Android Full Screen images Slider with ViewPager

I want to an images slider inside my app!
after a long search I found that I have to use a ViewPager to get things done!
I need to make the Viewpager to be come full screen when I select image and slides left and right to show previous and next image in the slider..
here's my code :

and when I click to show the full screen fragment nothing popups without any errors?
how to fix that?
and If there any way to implement my idea feel free to guide me.
thanks in advance :)

I don't know how to update the button text from Pageviewer.java for the button with R.id.bookmark that shows up on the Bookmarks fragment on the click of menu item R.id.action_settings. I want to do this so that the button text corresponds to the page that is being bookmarked. I tried alot of things but to no avail. Can someone please help me with anything?
Thanks in advance

Create a method in your fragment to update the text of your button.
public void updateText(String newText){
//assuming button is globally declared in your fragment.
button.setText(newText);
}
Instead of Gesture Detector you could use a ViewPager which supports swiping to the left and right.You can find a sample implementation here.
Then in your Activty,implement PageChanegListener on ViewPager.
viewPager.addOnPageChangeListener(new OnPageChangeListener() {
public void onPageScrollStateChanged(int state) {}
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}
public void onPageSelected(int position) {
// Check if this is the page you want.You have to implement viewpager's adapter with getItem(index) which returns a fragment at that index.
BookMarkFragment fragment (BookMarkFragment)mAdapter.getItem(position);
fragment.updateText(newText);
};
});

You should save the state of a button somewhere. Your field int Bookmark == 0, so expression sendButton.setText("Page "+Pageno); never execute. Save the state in SharedPreferences and get this state. Like this:
prefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
int isBookmark = prefs.getInt("Bookmark", 0);
int mPageno = prefs.getInt("Pageno", 0);
...
if(isBookmark == 1){
sendButton.setText("Page " + mPageno);
} else {
sendButton.setText("No Bookmark");
}

cannot able to fetch Boolean value from the shared Preference

I have a checkbox , I want it to be unchecked by default. i.e False.
On manually checking the checkbox, i.e if the checkbox is checked , it perform certain action in another class.
I tried to save the sate of the checkbox using SharedPreference, but when I tried to fetch the checkbox value in another class using GetBoolean , I am not getting the saved value.

I have posted my code, any suggestion or advice will be of grate helpfull, as I am not able to understand where I am going wrong.

public static String KEY="Box";
private void savePreferences(boolean value){
SharedPreferences sharedpreferences = getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
Editor editor = sharedpreferences.edit();
editor.putBoolean(KEY,value);
editor.commit();
}
Retrieving End
SharedPreferences getpreferences = getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
boolean isChecked=getpreferences.getBoolean("Box",false);

