recyclerview footer click to load images

I'm trying to achieve some thing like the image below. Here when recyclerview is empty it will show the camera imageview in footer and when I click on the image, I can select image from camera or gallery (which will be saved in an internal storage folder) and display them in recyclerview. But I'm getting ArrayIndexOutOfBoundsException in onBindViewHolder in case 1. How to display images from internal folder?
java.lang.ArrayIndexOutOfBoundsException: length=0; index=-1

share listview item (url image and text ) on facebook

I am fetching data from server and set it into listview. Each Listview item have photo ( url image ) and a text + share button . I have implemented all the code and working perfect.. But can any one help me.. How to implement facebook share intent when click on button of particular listview item.I want to share image and text
i ask from a way to the this
and thank you in advance

this is my code "MediaAdapter.java" :
public class MediaAdapter extends ArrayAdapter<Media> {
ArrayList<Media> mediaList;
Context context;
int Resource;
LayoutInflater vi;
ViewHolder holder;
ImageLoader imageLoader;
public MediaAdapter(Context context, int resource, ArrayList<Media> objects) {
super(context, resource, objects);
imageLoader = new ImageLoader(context);
vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Resource = resource;
mediaList = objects;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
// convert view = design
View v = convertView;
v = vi.inflate(Resource, null);
holder = new ViewHolder();
int loader = R.drawable.ic_launcher;
//l url d image
holder.imageview = (ImageView) v.findViewById(R.id.urlImage);
// load image
imageLoader.DisplayImage(mediaList.get(position).getUrl(), loader, holder.imageview );
holder.titre = (TextView) v.findViewById(R.id.titre);
holder.titre.setText(mediaList.get(position).getTitre());
v.setTag(holder);
holder.button = (Button) v.findViewById(R.id.btnOne);
holder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(v.getContext(), "test",Toast.LENGTH_SHORT).show();
}
});
return v;
}
static class ViewHolder {
public ImageView imageview;
public TextView titre;
public Button button;
}
}

Change this in the code ....
First remove this line from the constructor
imageLoader = new ImageLoader(context);
Change it to
ImageLoader imageLoader = ImageLoader.getInstance();
Secondly remove this line from the code :
imageLoader.DisplayImage(mediaList.get(position).getUrl(), loader, holder.imageview );
Change it to
imageLoader.loadImage(mediaList.get(position).getUrl(), new SimpleImageLoadingListener() {
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
holder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT,mediaList.get(position).getTitre());
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, getImageUri(context,loadedImage));
try {
context.startActivity(shareIntent);
} catch (Exception ex) {
Toast.makeText(context, ex.getMessage(),Toast.LENGTH_LONG).show();
}
}
});
}
});
Use this method to transform bitmap to uri:
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = Images.Media.insertImage(inContext.getContentResolver(),inImage, "Title", null);
return Uri.parse(path);
}
This will open the the share option for sharing to all the other apps including facebook. If facebook is selected by the user,then the image will be opened in the facebook app (if installed).Let me know if it working for you or not.

this is my new coode
it work like a charm
but i have a problem : but i have a problem when i click on share button of the item Number 2 ===== the content of the item number 3 is shared and note the Number 2 and vice-versa ????????????????
holder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Uri pictureUri = getLocalBitmapUri(holder.imageview);
if (pictureUri != null) {
// Construct a ShareIntent with link to image
String text = "image : "+mediaList.get(position).getTitre();
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, text);
shareIntent.putExtra(Intent.EXTRA_STREAM, pictureUri);
shareIntent.setType("image/*");
// Launch sharing dialog for image
shareIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(shareIntent);
} else {
// ...sharing failed, handle error

