Swipe Left Swipe Right textview in fragment - Android app

Please suggest me how implement Swipe left or right in my app? Is page viewer or gesture can be used. I get content for text view from string array when item clicked. I am new to app development.

I didn't understand if that actually what you trying to do but as i understood if you want the TextView moves automatically in one line to show the rest of it make this:
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:freezesText="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true" />
and in code after defining it's view make this:
textView.setChecked(true);

How to add swiping gesture on fragment TAbHost

I want to change tab by swiping on the screen i am creating tabs using fragment tabhost but when i implement swiping feature in my project it doesn't open nested fragment in each tab means i am opening nested child fragment inside each tab.
Please tell me its very important for me.
here is my code.
this my Main activity.

You have to use a ViewPager. Read more at Android Developer website. You can find a lot of custom view pagers on Android Arsenal. This is the current standard, so you should use this over TabHost.

you can have a look at its demo in eclips go to
file->other->android Activity->tabbed activity
or learn the view Fliper from android developer website

Use this method in your activity for all fragment trancation
// For the Fragment Replace And AddtobackStack
void replaceFragment(Fragment fragment) {
String backStateName = fragment.getClass().getName();
String fragmentTag = backStateName;
FragmentManager manager = this.getSupportFragmentManager();
boolean fragmentPopped = manager
.popBackStackImmediate(backStateName, 0);
if (!fragmentPopped && manager.findFragmentByTag(fragmentTag) == null) {
// fragment not in back stack, create it.
FragmentTransaction ft = manager.beginTransaction();
ft.replace(R.id.container, fragment, fragmentTag);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(backStateName);
ft.commit();
}
}
and use it like this whenever you need to go for nested fragment from one fragmnet
if (DetailsFragment.this.getActivity() != null
&& DetailsFragment.this.getActivity() instanceof HomeActivity)
((HomeActivity) DetailsFragment.this.getActivity())
.replaceFragment(cartfragment);
in the above suppose i am in details fragment and from here i want to go to cartfragment
then get the activitiy instance and cast it like the above

How do I use fragments properly

I'm trying to learn how to use Fragments in android. I create the separate classes and layouts. I'm having trouble understanding how I'm supposed to link them all. What exactly goes in my Main class? Could someone please demonstrate exactly how to use fragments in a very basic way?

please read this first as, i think, i has the very basics. Below is an example:
MainActivity:
public class MainActivity extends Activity implements OnClickListener{
private final String TAG = "MainActivity";
private int btn00Clicks = 0;
private int btn01Clicks = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainactivity);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Fragment mSelectedFragment = null;
switch (v.getId()) {
case R.id.btn00:
Bundle mBundle00 = new Bundle();
String clicks00 = Integer.toString(btn00Clicks);
mBundle00.putString("btn00_clicks", clicks00);
mSelectedFragment = new Fragment00();
mSelectedFragment.setArguments(mBundle00);
if (mSelectedFragment != null) {
FragmentManager mFragmentManager = getFragmentManager();
mFragmentManager.beginTransaction()
.replace(R.id.fragment00ID, mSelectedFragment).commit();
}
btn00Clicks++;
break;
case R.id.btn01:
Bundle mBundle01 = new Bundle();
String clicks01 = Integer.toString(btn01Clicks);
mBundle01.putString("btn01_clicks", clicks01);
mSelectedFragment = new Fragment01();
mSelectedFragment.setArguments(mBundle01);
if (mSelectedFragment != null) {
FragmentManager mFragmentManager = getFragmentManager();
mFragmentManager.beginTransaction()
.replace(R.id.fragment00ID, mSelectedFragment).commit();
}
btn01Clicks++;
}
}
}
Fragment00.java:
public class Fragment00 extends Fragment {
private final String TAG = "Fragment00";
TextView mTv;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub

In your main class you produce one or more fragments... While you produce each fragment it's pretty similar to Activity,but has its own lifecircle(google it).
here's example on fragment:
public class DummySectionFragment3 extends Fragment
{
public DummySectionFragment3() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.exercise_layout,
container, false);
return rootView;
}
}
in OnCreateView() method you do what you usually do with activity.
My Main class contains SectionsPagerAdapter that switches between the fragments(A pager like in API samples)
create 2 or 3 fragments and just try it...
I didn't find any good example on it,so I just tried the above.

http://www.c-sharpcorner.com/UploadFile/2fd686/fragments/
Here's one good link with tabs and fragments.
You can also define your fragments in your xml.

