我将一个活动扩展为Fragment并实现了TabListner。我可以在该活动中实现TabHost（而不是Fragment TabHost）。因为当我尝试时，我找不到findViewById中的tabhost。
UserProfile.java
public class UserProfile extends Fragment implements TabListener{
private static final int RESULT_OK = -1;
private static int RESULT_LOAD_IMAGE = 1;
Map<String, AttributeValue> map = new HashMap<String, AttributeValue>();
TabHost mTabHost;
ImageView profilepic;
String userId = new PassValues().getUserId();
ArrayList<UserDetailsBean> ar = new ArrayList<UserDetailsBean>();
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_user_profile,
container, false);
TextView name = (TextView) rootView.findViewById(R.id.name);
//profilepic = (ImageView) rootView.findViewById(R.id.profile_pic);
/*mTabHost = (FragmentTabHost)rootView.findViewById(R.id.tabhost);
mTabHost.setup(getActivity(), getActivity().getSupportFragmentManager(), R.id.tabcontent1);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Tab1"),
UserDetailsActivity.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Tab2"),
UserJoinedGroupsActivity.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Tab3"),
UserPostedDiscussionActivity.class, null);*/
AsyncTask<String, String, ArrayList<UserDetailsBean>> async = new GetUserDetailsDataSource()
.execute(userId);
try {
ar = async.get();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (int i = 0; i < ar.size(); i++)
name.setText(ar.get(i).getFirstname() + " "
+ ar.get(i).getLastname());
profilepic.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
return rootView;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
System.out.println(selectedImage);
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getActivity().getContentResolver().query(
selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
System.out
.println((new PassValues().getUserId() + new LoginSharePreferences()
.getEmailId(getActivity())));
System.out.println(ar.get(0).getProfilePicPath());
AsyncTask<String, Void, Map<String, AttributeValue>> async = new InterestGroupsListDataSource(
userId, picturePath,
new LoginSharePreferences().getEmailId(getActivity()), ar
.get(0).getProfilePicPath(), "profile").execute();
try {
map = async.get();
System.out.println(map.get("Profile Image Path").getS());
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// profilepic.setImageBitmap(BitmapFactory.decodeFile(map.get("Profile Image Path").getS()));
profilepic.setImageBitmap(BitmapFactory.decodeFile(ar.get(0)
.getProfilePicPath()));
}
}
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction ft) {
// TODO Auto-generated method stub
}

您可以将活动扩展为TabActivity以在程序中获取tabhost方法。如果您的活动扩展为FragmentActivity，您可以实现任何侦听器类，但您可以在该活动中获取Tabhost。
只需将您的活动更改为
Public class *youactivity* extends TabActivity implements TabListener{
*Your code*
}
<TabHost
android:id="@+id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</TabHost>