Android custom adapter list view images showing randomly while scroll

Hi i am a noob to android, I am trying to load some data to a ListView using custom adapter. I am using the following code for loading data. First time, it working well. But while I am trying to load more, then data loads and image is showing random while scrolling. After showing some random images in that list finally shows the correct image. It is repeating on the next scroll also
Here is my getView code
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
final ViewHolder holder;
if (v == null) {
LayoutInflater vi =
(LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.review_list_m, null);
v.setMinimumHeight(height);
holder = new ViewHolder();
holder.item1 = (TextView) v.findViewById(R.id.name);
holder.image = (ImageView) v.findViewById(R.id.posterView);
v.setTag(holder);
}
else
holder=(ViewHolder)v.getTag();
int colorPos = position % colors.length;
v.setBackgroundColor(Color.parseColor(colors[colorPos]));
final Custom custom = entries.get(position);
if (custom != null) {
holder.image.setBackgroundColor(Color.parseColor(colors[colorPos]));
holder.image.setLayoutParams(new LinearLayout.LayoutParams(height-10,width-10));
String imgUrl=custom.getImage();
AsyncHttpClient client = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
client.get(imgUrl, new BinaryHttpResponseHandler(allowedContentTypes) {
#Override
public void onSuccess(byte[] fileData) {
// Do something with the file
ByteArrayInputStream inputStream = new ByteArrayInputStream(fileData);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
holder.image.setImageBitmap(bitmap);
}
});
holder.item1.setHeight(height/3);
Log.v("PATH",custom.getcustomBig());
holder.item1.setText(custom.getcustomBig());
}
return v;
}
Any idea ? Please help

Problably you should set null bitmap to holder.image if v != null. Otherwise Android can show bitmap from other cell until new image is downloaded via async http request.
Example code (for problem with redownload images), it wasn't testes, but should give you idea how should it looks:
HashMap<String, Bitmap> cache = new HashMap<String, Bitmap>();
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//....
final Custom custom = entries.get(position);
if (custom != null) {
holder.image.setBackgroundColor(Color.parseColor(colors[colorPos]));
holder.image.setLayoutParams(new LinearLayout.LayoutParams(height-10,width-10));
String imgUrl=custom.getImage();
Bitmap cachedBitmap = cache.get(imgUrl);
if( cachedBitmap == null) {
AsyncHttpClient client = new AsyncHttpClient();
String[] allowedContentTypes = new String[] { "image/png", "image/jpeg" };
client.get(imgUrl, new BinaryHttpResponseHandler(allowedContentTypes) {
#Override
public void onSuccess(byte[] fileData) {
// Do something with the file
ByteArrayInputStream inputStream = new ByteArrayInputStream(fileData);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
holder.image.setImageBitmap(bitmap);
cache.add( imgUrl, bitmap );
}
});
}
else
{
holder.image.setImageBitmap(cachedBitmap);
}
holder.item1.setHeight(height/3);
Log.v("PATH",custom.getcustomBig());
holder.item1.setText(custom.getcustomBig());
}

EDITed answer
Validate your imageview's tag hasn't change before you set the Bitmap.
You could try:
/**
* Caches an image (or a group of them) async.
* #author
*
*/
public static class ImageCacher extends AsyncTask<String, String, Integer>{
Context context;
ImageView iv;
Bitmap b;
public ImageCacher(Context context, ImageView iv){
this.context = context;
this.iv = iv;
}
#Override
protected Integer doInBackground(String... params) {
for(final String param:params){
//check if already CACHED
String filename = String.format("%d", param.hashCode());
File file = new File(context.getFilesDir(), filename);
if(file.exists()){
try {
b = BitmapFactory.decodeFile(file.getAbsolutePath());
} catch (Exception e) {
}
if(b != null){
if(iv != null){
iv.post(new Runnable() {
public void run() {
String tag = (String) iv.getTag();
if(tag != null){
if(tag.matches(param))
iv.setImageBitmap(b);
}
}
});
}
return 0;
}else{
file.delete();
}
}
//download
file = new File(context.getFilesDir(), filename);
b = saveImageFromUrl(context, param);
if(b != null){
if(iv != null){
iv.post(new Runnable() {
public void run() {
String tag = (String) iv.getTag();
if(tag != null){
if(tag.matches(param))
iv.setImageBitmap(b);
}
}
});
}
}
}
return 0;
}
}
/**
* Gets an image given its url
* #param param
*/
public static Bitmap saveImageFromUrl(Context context, String fullUrl) {
Bitmap b = null;
try {
URL url = new URL(fullUrl);
URLConnection conn = url.openConnection();
conn.setDoInput(true);
conn.connect();
//save bitmap to file
InputStream is = conn.getInputStream();
String filename = String.format("%d", fullUrl.hashCode());
File file = new File(context.getFilesDir(), filename);
if(file.exists()){
//delete
file.delete();
file=null;
}
file = new File(context.getFilesDir(), filename);
FileOutputStream out = new FileOutputStream(file);
byte buffer[] = new byte[256];
while(true){
int cnt = is.read(buffer);
if(cnt <=0){
break;
}
out.write(buffer,0, cnt);
}
out.flush();
out.close();
is.close();
b = BitmapFactory.decodeFile(file.getAbsolutePath());
} catch (Exception e) {
e.printStackTrace();
}
return b;
}
/**
* Gets an already cached photo
*
* #param context
* #param fullUrl
* #return
*/
public static Bitmap getCachedPhoto(Context context, String fullUrl){
System.gc();
String filename = String.format("%d", fullUrl.hashCode());
File file = new File(context.getFilesDir(), filename);
if(file.exists()){
try {
Bitmap b = BitmapFactory.decodeFile(file.getAbsolutePath());
return b;
} catch (Exception e) {
}
}
return null;
}
And then, to set the image in the adapter, you can do like:
//set info
vh.iv.setTag("");
String foto = your_url_goes_here;
vh.iv.setImageResource(R.drawable.fotodefault_2x);
if(!TextUtils.isEmpty(foto)){
vh.iv.setTag(foto);
Bitmap b = getCachedPhoto(context, foto);
if(b != null){
vh.iv.setImageBitmap(b);
}else{
new ImageCacher(context, vh.iv).execute(foto);
}
}
Don't forget to correctly encapsulate the class and methods.
Hope it helps.

