i am working on android app which can play background sound whenever image is swipes. I have gone through multiple tutorials & found codes & i tried for the same but it won't work for me. Here is my code which i tried..
package com.android.learning_numbers;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
public class Numbers extends Activity {
private static final OnPageChangeListener change = null;
public static MediaPlayer mp = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_numbers);
ViewPager viewPager = (ViewPager)findViewById(R.id.view_pager);
ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
viewPager.setOnPageChangeListener(change);}
private class ImagePagerAdapter extends PagerAdapter {
private int[] mImages = new int[] {R.drawable.sun,R.drawable.sky,R.drawable.moon,};
private int[] mAudio= new int[]{R.raw.sun,R.raw.sky,R.raw.moon,};
#Override
public int getCount() {
return mImages.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
Context context = Numbers.this;
ImageView imageView = new ImageView(context);
int padding =context.getResources().
getDimensionPixelSize(R.dimen.activity_vertical_margin);
imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.CENTER);
imageView.setImageResource(mImages[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
public OnPageChangeListener change = new OnPageChangeListener() {
#Override public void onPageSelected(int position) {
Log.d(ACTIVITY_SERVICE, "OnPageSelected");
if
(mp != null) {
mp.reset();
mp.release();
}
mp = MediaPlayer.create(Numbers.this, mAudio[position]);
mp.start();
}
#Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}
#Override public void onPageScrollStateChanged(int state) {}
};
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
}
As i think here sound is not called by class on image swipe. Is there any error in my code? Because here OnPageChangeListener is not working for me at all. What is the solution for this? How do i modify my sound code that works for me?
Try this code & make changes according to your needs.. It works for me..
public class Alphabets extends Activity {
MediaPlayer mp;
MediaPlayer BG;

ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
myPager.setOnPageChangeListener(player);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
BG = MediaPlayer.create(this, R.raw.jingle);
BG.setLooping(true);
BG.setVolume(100, 100);
BG.start();
mp = MediaPlayer.create(Alphabets.this, mAudio[0]);
mp.start();
}
#Override
protected void onPause() {
super.onPause();
BG.pause();
}
#Override

super.onResume();
BG.start();
}

i have implemented an auto rotating banner with viewpager and handling images with arraylist but i want to open new activity on clicking to the banner which i had used i am not getting how to handle it listeners
Code :
package com.example.demoapp;
import android.os.Handler;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.viewpagerindicator.CirclePageIndicator;
import java.util.ArrayList;
import java.util.Timer;
import java.util.TimerTask;
public class MainActivity extends AppCompatActivity {
private static ViewPager mPager;
private static int currentPage = 0;
private static int NUM_PAGES = 0;
private ArrayList<ImageModel> imageModelArrayList;
private int[] myImageList = new int[]{R.drawable.ban, R.drawable.bann,
R.drawable.banne,R.drawable.banner
,R.drawable.banne,R.drawable.cover};

init();
}
public ArrayList<ImageModel> populateList(){

for(int i = 0; i < 6; i++){

imageModel.setImage_drawable(myImageList[i]);
list.add(imageModel);
}
return list;
}
private void init() {
mPager = (ViewPager) findViewById(R.id.pager);
mPager.setAdapter(new SlidingImage_Adapter(MainActivity.this,imageModelArrayList));
CirclePageIndicator indicator = (CirclePageIndicator)
findViewById(R.id.indicator);
indicator.setViewPager(mPager);
final float density = getResources().getDisplayMetrics().density;
//Set circle indicator radius
indicator.setRadius(5 * density);
NUM_PAGES =imageModelArrayList.size();
// Auto start of viewpager
final Handler handler = new Handler();
final Runnable Update = new Runnable() {
public void run() {
if (currentPage == NUM_PAGES) {
currentPage = 0;
}
mPager.setCurrentItem(currentPage++, true);
}
};
Timer swipeTimer = new Timer();
swipeTimer.schedule(new TimerTask() {
#Override

