I'm using an implementation of ViewFlow example for my application where I have to swipe images from SdCard. With the code I'm using I can swipe images, but it's showing only one and i'm trying to set the whole images from my SdCard specific folder in the ViewFlow, but that's the problem that I have. I'm getting the path to the image by an ID which I get from sqlite database and depending on that I want to add these images to the view. So this is the code which I'm using for now :
My Cards.class :
package com.stampii.stampii.cards;
import java.util.ArrayList;
import java.util.HashMap;
import com.stampii.stampii.R;

"ON (cm.cardId = cd.objectId) "+
"WHERE cd.collectionId="+collId +" AND cm.mediaType="+mediaType;
Cursor cards = userDbHelper.executeSQLQuery(cardSQL);
if (cards.getCount() == 0) {
Log.i("", "No Image file");
cards.close();
} else if (cards.getCount() > 0) {

Cursor cursor = userDbHelper.executeSQLQuery(sql);
if (cursor.getCount() == 0) {
Log.i("", "No Image file");
cursor.close();
} else if (cursor.getCount() > 0) {
cursor.moveToFirst();
objectId = Integer.parseInt(cursor.getString(cursor
.getColumnIndex("objectId")));
Log.i("", "objectId : " + objectId);
path = hm.get(objectId);
Log.i("","path : "+hm.get(objectId));
Log.i("","hm size : "+hm.size());
}
Button info = (Button) findViewById(R.id.info_button);
info.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Cards.this, SingleCardInfo.class);
intent.putExtra("card_id", cardId);

startActivity(intent);
}
});
Button back = (Button) findViewById(R.id.back_button);
back.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
final ArrayList<Bitmap> images = new ArrayList<Bitmap>();
for(int i=0;i<=2;i++){
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[16*1024];
Bitmap b = BitmapFactory.decodeFile(hm.get(objectId), options);
Log.i("","path : "+hm.get(objectId));
images.add(b);
}
viewFlow = (ViewFlow) findViewById(R.id.viewflow);
viewFlow.setAdapter(new ImageAdapter(this, images),position);
ImageButton prevBtn = (ImageButton) findViewById(R.id.previous_button);
prevBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
indexxx = viewFlow.getSelectedItemPosition()-1;
if (indexxx>=0) {
viewFlow.setAdapter(new ImageAdapter(Cards.this, images),indexxx);
viewFlow.setSelectedItemPosition(indexxx);
Log.i("indexxx", "indexxx : " + indexxx);
}
}
});
ImageButton nextBtn = (ImageButton) findViewById(R.id.next_button);
nextBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
indexxx = viewFlow.getSelectedItemPosition()+1;
if (indexxx<images.size()) {
viewFlow.setAdapter(new ImageAdapter(Cards.this, images),indexxx);
viewFlow.setSelectedItemPosition(indexxx);
Log.i("indexxx", "indexxx : " + indexxx);
}
}
});
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
viewFlow.onConfigurationChanged(newConfig);
}
}
And my ImageAdapter class :
package com.stampii.stampii.cards;
import java.util.ArrayList;
import com.stampii.stampii.R;
import android.content.Context;
import android.graphics.Bitmap;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<Bitmap> ids = new ArrayList<Bitmap>();
//private Bitmap bitmap;
public ImageAdapter(Context context, ArrayList<Bitmap> images) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ids = images;
}
#Override
public int getCount() {
return ids.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.image_item, null);
}
((ImageView) convertView.findViewById(R.id.imgView)).setImageBitmap(ids.get(position));
return convertView;
}
}
So my question is how can I add all images from my SdCard folder to this ViewFlow example when I had the path to these images. I've tried to load all of them, but in some cases the images are too much and it's throwing me an outofmemoryException, that's why I think it's better just to set the paths to them. So any help or suggestions are welcomed!
Thanks in advance!
Here is code of ViewFlow.class : ViewFlow
You can try something like this :
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<String> ids = new ArrayList<String>();
//private Bitmap bitmap;
public ImageAdapter(Context context, ArrayList<String> images) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ids = images;
}
#Override
public int getCount() {
return ids.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.image_item, null);
}
BitmapFactory.Options options = new BitmapFactory.Options();
options.inTempStorage = new byte[8*1024];
Bitmap ops = BitmapFactory.decodeFile(ids.get(position), options);
((ImageView) convertView.findViewById(R.id.imgView)).setImageBitmap(ops);
return convertView;
}
}
And :
public class Cards extends Activity {
public Cursor cursor;
int position;
int indexxx;
Bitmap b;
int objectId;
int cardsId;
ArrayList<Integer> ids;
String path;
int mediaType=5001;