I had this random pictures problem with my arrayAdapter. Then I used Picasso which takes care of imageView reusing in listview: http://square.github.io/picasso/
Example of code:
Picasso.with(mContext)
.load(url)
.resize(size, size)
.centerCrop()
.placeholder(R.drawable.image_holder)
.into(holder.imgDefaultImage);

Check when onClick is checked only?

I have a checkbox, that when checked, makes a bitmap and then saves that bitmap to internal storage. Then, in a gridView adapter, I have it check for the bitmap from internal storage with FileInputstream.
The issue is that the checkbox's onClick method is also in a class that extends baseadapter.
With the way it is now, when I start my app, it automatically checks for the bitmap and then returns a FileNotFound exception and then the onClick of the checkbox doesn't do anything.
I thought about this and realized that the reason it checks for it is that it is creating the gridView when I first open my app (which it is supposed to). In other words, it checks for the file because it is in the getView() method of my gridView adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// Try to reuse the views
ImageView view = (ImageView) convertView;
// if convert view is null then create a new instance else reuse it
if (view == null) {
view = new ImageView(Context);
Log.d("GridViewAdapter", "new imageView added");
}
try {
Bitmap bitmapA = null;
FileInputStream in = Context.openFileInput("bitmapA");
bitmapA = BitmapFactory.decodeStream(in);
in.close();
/*BufferedInputStream buf = new BufferedInputStream(in);
byte[] bitMapA = new byte[buf.available()];
buf.read(bitMapA);
Bitmap bM = BitmapFactory.decodeByteArray(bitMapA, 0, bitMapA.length);
*/view.setImageBitmap(bitmapA);
if (in != null) {
in.close();
}
/*if (buf != null) {
buf.close();
}*/
} catch (Exception e) {
e.printStackTrace();
}
view.setImageResource(drawables.get(position));
view.setScaleType(ImageView.ScaleType.CENTER_CROP);
view.setLayoutParams(new android.widget.GridView.LayoutParams(70, 70));
view.setTag(String.valueOf(position));
return view;
}
Is there a way that I can make it check internal storage ONLY IF the checkbox is checked?
Please note that the onClick method of the checkbox is in one class while I am getting the bitmap in another.
Here are my two full classes:
AppInfoAdapter (the one with the onClick method---I will only post the needed coding here):

if (in != null) {
in.close();
}
/*if (buf != null) {

}*/
} catch (Exception e) {
e.printStackTrace();
}}
PLUS I ADDED THIS METHOD:
public void setCheckBox(CheckBox checkbox){
mCheckBox=checkbox;
}
AND THIS VARIABLE:
CheckBox mCheckBox=null;

You dont need to listen to the onClick event in the adapter.
Instead, you can read the checkbox status.
for this, in your adapter, you add a field and a setter:
CheckBox mCheckBox=null;
public void setCheckBox( CheckBox checkbox){
mCheckBox=checkbox;
}
and then, in the getView(), you add thiss line at the begining;
boolean checked = (mCheckBox==null)?false:(((CheckBox) mCheckBox).isChecked());
UPDATE
then in your activity, i suppose you have something like
GridViewAdapter mGridViewAdapter= new GridViewAdapter(this);
so, below you have to add:
CheckBox mCheckBox = findViewById(R,id.YOURCHECKBOXID);
mGridViewAdapter.setCheckBox(mCheckBox);
And that's it!
