问题描述
我正在尝试实现以下方案.
I am trying to achieve the following scenario.
一个活动，其中包含一个具有导航抽屉(从左向右滑动时打开)和一个从右向左滑动时打开的搜索栏的视图寻呼机.
An activity containing a view pager having a navigation drawer(opens when swiped left to right) and a search bar that opens when swiped right to left.
BaseActivity

public class BaseActivity extends FragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
/**

private static final int NUM_PAGES = 2;
/**

* and next wizard steps.
*/
private ViewPager mPager;
/**

*/
private PagerAdapter mPagerAdapter;
@Override

mDrawerList = (ListView) findViewById(R.id.left_drawer);
// opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
// set up the drawer's list view with items and pclick listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// if (savedInstanceState == null) {

}
//The click listener for ListView in the navigation drawer

long id) {
selectItem(position);
}
}
private void selectItem(int position) {
mDrawerList.setItemChecked(position, true);
setTitle(mPlanetTitles[position]);
Toast.makeText(this, "Title is="+getTitle(), 1).show();
mDrawerLayout.closeDrawer(mDrawerList);
}
@Override
public void onBackPressed() {
if (mPager.getCurrentItem() == 0) {
// If the user is currently looking at the first step, allow the system to handle the
// Back button. This calls finish() on this activity and pops the back stack.
super.onBackPressed();
} else {
// Otherwise, select the previous step.
mPager.setCurrentItem(mPager.getCurrentItem() - 1);
}
}
/**
* A simple pager adapter that represents 5 ScreenSlidePageFragment objects, in
* sequence.
*/
private class ScreenSlidePagerAdapter extends FragmentPagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new DashboardFragment();
case 1:

default:
return new DashboardFragment();
}
}
@Override

return NUM_PAGES;
}
}
}

能否通过使用以下布局进行尝试:

<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
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffe6e1d4"
android:focusable="true"
android:focusableInTouchMode="true" />
<ListView
android:id="@+id/left_drawer"