Needed help in onclick should open new activity.i had tried various thing but it doesn't worked for me.if anyone have alternative to implement auto rotating banner with on click should open new activity
Use a custom view pager class which can be clickable
public class ClickableViewPager extends ViewPager {
private OnItemClickListener mOnItemClickListener;
public ClickableViewPager(Context context) {
super(context);
setup();
}
public ClickableViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
setup();
}
private void setup() {
final GestureDetector tapGestureDetector = new GestureDetector(getContext(), new TapGestureListener());
setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
tapGestureDetector.onTouchEvent(event);
return false;
}
});
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
mOnItemClickListener = onItemClickListener;
}
public interface OnItemClickListener {
void onItemClick(int position);
}
private class TapGestureListener extends GestureDetector.SimpleOnGestureListener {
#Override
public boolean onSingleTapConfirmed(MotionEvent e) {
if(mOnItemClickListener != null) {
mOnItemClickListener.onItemClick(getCurrentItem());
}
return true;
}
}
}
and implement an anonymous type listener
ClickableViewPager viewPager = (ClickableViewPager) findViewById(R.id.viewPager);
viewPager.setOnItemClickListener(new ClickableViewPager.OnItemClickListener() {
#Override
public void onItemClick(int position) {
// your code
}
});
Refered from question ViewPager OnItemClickListener
I want to make an image slider with Android Studio.
I found a new slider code, built with ViewPager, I tried it and worked..
but I want to add 2 buttons for next and previous..
When clicked button, it must go to next picture or previous picture.
here the mainactivity,
package org.trial.slider;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImageAdapter adapter = new ImageAdapter(this);
viewPager.setAdapter(adapter);
}
}
ImageAdapter.java file,
package org.trial.slider;
import android.content.Context;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.ImageView;
/**
* Created by ismail on 30.03.16.
*/
public class ImageAdapter extends PagerAdapter {
Context context;
private int[] GalImages = new int[] {
R.drawable.one,
R.drawable.two,
R.drawable.three
};
ImageAdapter(Context context){
this.context=context;
}
#Override
public int getCount() {
return GalImages.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(context);
int padding = context.getResources().getDimensionPixelSize(R.dimen.padding_medium);
imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setImageResource(GalImages[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
And I have 2 XML files; fragment_pager and swipe_fragment
add button your MainActivity and activity_main.xml
add code button.setonclicklister(this); in OnCreate()
Example code here :
#Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
//prev button
case R.id.btn_list_detail_img_prev:
viewPager.setCurrentItem(mPager.getCurrentItem()-1,true);
break;
//nextbutton, 1st argument : pageindex, 2nd argument : Enable smooth
case R.id.btn_list_detail_img_next:
viewPager.setCurrentItem(mPager.getCurrentItem()+1,true);
break;
}
There is a method name viewPager.setCurrentItem(position).
This method take a integer value as a index and is set on viewPager object using this method you can change the position if pager item.
class MyClass extends Fragment implements ViewPager.OnPageChangeListener {
private int selectedViewPager = 0;
public void onViewClicked(View view) {
switch (view.getId()) {
case R.id.backward:
if (selectedViewPager > 0) {
viewPager.setCurrentItem(selectedViewPager - 1, true);
}
break;
case R.id.fwd:
if (viewPager.getAdapter().getCount() > selectedViewPager) {
viewPager.setCurrentItem(selectedViewPager + 1, true);
}
break;
}
}
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
selectedViewPager = position;
}
#Override
public void onPageScrollStateChanged(int state) {
}
}
I use PagerView in my application. But I have mistake. I load image in each pages. On all pages I see my images. but the page that has a position 0 in pagerAdapter is empty always. What I do not correctly?
public class MainActivity extends ActionBarActivity {
String TAG = "State";
static ViewPager pager;
static PagerAdapter pagerAdapter;
public static MainActivity activity;
static final int PAGE_COUNT = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

pager = (ViewPager) findViewById(R.id.pager);
pager.setOffscreenPageLimit(0);
final ArrayList<String> imagePaths = new ArrayList<String>();
imagePaths.add("http://tlt.ru/uploads/2014/05/94e1e91067997356912d68e0acc36d31_x240.jpg");

pagerAdapter = new FullScreenImageAdapter(activity, imagePaths);
pager.setAdapter(pagerAdapter);
pager.setOnPageChangeListener(new OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
//Log.d(TAG, "onPageSelected, position = " + position);

}

pagerAdapter.notifyDataSetChanged();
}
#Override

if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public static class FullScreenImageAdapter extends PagerAdapter {

How I can load image in page[0]?
I thikn the problem is in the getItemPosition, try this:
#Override
public int getItemPosition (Object object){
int index = _imagePaths.indexOf(object);
if (index == -1)
return POSITION_NONE;
else
return index;
}
The problem is with the position, you can find a better solution for pager here. You need to Modify activity_main.xml to include android.support.v4.view.ViewPager in layout.
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:autoLink="web"
android:text="http://android-er.blogspot.com/"
android:textStyle="bold" />
<android.support.v4.view.ViewPager
android:id="#+id/myviewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
And MainActivity.java

I am really stuck badly here. Please tell me where the error is.
I don't know exactly what your error is, but if you say that it's "by attaching OnPageChangeListener to my viewPager", I will tell you to do that :
Maybe try to get your OnPageChangeListener mOnPageListener out of your ImagePagerAdapter, put it directly in your Activity.
Or set the OnPageChangeListener to the adapter :
viewPager.setOnPageChangeListener(adapter);
and make your Adapter implement onPageChangedListener.
Hope it will help
I am getting this problem in my android application as an "value of the field is not in used".
actually i am trying to play the sound here when user swipes the page but it continuously giving me this error. this my code.
