该按钮才能看到我有点不想要的菜单。无论如何，这是代码：
主要活动：
public class MainActivity extends Activity
{
private ListView list;
private ArrayAdapter<String> adapter;
private RibbonMenuView rbmView;
private Button test;
private ListView rbmListView, rbmListView2;
private ArrayAdapter<String> adapt, adapter2;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/** Init our views **/
rbmView = (RibbonMenuView) findViewById(R.id.ribbonMenuView1);
list = (ListView) findViewById(R.id.listView1);
/** Calls "hideMenu()" after each click similiar to the Facebook or Google+ application **/
test = (Button) findViewById(R.id.button);
test.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
// shows how to hide the menu
if (rbmView != null)
{
rbmView.hideMenu();
}
}
});
/** This is the most important ListView, updating the main list in the Activity **/
final String[] items_list = { "Shop1", "Shop2", "Shop3" };
adapt = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items_list);
rbmListView = (ListView) findViewById(R.id.rbm_listview);
if (rbmListView != null)
{
rbmListView.setOnItemClickListener(new OnItemClickListener()
{
/*
* (non-Javadoc)
* @see android.widget.AdapterView.OnItemClickListener#onItemClick(android.widget.AdapterView, android.view.View, int, long)
*/
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
switch (position)
{
case 0:
String[] items = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items);
break;
case 1:
String[] items1 = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items1);
break;
case 2:
String[] items2 = { "Location", "Contact", "Appointment" };
adapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items2);
break;
}
// always update these
if (list != null)
{
list.setAdapter(adapter);
list.setClickable(true);
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
switch (i)
{
case 0: // Location
startActivity(new Intent(getBaseContext(), LocationActivity.class));
break;
case 1: // Contact
;startActivity(new Intent(getBaseContext(), ContactActivity.class));
break;
case 2: // Appointment
startActivity(new Intent(getBaseContext(), AppointmentActivity.class));
break;
}
}
});
}
if (rbmView != null)
{
rbmView.hideMenu();
}
}
});
rbmListView.setAdapter(adapt);
}
/** This is the second ListView on the menu **/
final String[] items_list2 = { "About", "Deals", "Contact Developer", };
adapter2 = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, items_list2);
rbmListView2 = (ListView) findViewById(R.id.rbm_listview2);
if (rbmListView2 != null)
{
rbmListView2.setOnItemClickListener(new OnItemClickListener()
{
/*
* (non-Javadoc)
* @see android.widget.AdapterView.OnItemClickListener#onItemClick(android.widget.AdapterView, android.view.View, int, long)
*/
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
switch (position)
{
case 0:
startActivity(new Intent(MainActivity.this, About.class));
break;
case 1:
startActivity(new Intent(MainActivity.this, DealsCode.class));
break;
case 2:
startActivity(new Intent(MainActivity.this, ContactDev.class));
break;
}
/*Toast.makeText(MainActivity.this, items_list2[position], Toast.LENGTH_SHORT).show();
if (rbmView != null)*/
{
rbmView.hideMenu();
}
}
});
rbmListView2.setAdapter(adapter2);
}
}
/** Allows users, even API < 5, to use the back button **/
/*
* (non-Javadoc)
* @see android.app.Activity#onKeyDown(int, android.view.KeyEvent)
*/
public boolean onKeyDown(int keyCode, KeyEvent event)
{
switch (keyCode)
{
case KeyEvent.KEYCODE_BACK:
// if view is showing, close it
// all other back button clicks are handled by the phone
if (rbmView != null)
{
if (rbmView.isMenuShowing())
{
new Handler().postDelayed(new Runnable()
{
public void run()
{
rbmView.hideMenu();
}
}, 50);
}
else
{
return super.onKeyDown(keyCode, event);
}
}
break;
default:
return super.onKeyDown(keyCode, event);
}
return true;
}
/*
* (non-Javadoc)
* @see android.app.Activity#onCreateOptionsMenu(android.view.Menu)
*/
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
/*
* (non-Javadoc)
* @see android.app.Activity#onOptionsItemSelected(android.view.MenuItem)
*/
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.test:
// toggle our menu
if (rbmView != null)
{
rbmView.toggleMenu();
}
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
}
拉出式菜单/滑动式菜单：
public class RibbonMenuView extends LinearLayout
{
private LinearLayout menu;
/**
* Constructor to create menu
* @param context Context
* @param attrs Other Attributes
*/
public RibbonMenuView(Context context, AttributeSet attrs)
{
super(context, attrs);
LayoutInflater.from(context).inflate(R.layout.rbm_menu, this, true);
menu = (LinearLayout) findViewById(R.id.menu);
}
/**
* Show our Menu
*/
public void showMenu()
{
if (menu != null)
{
new Handler().postDelayed(new Runnable()
{
public void run()
{
menu.setVisibility(View.VISIBLE);
menu.startAnimation(AnimationUtils.loadAnimation(getContext(), R.anim.rbm_in_from_left));
}
}, 50);
}
}
/**
* Hide our Menu
*/
public void hideMenu()
{
if (menu != null)
{
new Handler().postDelayed(new Runnable()
{
public void run()
{
menu.setVisibility(View.GONE);
menu.startAnimation(AnimationUtils.loadAnimation(getContext(), R.anim.rbm_out_to_left));
}
}, 50);
}
}
/**
* Toggle the Menu open/close
*/
public void toggleMenu()
{
if (menu != null)
{
if (menu.getVisibility() == View.GONE)
{
showMenu();
}
else
{
hideMenu();
}
}
}
/**
* Check to see if the menu is visible
* @return Visible
*/
public boolean isMenuShowing()
{
if (menu != null)
{
return menu.getVisibility() == View.VISIBLE;
}
return false;
}
}
告诉我是否还需要什么！