I want to change from an xml layout to surfaceview using java

OK so I'm using xml to set this menu which is supported by the following java code
package starting.rt;
import java.util.List;
import java.util.Random;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class Menu extends Activity implements OnClickListener{
View.OnTouchListener gestureListener;
TextView display;
Button begin;
Button random;
Button game;
TextView counter;
Button next;
Button previous;
Button moreapps;
Button rate;
Random myRandom;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(starting.rt.R.layout.menu);
begin = (Button) findViewById(starting.rt.R.id.Begin);
random = (Button) findViewById(starting.rt.R.id.Random);
display = (TextView) findViewById(starting.rt.R.id.tvResults);
counter = (TextView) findViewById(starting.rt.R.id.tvCounter);
next = (Button) findViewById(starting.rt.R.id.Next);
previous = (Button) findViewById(starting.rt.R.id.Previous);
moreapps = (Button)findViewById(R.id.More);
rate = (Button) findViewById(R.id.rate);
game = (Button) findViewById(R.id.game);
// display.setOnTouchListener(this.gestureListener);
begin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent openStartingPoint = new Intent("starting.rt.RelationshipTipsActivity");
startActivity(openStartingPoint);
}});
moreapps.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent goToMarket;
goToMarket = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=pub:\"Wompa\""));
startActivity(goToMarket);
}});
game.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent openStartingPoint = new Intent("starting.rt.GameView");
startActivity(openStartingPoint);
}});
rate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("market://details?id=" + getPackageName()));
startActivity(i);
}});}
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
Now what's supposed to be happening is when they click on the game which starts a new java class called GameView it crashes on clicked. Every other button works.
This is the code from GameView
package starting.rt;
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class GameView extends SurfaceView {
private GameLoopThread gameLoopThread;
private List<Sprite> sprites = new ArrayList<Sprite>();
private List<TempSprite> temps = new ArrayList<TempSprite>();
private long lastClick;
private Bitmap bmpBlood;
public GameView(Context context) {
super(context);
gameLoopThread = new GameLoopThread(this);
getHolder().addCallback(new SurfaceHolder.Callback() {
public void surfaceDestroyed(SurfaceHolder holder) {
boolean retry = true;
gameLoopThread.setRunning(false);
while (retry) {
try {
gameLoopThread.join();
retry = false;
} catch (InterruptedException e) {}
}
}
public void surfaceCreated(SurfaceHolder holder) {
createSprites();
gameLoopThread.setRunning(true);
gameLoopThread.start();
}
public void surfaceChanged(SurfaceHolder holder, int format,
int width, int height) {
}
});
bmpBlood = BitmapFactory.decodeResource(getResources(), R.drawable.blood1);
}
private void createSprites() {
sprites.add(createSprite(R.drawable.bad1));
// sprites.add(createSprite(R.drawable.bad2));
// sprites.add(createSprite(R.drawable.bad3));
// sprites.add(createSprite(R.drawable.bad4));
// sprites.add(createSprite(R.drawable.bad5));
// sprites.add(createSprite(R.drawable.bad6));
// sprites.add(createSprite(R.drawable.good1));
// sprites.add(createSprite(R.drawable.good2));
// sprites.add(createSprite(R.drawable.good3));
// sprites.add(createSprite(R.drawable.good4));
// sprites.add(createSprite(R.drawable.good5));
// sprites.add(createSprite(R.drawable.good6));
}
private Sprite createSprite(int resouce) {
Bitmap bmp = BitmapFactory.decodeResource(getResources(), resouce);
return new Sprite(this, bmp);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.BLACK);
for (int i = temps.size() - 1; i >= 0; i--) {
temps.get(i).onDraw(canvas);
}
for (Sprite sprite : sprites) {
sprite.onDraw(canvas);
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (System.currentTimeMillis() - lastClick > 300) {
lastClick = System.currentTimeMillis();
float x = event.getX();
float y = event.getY();
synchronized (getHolder()) {
for (int i = sprites.size() - 1; i >= 0; i--) {
Sprite sprite = sprites.get(i);
if (sprite.isCollition(x, y)) {
sprites.remove(sprite);
temps.add(new TempSprite(temps, this, x, y, bmpBlood));
break;
}
}
}
}
return true;
}
}
The GameView calls a few other classes for things part of the game but it crashes before it can start. I think it's crashing because it's switching from xml layout to the java surfaceview. Help would be appreciated :) Thanks!

First of all, you should always post in your questions the stacktrace with the exception from the Logcat if your app crashes.
You can't start a SurfaceView directly, instead your custom SurfaceView must be embedded in an Activity like any other view in android. For example:
public class GameViewActivity extends Activity {
#Override
public void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
setContentView(new GameView(this));
}
}

