I have a recycle View android and there's an image in each item. In that image i want to make a upload function. And I use MVP in this app. SO, There's a fragment, presenter and adapter.
My Fragment
public void loadList() {
rv.setAdapter(new PendingOrderAdapter(transactionHistories, getContext(), presenter));
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 0:
if (resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
file = new File(picturePath);
}
}
}
My Adapter
public class PendingOrderAdapter extends RecyclerView.Adapter<PendingOrderAdapter.PendingOrderHolder> {
ArrayList<TransactionHistory> list;
Context context;
File file;
PendingOrderPresenter presenter;
public PendingOrderAdapter(ArrayList<TransactionHistory> list, Context context, PendingOrderPresenter presenter) {
this.list = list;
this.context = context;
this.presenter = presenter;
}
#Override
public PendingOrderAdapter.PendingOrderHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_pending_order, parent, false);
return new PendingOrderAdapter.PendingOrderHolder(itemView);
}
#Override
public void onBindViewHolder(PendingOrderAdapter.PendingOrderHolder holder, int position) {
final TransactionHistory item = list.get(position);
holder.txvPackageName.setText(item.getPackageName());
holder.txvTransactionType.setText(item.getTransactionType());
holder.txvOrderNumber.setText(item.getOrderNumber());
holder.txvInvestmentNumber.setText(item.getInvestmentNumber());
holder.txvTotal.setText(AmountFormatter.format(item.getAmount()));
holder.txvTransactionStatus.setText(item.getTransactionStatus());
SimpleDateFormat sdf = new SimpleDateFormat(DateUtil.INVISEE_RETURN_FORMAT2, Locale.getDefault());
Date dateParse = null;
try {
dateParse = sdf.parse(item.getTransactionDate());
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy HH:mm" , Locale.getDefault());
String convertedDate= formatter.format(dateParse);
holder.txvDate.setText(convertedDate);
holder.imgOrder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
Activity origin = (Activity) context;
origin.startActivityForResult(i, 0);
}
});
presenter.uploadTransaction(item.getOrderNumber(), file);
}
#Override
public int getItemCount() {
return list != null ? list.size() : 0;
}
public static class PendingOrderHolder extends RecyclerView.ViewHolder {
#Bind(R.id.txvDate)
TextView txvDate;
#Bind(R.id.txvTransactionType)
TextView txvTransactionType;
#Bind(R.id.txvPackageName)
TextView txvPackageName;
#Bind(R.id.txvOrderNumber)
TextView txvOrderNumber;
#Bind(R.id.txvInvestmentNumber)
TextView txvInvestmentNumber;
#Bind(R.id.txvTotal)
TextView txvTotal;
#Bind(R.id.txvTransactionStatus)
TextView txvTransactionStatus;
#Bind(R.id.imgOrder)
ImageView imgOrder;
public PendingOrderHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
}
The question is how to bring image file to my adapter?

Listview is setting the filename only in first position. Even though on clicking any positions of the listview it sets the filename for the first position only. Please let me know what changes i need to make so that filename will be set properly on clicked item only instead of first item always. Thanks in advance.
I have done same with in Recycle view I am sharing my project code with you

}
}
public void Document(int pos) {
position = pos;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
startActivityForResult(intent, position);
}
#Override

String displayName = null;
if (data != null) {

String uriString = null;
if (uri != null) {

}
File myFile = new File(uriString);
String path = myFile.getAbsolutePath();
if (uriString != null) {
if (uriString.startsWith("content://")) {

I am making an application to save images. There is no problem when adding an image from the application's camera and the gallery image. But when I added a photo directly from the phone camera, it was not possible.
Error "Couldn't read row 0, col 0 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it." encountered in the code line "int id = cursor.getInt (0);" of MainActivity java class.
How to solve ?

First, I'm sorry for my bad English. please excuse me. :)..
I tried to make a custom listView which has ImageView, TextViews, and Button.
So, I want to change image after I click ImageView in listview and select image from gallery. But.. It's really hard to me.
In my code(customAdapter)Adapter class is not Activity, So it cannot call startActivityForResult directly. So I make new Activity(It is GalleryImage.java). and call startActivity using that class. But it is not working. What should I do...
(Error occur in ImageView.setOnClickListner, getView of PhoneBookAdapter)

Thanks for your help. :D.
Solution here is not creating a new instance of Activity but being able to access already existing instance created by Android Framework. Instance of an Activity should never be created by an application programmer.
Best approach would be to add a parameter of type Activity to the constructor of PhoneBookAdapter. Such as:
private Activity activity;
public PhoneBookAdapter(Activity activity, ArrayList<Contact> people) {
this.activity = activity;
m_people = people;
m_filteredPeople = people;
}
You can than then call activity.startActivityForResult on this instance of Activity.
You then pass in the instance of Activity when you create the adapter. In Activity you would simply pass this and in Fragment you can obtain the instance by calling getActivity() method of Fragment class.
As to processing the result of the started Activity you would need to implement this in the Activity or Fragment in which you display the list.
I have a listview which contains two buttons, when the button is clicked it should open a gallery. I tried to implement it and followed some post on stackoverflow but still I'm not able to get exact result. How to open the gallery using buttons in listViewlistview?
I have tried the following and used the adapter class as inner class
MyAdapter adapter=new MyAdapter(getApplicationContext(),videoFileList);
im my adapter class
private class MyAdapter extends BaseAdapter
{
ImageView picture;
Button imgbtn,videobtn;
ImageButton play;
Context context;
private LayoutInflater inflater;
private ArrayList<String> videolisty;
public MyAdapter(Context context,ArrayList<String> videolistx)
{
this.context=context;
inflater = LayoutInflater.from(context);
videolisty = videolistx;
Field[] arrayOfField = R.raw.class.getFields();
for (int i = 0; ; i++)
{
if (i >= arrayOfField.length)
{
System.out.println("-----------videolist------" +videoFileList);
return;
}
System.out.println("audio files-----" + arrayOfField[i].getName());
videoFilename.add(arrayOfField[i].getName());
Uri localUri = Uri.parse("android.resource://" + Listmodels.this.getPackageName() + "/" + "R.raw." + arrayOfField[i].getName());
System.out.println("--------uri path------" + localUri);
}
}
#Override
public int getCount() {
return videolisty.size();
}
#Override
public Object getItem(int i)
{
return videolisty.get(i);
}
#Override
public long getItemId(int i)
{
return i;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup)
{
View v = view;
final int xx = i;
if(v == null)
{
v = inflater.inflate(R.layout.clistview, viewGroup, false);
v.setTag(R.id.categoryimageView1, v.findViewById(R.id.categoryimageView1));
v.setTag(R.id.uploadimg, v.findViewById(R.id.uploadimg));
v.setTag(R.id.uploadvideo, v.findViewById(R.id.uploadvideo));
v.setTag(R.id.play, v.findViewById(R.id.play));
}
picture = (ImageView)v.getTag(R.id.categoryimageView1);
imgbtn = (Button)v.getTag(R.id.uploadimg);
videobtn = (Button)v.getTag(R.id.uploadvideo);
play=(ImageButton)v.getTag(R.id.play);
imgbtn.setOnClickListener(new OnClickListener() {
