我是ActionBarCompat库的新手。我想开发一个包含多个片段的应用程序。这就是我想做的事情
1.当用户从导航抽屉中选择片段时，如何打开片段。
2.如何设置显示启动布局的启动片段（例如 - 在Google plus app中，首先显示新闻源。当我们从侧面菜单中选择个人资料项目时，它会隐藏侧面菜单/导航抽屉并显示配置文件布局）
目前我有侧边菜单和一个片段。 以下是我过去遵循的教程 - wptrafficanalyzer

我假设通过侧边菜单你的意思是导航抽屉。您可以在以下链接中找到答案。
Navigation Drawer with backword compatibility android
请阅读
http://developer.android.com/design/patterns/navigation-drawer.html
片段由活动托管。因此，您需要活动布局中的容器。
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout // container to which you add or replace fragments
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>
最初，您不要点击任何项目。所以最初将fragment1添加到容器中。
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
根据位置点击listitem
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();

如果您打算使用滑出式菜单，我建议您使用此slidemenu library我在我的应用程序中使用它，它允许您在幻灯片菜单中放置任何您想要的内容，菜单只是一个框架布局，你可以把任何你想要的东西（Listview，GridView，甚至只是一张图片）

您好检查此代码
公共类MainActivity扩展了ActionBarActivity实现 OnItemClickListener {
DrawerLayout options_drawer;
FrameLayout main_frame;
ListView slider_list;
ActionBar action;
ActionBarDrawerToggle toggler;
BluetoothAdapter blue_adapter;
String options[] = { "Chat", "Device List", "Settings", "Emojis",
"Terms&Conditions" };

private static final int REQUEST_ENABLE_BT = 3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// supportRequestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.activity_main);
// setSupportProgressBarIndeterminateVisibility(true);
action = getSupportActionBar();
action.setHomeButtonEnabled(true);
action.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
options_drawer = (DrawerLayout) findViewById(R.id.drawer);
main_frame = (FrameLayout) findViewById(R.id.main_frame);
slider_list = (ListView) findViewById(R.id.slider_list);
blue_adapter = BluetoothAdapter.getDefaultAdapter();
if (blue_adapter == null) {
Toast.makeText(getApplicationContext(),
"NO BLUETOOTH DEVICE FOUND", Toast.LENGTH_LONG).show();
finish();
}
ArrayAdapter<String> al = new ArrayAdapter<String>(
getApplicationContext(), R.layout.option_text, options);
slider_list.setAdapter(al);
slider_list.setOnItemClickListener(this);
/*

*/
// options_drawer.setDrawerListener(toggler);
if (savedInstanceState == null) {
f = new chat_fragment();
fragmentTransition(f);
}
}
@Override
public void onStart() {
super.onStart();
// If BT is not on, request that it be enabled.
// setupChat() will then be called during onActivityResult
if (!blue_adapter.isEnabled()) {
Intent enableIntent = new Intent(
BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableIntent, REQUEST_ENABLE_BT);
// Otherwise, setup the chat session
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
if (item.getItemId() == android.R.id.home) {
// If the drawer is open, close it; vice versa
if (options_drawer.isDrawerOpen(slider_list)) {
options_drawer.closeDrawer(slider_list);
} else {
options_drawer.openDrawer(slider_list);
}
}
return super.onOptionsItemSelected(item);
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
options_drawer.closeDrawer(slider_list);
switch (position) {
case 0:
f = new chat_fragment();
fragmentTransition(f);
break;
case 1:
f = new device_list_fragment();
fragmentTransition(f);
break;
}
}
private void fragmentTransition(Fragment f2) {
// TODO Auto-generated method stub
FragmentTransaction fx = getSupportFragmentManager().beginTransaction();
fx.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
fx.replace(R.id.main_frame, f2).commit();
}
}