Same as what LetsAmrIt posted, just another example:

The basic is like this:
Create one Activity and 2 Fragments.
If something happens in FragmantA something should change in fragmentB right. So the Activity links Fragment A and B together. What do you need for that: an Interface.
So create an Interface with a method which takes the right properties (don't forget the datatype). Now you can implement the interface in your activity.
After this you should initialize the interface in FragmentA in the onActivityCreated method. Perform the changes and send the data to the interfacemethod in the Activity. Create a reference to FragmentB using the FragmentManager. Now you can send the data/changes to FragmentB.
I hope you understand this ;). cheers

I made a sample project that doesn't use ViewPager and all the weird stuff, just the link between Activity and Fragment here on Stack Overflow and the same thing on Code Review to demonstrate it, click either links to see the project.

I used this link to get started
http://www.techotopia.com/index.php/Using_Fragments_in_Android_-_A_Worked_Example
This guy uses 2 different types of listeners and takes in the user input on the first fragment. The 2nd fragment outputs the data!
Goodluck!

Issue with Fragment on Android Developer Page

I was reading the documentation on Fragment on the Developer site. I created a new project targeting api 8:android 2.2. I have the Android Support Library install, and I added the android support library to the project. I started implementing the helper method showDetails, and I get the red squiggly line saying that "a_item could not be resolved". I don't remember the instruction saying create an a_item variable or add a layout with a_item id.
In addition, in the detail activity, I am getting an error message too. (getFragmentManager().beginTransaction().add(android.R.id.content, details).commit();) It says "The method add(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, DetailsFragment)". Did I miss something in the instructions?
Here are my sample codes:
package com.example.fragmentlayout;
import android.app.Activity;

Here is the land and portrait layout

Perhaps, it's a mistake. The answer is here
https://code.google.com/p/android/issues/detail?id=54837
The author of linked message advises to replace code fragment
if (index == 0) {
ft.replace(R.id.details, details);
} else {
ft.replace(R.id.a_item, details);
}
with code fragment
if (index == 0) {
ft.add(R.id.details, details);
} else {
ft.replace(R.id.details, details);
}
or maybe just
ft.replace(R.id.details, details);

Your DetailsActivity should extend FragmentActivity
You should use getSupportFragmentManager()
If you nest fragments into other fragments consider using getChildFragmentManager()
(ok, i didn't look through all of the code, so not sure if 3 is applicable)

You need to use getSupportFragmentManager instead of getFragmentManager, because you are using support fragments.
The R.id.a_item references the id of the layout in your layout file. Instead of android:id="#+id/fragment1", make it android:id="#+id/a_item"

Android change tab without losing data

I'm working with tabs in android, according to my requirement I need to open a popup containing 5 tabs. That is, I have a Fragment where I have to open a DialogFragment and this DialogFragment need to show my 5 tabs. So far so quiet! Could enter each content on their respective tabs.
But the problem is that when I change the tab, the values ​​that were entered in another tab are clean. example:
I go into tab1 fills any value in a text field and then when I switch to tab2 tab1 back to the value it had before entered is lost.
Given this scenario, how do I retain the values ​​that were filled to the brim change? Follow the code below to explain further.

Thanks to all who tried to help me!
I do not have much experience with android but from what I saw, the classes must be executed according to the hierarchy proposed by android. That is, in my case I have a main activity which calls the mine fragments and through one of the fragments I had to call a DialogFragment and this would inflate DialogFragment several Views (my tabs), so I have the following structure:
Activity > Fragment > DialogFragment > Views
Based on this solution for my case was thus:
import android.app.Activity;