}
});
Button info = (Button) findViewById(R.id.info_button);

That should do the trick!

i have a custom listview and custom adapter. each row has multiple items inside it, when i click on like button it change the color of imageview but it also effect the 4th,7th and 10th row.
after searching on internet i learned that i have to use getTag and setTag but i dont know how to use it.

This is because of object reuse in your list view.
You can manage separate ArrayList or HashMap to maintain your likes.
And based on that you should update in your getView like this,
if([already selected]) {
viewHolder.likebtn.setBackground([your selected drawable]);
} else {
viewHolder.likebtn.setBackground([your non selected drawable]);
}
This is my Apps Screenshoot :
There is two button in that GridView : +/-.
So what im gonna try is when i press "+" button or "-" button, the quantity is store in SharedPreferences.
But really im confused about this.
This is my code so far :

}
you are using custom array list of object than set propertie to it and on back press of application you can jsonify your object to string and store it in shared preference and at activity on create you can regenerate your object getting from shared preference. in activity onCreate()
SharedPreferences mSettings = PreferenceManager.getDefaultSharedPreferences
(Dashboard.this);
String data = mSettings.getString("data", "");
/* Should Activity Check for Updates Now? */
if ((data.equals(""))) {
//do nothing data is not in shared preference
}
else {
//data is there convert To object
data=mSettings.getString("data", "");
Type listType = new TypeToken<ArrayList<ListRowItem>>() {
}.getType();
ArrayList<ListRowItem> listRowItems = new Gson().fromJson(data, listType);
//setAdapter coming for arrayList as usual.
}
and in backPressed you can read data from adapter and jsonify it using json and put it in sharedPreference
i hope you understand the login . clear preference after data set.
Your issue is here:
holder.qty.setText(store);
It is clearly pointed out in your error log:
android.content.res.Resources$NotFoundException: String resource ID
0x1 at android.content.res.Resources.getText(Resources.java:1409) at android.widget.TextView.setText(TextView.java:4943)
store is an integer and setText is trying to look for a resource with this id. Use this instead.
holder.qty.setText(store.toString());
Also, to reduce the complexity of shared preferences specific code you can use this library