Android Dashboard Layout with TabHost

I have search and could seem to find anything close to the issue I am having so I figured I would ask.
I have a Dashboard layout
This is all working correctly
What I want to do is have it work as shown below ( I have the Tabhost defined but I had to setup the class to extend TabActivity which breaks the ActionBar navigation )
The tabs correctly switch but it will not allow me to use any of the buttons on the action bar, and its not pulling the information correctly like it should be
the above works correctly. So I guess my question is how can I correctly add the TabHost to my classes and also have it Extend or Implement the Dashboard code? I have tried extends TabActivity implements Dashboard with no luck.
Here is my code thus far
Dashboard.java
package com.ondrovic.bbym;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.res.Configuration;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
public abstract class Dashboard extends Activity {
public static final boolean usePrettyGoodSolution = false;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public void onDestroy() {
super.onDestroy();
}
public void onPause() {
super.onPause();
}
public void onRestart() {
super.onRestart();
}
public void onResume() {
super.onResume();
}
public void onStart() {
super.onStart();
}
public void onStop() {
super.onStop();
}
public void onClickHome(View v) {
goHome(this);
}
public void onClickUpdate(View v) {
//startActivity(new Intent(getApplicationContext(), Update.class));
}
public void onClickAbout(View v) {
//startActivity(new Intent(getApplicationContext(), About.class));
}
public void goHome(Context context) {
final Intent intent = new Intent(context, Home.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(intent);
}
#Override
public void setContentView(int layoutID) {
if (!usePrettyGoodSolution) {
super.setContentView(layoutID);
return;
}
Configuration c = getResources().getConfiguration();
int size = c.screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK;
boolean isLarge = (size == Configuration.SCREENLAYOUT_SIZE_LARGE);
boolean isXLarge = (size == Configuration.SCREENLAYOUT_SIZE_XLARGE);
boolean addFrame = isLarge || isXLarge;
// if (isLarge) System.out.println ("Large screen");
// if (isXLarge) System.out.println ("XLarge screen");
int finalLayoutId = addFrame ? R.layout.large : layoutID;
super.setContentView(finalLayoutId);
if (addFrame) {
LinearLayout frameView = (LinearLayout) findViewById(R.id.frame);
if (frameView != null) {
// If the frameView is there, inflate the layout given as an
// argument.
// Attach it as a child to the frameView.
LayoutInflater li = ((Activity) this).getLayoutInflater();
View childView = li.inflate(layoutID, null);
if (childView != null) {
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT, 1.0F);
frameView.addView(childView, lp);
// childView.setBackgroundResource (R.color.background1);
}
}
}
}
public void setTitleFromActivityLabel(int textViewID) {
TextView tv = (TextView) findViewById(textViewID);
if (tv !=null) {
tv.setText(getTitle());
}
}
}
Individual.java
package com.ondrovic.bbym;
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class Individual extends TabActivity {
public void onCreate(Bundle savedSate) {
super.onCreate(savedSate);
setContentView(R.layout.individual);
TabHost tabHost = getTabHost();
TabSpec attspec = tabHost.newTabSpec("ATT");
attspec.setIndicator("AT&T", getResources().getDrawable(R.drawable.icons_att_tab));
Intent attIntent = new Intent(this, Individual_ATT.class);
attspec.setContent(attIntent);
TabSpec sprspec = tabHost.newTabSpec("SPRINT");
sprspec.setIndicator("SPRINT", getResources().getDrawable(R.drawable.icons_sprint_tab));
Intent sprIntent = new Intent(this, Individual_SPRINT.class);
sprspec.setContent(sprIntent);
TabSpec vzwspec = tabHost.newTabSpec("VERIZON");
vzwspec.setIndicator("VERIZON", getResources().getDrawable(R.drawable.icons_verizon_tab));
Intent vzwIntent = new Intent(this, Individual_VERIZON.class);
vzwspec.setContent(vzwIntent);
tabHost.addTab(attspec);
tabHost.addTab(sprspec);
tabHost.addTab(vzwspec);
}
}
Here is my individual.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/background1"
android:orientation="vertical" >
<include layout="#layout/title_bar" />
<include layout="#layout/tabs" />
</LinearLayout>
If there is any other code that needs to be post please let me know and thanks for the assistance

So I figured it out by doing the following. Even though there is probably a better way here is what I've got
Individual.java
package com.ondrovic.bbym;
import android.app.LocalActivityManager;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class Individual extends Dashboard {
TabHost mTabs;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.individual);
setTitleFromActivityLabel(R.id.title_text);
mTabs = (TabHost) findViewById(android.R.id.tabhost);
LocalActivityManager mLocalActivityManager = new LocalActivityManager(this, false);
mLocalActivityManager.dispatchCreate(savedInstanceState);
mTabs.setup(mLocalActivityManager);
TabSpec attspec = mTabs.newTabSpec("ATT");
attspec.setIndicator("AT&T", getResources().getDrawable(R.drawable.icons_att_tab));
Intent attIntent = new Intent(this, Individual_ATT.class);
attspec.setContent(attIntent);
TabSpec sprintspec = mTabs.newTabSpec("SPRINT");
sprintspec.setIndicator("SPRINT", getResources().getDrawable(R.drawable.icons_sprint_tab));
Intent sprintIntent = new Intent(this, Individual_SPRINT.class);
sprintspec.setContent(sprintIntent);
TabSpec verizonspec = mTabs.newTabSpec("VERIZON");
verizonspec.setIndicator("VERIZON", getResources().getDrawable(R.drawable.icons_verizon_tab));
Intent verizonIntent = new Intent(this, Individual_ATT.class);
verizonspec.setContent(verizonIntent);
mTabs.addTab(attspec);
mTabs.addTab(sprintspec);
mTabs.addTab(verizonspec);
}
}
Here's the result everything is working :-)
