Question

I have two class both using fragment; FirstFragment class and SignUp class. Using one fragment at a time. In the FirstFragment there is a button and on clicking the button i have to go to next fragment.But when clicking on the button i got error.

Here is the code of FirstFragment classs

package com.example.bajraregistertesteclipse;

import java.util.zip.Inflater;


import android.app.Fragment;
import android.app.FragmentTransaction;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class FirstFragment extends Fragment {
LoginDataBaseAdapter loginDataBaseAdapter;
EditText loginTestUser,loginTestPassword,loginTestConfirmPassword;
String userName,password,confirmpassword;


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

      View view = inflater.inflate(R.layout.firstfragment, container, false);
       Button btnSignup = (Button) view.findViewById(R.id.buttonCreateAccount); 
       btnSignup.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                SignUp signup=new SignUp();
                 FragmentTransaction ft = getFragmentManager().beginTransaction();
                 ft.replace(R.id.listFragment, signup);
                 ft.addToBackStack(null);
                 ft.commit();


                }

        });

       return view;
}


}

Here is the code of activity_main xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:tools="http://schemas.android.com/tools"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:orientation="horizontal">

<fragment
        android:id="@+id/listFragment"
        android:layout_width="211dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:layout_marginTop="?android:attr/actionBarSize"
        class="com.example.bajraregistertesteclipse.FirstFragment"
                  tools:layout="@layout/firstfragment"/>

Thank you in advance!!!

@Rick77 application will crash....Message: Unfortunately your application has stopped. — Bhim Prasad Ale, May 27 '13 at 19:28
:D I meant "what kind of error does logcat give to you?". Logcat is the Android logging facility: it gives you a lot of useful information about the ongoing processes, allows you to easily print debugging statements (e.g. to inspect variables) and prints a traceback when things go awry: http://developer.android.com/tools/debugging/debugging-log.html — Rick77, May 27 '13 at 19:29
can you show code for SignUp signup=new SignUp(); Because your problem related to some leak: android.app.ServiceConnectionLeaked: Service com.android.exchange.ExchangeService has leaked ServiceConnection com.android.emailcommon.service.ServiceProxy$ProxyConnection@40cebd08 that was originally bound here — Borys, May 27 '13 at 20:19
StrictMode, ExchangeService, ServiceConnection - is it your classes? Because your errors somehow related to those classes. There is one black box point - loginDataBaseAdapter= loginDataBaseAdapter.open(); — Borys, May 27 '13 at 20:35
@Borys sorry for late rply....no strictmode exchange service is not a class — Bhim Prasad Ale, May 28 '13 at 05:27

Can you update Logcut with error around WindowManager$BadTokenException. Seems it's your problem. — Borys, May 28 '13 at 07:12
@Borys how can we replace the new UI fragment replacing existing UI in fragments. — Bhim Prasad Ale, May 28 '13 at 08:02
I update my answer, look here and try workaround from that links. — Borys, May 28 '13 at 10:18
@Borys thank you for the answer.it worked. now the problem is the Handling Run-Time Configuration Changes in fragments. When i rotate the screen. As i did research i came to know that i have to use like " setRetainInstance(true); but i dont know how to use it..Do you have any idea on it ??? — Bhim Prasad Ale, May 28 '13 at 11:38

I think some thing wrong with

 ft.replace(R.id.listFragment, signup);

I searsh a litle bit and find may be related topics:

So workaround is "remove the fragment from the xml and use FrameLayout component in the replace() method."

UPDATE: Read this cerfuly and implement dinamycaly add Fragment instead of static in xml. Google provide example how to add it dynamicaly.

change your xml to FrameLayout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

in onCreate() place your first fragment (you need to move it to some class)

  // Add the fragment to the 'fragment_container' FrameLayout
  getSupportFragmentManager().beginTransaction()
          .add(R.id.fragment_container, firstFragment).commit();

onClick method:

    SignUp signup=new SignUp();
    // Add the fragment to the 'fragment_container' FrameLayout
    getSupportFragmentManager().beginTransaction()
            .add(R.id.fragment_container, signup).commit();

It's in theory I don't tried it by ny self.