Now the result based on selection goes to main activity where I need to display all the selected images in a listview.
This is what I'm trying to do
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if(requestCode == PICK_IMAGE_MULTIPLE){
imagesPathList = new ArrayList<String>();
String[] imagesPath = data.getStringExtra("data").split("\\|");
try{
lnrImages.removeAllViews();
}catch (Throwable e){
e.printStackTrace();
}
for (int i=0;i<imagesPath.length;i++){
//Toast.makeText(MainActivity.this,String.valueOf(imagesPath.length),Toast.LENGTH_LONG).show();
imagesPathList.add(imagesPath[i]);
//Toast.makeText(MainActivity.this,imagesPathList.toString(),Toast.LENGTH_LONG).show();
yourbitmap = BitmapFactory.decodeFile(imagesPath[i]);
ImageView imageView = new ImageView(this);
imageView.setImageBitmap(yourbitmap);
imageView.setAdjustViewBounds(true);
//lnrImages.addView(imageView);
Uri uri = (Uri.fromFile(new File(imagesPath[i])));
filename = uri.getLastPathSegment();
//Toast.makeText(MainActivity.this,filename,Toast.LENGTH_LONG).show();
Uri selectedImage = data.getData();
encodedImage= bitmapToBase64(yourbitmap);
//Toast.makeText(MainActivity.this,encodedImage,Toast.LENGTH_LONG).show();
myStringList.add(filename);
myStringArray = myStringList.toArray();
lv.setAdapter(null);
Toast.makeText(MainActivity.this,(String)myStringArray[i],Toast.LENGTH_LONG).show();
arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
myStringList );
lv.setAdapter(arrayAdapter);
arrayAdapter.notifyDataSetChanged();
}
}
}
}
Now my problem is:
1) If I select one single image it's showing me the toast with the filename but not adding it to the listview
2)If I select two images its adding to the list view as normal
3) If I select more than two its appending to the old list(ie..adding the newly selected images to the previously selected images) though I have set the adapter to 'NULL'
4) Selecting large number of images takes time consumption to adding it to the listview crashing the app due to memory.
So can anyone suggest me the best way of handling this ?
Thanks in Advance!
There are multiple problems in your code. As in Java everything is reference, so instead of creating the adapter again and again, you should only set the new list to the adapter and then should call notifyDataSetChanged. For example, your ImageAdapter should be like this
public class ImageAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<String> imagesList = new ArrayList<>();
public void updateImagesList(ArrayList<Strinf> newImages) {
if(newImages != null && newImages.size() > 0) {
this.imagesList.clear();
this.imagesList.addAll(newImages);
}
}
}
and then you should create global Adapter variable which we will be using for future list updates
and in your onActivityResult, you should populate the strings list in a loop and then after the loop you should update the adapter list as
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == PICK_IMAGE_MULTIPLE) {
for (int i = 0; i < imagesPath.length; i++) {
//Toast.makeText(MainActivity.this,String.valueOf(imagesPath.length),Toast.LENGTH_LONG).show();
imagesPathList.add(imagesPath[i]);
//Toast.makeText(MainActivity.this,imagesPathList.toString(),Toast.LENGTH_LONG).show();
yourbitmap = BitmapFactory.decodeFile(imagesPath[i]);
ImageView imageView = new ImageView(this);
imageView.setImageBitmap(yourbitmap);
imageView.setAdjustViewBounds(true);
//lnrImages.addView(imageView);
Uri uri = (Uri.fromFile(new File(imagesPath[i])));
filename = uri.getLastPathSegment();
//Toast.makeText(MainActivity.this,filename,Toast.LENGTH_LONG).show();
Uri selectedImage = data.getData();
encodedImage = bitmapToBase64(yourbitmap);
//Toast.makeText(MainActivity.this,encodedImage,Toast.LENGTH_LONG).show();
myStringList.add(filename);
Toast.makeText(MainActivity.this, (String) myStringArray[i], Toast.LENGTH_LONG).show();
}
arrayAdapter.updateImages(myStringList);
arrayAdapter.notifyDataSetChanged();
}
}
}
Apart the above two changes, there is great performance impact because you are all doing I/O operations on Ui Thread as you are decoding Bitmap files on Main thread which is not the good approach as It will cause OutOfMemoryError as well as It will slow down your application. You should do bitmap operations or displaying using Universal Image Loader https://github.com/nostra13/Android-Universal-Image-Loader
Hope this helps.

I guess that the cause of this problem is context equal to null got from the method getActivity, but don't know how to deal with this problem. Could anyone explain how to solve the problem?
I think onActivityCreated method override and implement for this code, and its working fine may be...
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
if(getActivity()!=null){
load();
}
}
And Fragment lifecyle must read for this doc Documentation
Most likely your Fragment is detached from your activity at this stage as this is called in an external thread JsonHttpResponseHandler.
You have a good explanation here:
https://stackoverflow.com/a/11536337/891479
You should not call
if(getActivity()!=null){
load();
}
in onCreateView.
onViewCreated is called after onCreateView and as per the docs
The fragment's view hierarchy is not however attached to its parent
at this point.
I think if I remember correctly its better to use getActivity().getApplicationContext()

use getListview() in list Activity to get List..........
in Oncreate
ListView lv = getListView();
http://www.mkyong.com/android/android-listview-example/
this link has both ways
1- overriding onListItemClick(
2- Setting you listener..
Try this way..
ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
}
this are help you.
Thanks
Override the function onlistitemclick() for this. Here the integer position represents the postion of item that you had pressed
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
.......
}
Try this one
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
}
});
