如何在Android应用程序抽屉中添加按钮,开关,搜索栏等? 我知道如何将文本添加到列表视图中,但我发现上述内容非常困难。我下面有我当前的app抽屉。你会建议做些什么改变来实现上述目标。
代码:
MainActivity
public class MainActivity extends Activity {
// Within which the entire activity is enclosed
DrawerLayout mDrawerLayout;
// ListView represents Navigation Drawer
ListView mDrawerList;
// ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar
ActionBarDrawerToggle mDrawerToggle;
// Title of the action bar
String mTitle="";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTitle = (String) getTitle();
// Getting reference to the DrawerLayout
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.drawer_list);
// Getting reference to the ActionBarDrawerToggle
mDrawerToggle = new ActionBarDrawerToggle( this,
mDrawerLayout,
R.drawable.ic_drawer,
R.string.drawer_open,
R.string.drawer_close){
/** Called when drawer is closed */
public void onDrawerClosed(View view) {
getActionBar().setTitle(mTitle);
invalidateOptionsMenu();
}
/** Called when a drawer is opened */
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle("Select a river");
invalidateOptionsMenu();
}
};
// Setting DrawerToggle on DrawerLayout
mDrawerLayout.setDrawerListener(mDrawerToggle);
// Creating an ArrayAdapter to add items to the listview mDrawerList
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
getBaseContext(),
R.layout.drawer_list_item ,
getResources().getStringArray(R.array.rivers)
);
// Setting the adapter on mDrawerList
mDrawerList.setAdapter(adapter);
// Enabling Home button
getActionBar().setHomeButtonEnabled(true);
// Enabling Up navigation
getActionBar().setDisplayHomeAsUpEnabled(true);
// Setting item click listener for the listview mDrawerList
mDrawerList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent,
View view,
int position,
long id) {
// Getting an array of rivers
String[] rivers = getResources().getStringArray(R.array.rivers);
//Currently selected river
mTitle = rivers[position];
// Creating a fragment object
RiverFragment rFragment = new RiverFragment();
// Creating a Bundle object
Bundle data = new Bundle();
// Setting the index of the currently selected item of mDrawerList
data.putInt("position", position);
// Setting the position to the fragment
rFragment.setArguments(data);
// Getting reference to the FragmentManager
FragmentManager fragmentManager = getFragmentManager();
// Creating a fragment transaction
FragmentTransaction ft = fragmentManager.beginTransaction();
// Adding a fragment to the fragment transaction
ft.replace(R.id.content_frame, rFragment);
// Committing the transaction
ft.commit();
// Closing the drawer
mDrawerLayout.closeDrawer(mDrawerList);
}
});
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
/** Handling the touch event of app icon */
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
/** Called whenever we call invalidateOptionsMenu() */
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
// If the drawer is open, hide action items related to the content view
boolean drawerOpen = mDrawerLayout.isDrawerOpen(mDrawerList);
menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
return super.onPrepareOptionsMenu(menu);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

您可以将此库用于抽屉library
或者如果你想要这个抽屉然后放一个linearlayout然后把你的视图放在那里。
SlidingMenu menu = new SlidingMenu(this);
menu.setMode(SlidingMenu.LEFT);
menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
menu.setShadowWidthRes(R.dimen.shadow_width);
menu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
menu.setFadeDegree(0.35f);
menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
menu.setMenu(R.layout.side_panel);
现在在侧面板布局中将您的视图放在一边,现在视图侧面板使用此:
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
int itemId = item.getItemId();
switch (itemId) {
case android.R.id.home:
if (menu != null) {
menu.toggle();
}
break;
}
return true;
}
用于初始化侧面板数据使用:
menu.findViewById(R.id.your_view_id).setOnClickListener(this);
并覆盖你想要的onclick事件和句柄。
