Swipeable views in for each individual navigation drawer item

My app has a navigation drawer with a few items and have 2 swipeable views. My question is, how can I make those swipeable views have different title and content depending on what navigation drawer item I click on. Currently I click on any navigation drawer item it displays the same swipeable views.
Please let me know if you need some clarification or something. Thanks!
Edit: Just so I'm clear. I don't mean swipeable views inside the nav drawer. When I tap on the nav drawer item, it takes me to that layout.

Follow this link. It has your exact requirements. The following functions should be useful for you. Try it out. It handles navigation drawer, and navigation drawer item clicks.
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
selectItem(position);
}
}
and

FragmentTransaction ft = fragmentManager.beginTransaction();
switch (position) {
case 0:
ft.replace(R.id.content_frame, new Fragment1, Constants.TAG_FRAGMENT).commit();

Android Navigation draw not displaying images and text

I am trying to create a navigation draw which displays text and images. My project builds OK but when I open the navigation draw there is no text or images displayed. I have created a layout file for the image and text to be displayed on the navigation draw and I have set the adapter for the navigation draw as well as creating my own Adapter class.
I cant see what is wrong but something obviously is :) Any help is greatly appreciated.
Here are my files

Android Navigation Drawer Content Frame Cannot be resolved

I am using the following code to implement a simple navigation drawer based on the sample given in the Android Developers site.

public static class PlanetFragment extends Fragment {

getActivity().setTitle(planet);
return rootView;
}
}
}
But I get an error saying "content_frame cannot be resolved". How do I fix this ?

Change the id of the frame... its normally container... But change it to content_frame and you are good.

ActionbarSherlock Navigation Drawer

I am trying to change the TextViews in ActionBarSherlock Navigation drawer to EditTexts with hints.
so far i have accomplished to create edit texts from it (which was piece a cake) but i cannot seem to find out how to create a Hint from the text, it appears as filled in editTexts now..
how can i change it?
Below is my code.
As i do not know which part is relevant, i post a lot of code.
mFragmentTitles = getResources().getStringArray(R.array.nav_drawer_items);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
mDrawerList = (ListView)findViewById(R.id.drawer_list);

In my Xml is an EditText (drawer_list_item.xml)
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:gravity="center_vertical"
android:textColor="#fff"
android:minHeight="48dp"/>
and this is my other XML which i use to display the drawer.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/drawer" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame"/>
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:divider="#0c7f58"
android:dividerHeight="1dp"
android:background="#13ca8c"
android:choiceMode="singleChoice"
android:layout_gravity="end"
android:paddingLeft="16dp"
android:paddingRight="16dp"
/>
</android.support.v4.widget.DrawerLayout>

An ArrayAdapter, by default, loads the string value of each item as the corresponding TextView's text. It's implementation of getView() is:
if (convertView == null) {
view = mInflater.inflate(resource, parent, false);
} else {
view = convertView;
}
<irrelevant stuff snipped>
T item = getItem(position);
if (item instanceof CharSequence) {
text.setText((CharSequence)item);
} else {
text.setText(item.toString());
}
If what you want to do is load the hint instead of the text, you should override this method. For example, as this:
EditText edit = (EditText)LayoutInflater.from(getContext()).inflate(R.layout.drawer_list_item);
edit.setHint(getItem(position).toString());
That will get the corresponding string as hint, instead of text.

the way to fix this is to create a custom MenuAdapter and put the edit texts in there.
mMenuAdapter = new MenuListAdapter(MainFragActivity.this, title);
mDrawerList.setAdapter(mMenuAdapter);
//In your main class put the above code, then in your custom class put the below code;
import com.actionbarsherlock.app.SherlockFragment;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
public class MenuListAdapter extends BaseAdapter {
// Declare variables
Context context;
String[] mTitle;
String[] mSubTitle;
LayoutInflater inflater;
public MenuListAdapter(Context context, String[] title) {
this.context = context;
this.mTitle = title;
}
#Override
public int getCount() {
return mTitle.length;
}
#Override
public Object getItem(int position) {
return mTitle[position];
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Declare Variables
EditText txtTitle;
TextView txtSubTitle;
ImageView imgIcon;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.drawer_list_item, parent, false);
// Locate the TextViews
txtTitle = (EditText)itemView.findViewById(R.id.title);
// Set the data
txtTitle.setHint(mTitle[position]);
txtTitle.setBackground(null);
return itemView;
}
}

show a blank screen when selecting a fragment for the second time

In my application, I have used the SherlockNavigationDrawer. By default, the navigationDrawer has 3 menu to opens 3 fragments. I have modified one of the following fragment. But when click for the second time on the menu of my fragment, screen not display anything! The first time, no problem; But the second time, a blank page is displayed.
In this case, if click on the default fragment menu in NavigationDrawer and then click on my fragment on the screen comes back on, but if click on my fragment menu again, screen show a blank page!
Also i have shown in my fragment a list of items, that by click on each item replace new fragment that show details of the specific item. but detail fragment is a display that is empty!!!
Friends! Where is the problem?

I don't know if this question is still available but for someone could be a helpful answer.
That's what you should do :
change from
android.support.v4.app.FragmentPagerAdapter to android.support.v4.app.FragmentStatePagerAdapter

try to change getSupportFragmentManager to getChildFragmentManager
