I am working on an Android project in which I have to display some images in a list. For this, I am using an Adapter. I don't see any errors when I run the code, but no image is displayed. Also, I have set an onClickListener, and a Log.d inside it. But the Log.d is not displayed. What am I doing wrong?
public class OtherUsers extends Activity {
private PersonServiceImpl personService = new PersonServiceImpl();
private static volatile List<RestPerson> restPersonList = new ArrayList<>();
public static final String firstName = "firstname";
public static final String userImage = "userimage";
static final String userId = "0";
ListView listView;
UserAdapter userAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.displayuserlist);
restPersonList = this.personService.getOtherUsers();
ArrayList<HashMap<String, String>> usersArrayHashList = new ArrayList<>();
for (RestPerson restPerson : restPersonList) {
HashMap<String, String> restDisplay = new HashMap<>();
restDisplay.put(userId, String.valueOf(restPerson.getUserId()));
restDisplay.put(firstName, restPerson.getFirstName());
restDisplay.put(userImage, restPerson.getProfilePhoto());
usersArrayHashList.add(restDisplay);
}
listView = (ListView) findViewById(R.id.usersdisplaylist);
userAdapter = new UserAdapter(this, usersArrayHashList);
listView.setAdapter(userAdapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.d("Item", "wasclicked");
Long userid = restPersonList.get(position).getUserId();
Log.d("Userid is ", String.valueOf(userid));
}
});
}
}
Adapter class :
public class UserAdapter extends BaseAdapter {
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater = null;
public UserAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
data = d;
inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return data.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) {
View view = convertView;
if (convertView == null)
view = inflater.inflate(R.layout.userprofiles, null);
TextView username = (TextView) view.findViewById(R.id.userName);
ImageView userImage = (ImageView) view.findViewById(R.id.userImage);
HashMap<String, String> usersList = new HashMap<>();
usersList = data.get(position);
username.setText(usersList.get(OtherUsers.firstName));
byte [] encodeByte=Base64.decode(usersList.get(OtherUsers.userImage).getBytes(), Base64.DEFAULT);
Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
userImage.setImageBitmap(bitmap);
return view;
}
}
No image is seen, cant see in Log.d the clicked id. Unfortunately no errors to diagnose whats wrong.
Update
userprofiles.xml :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

PhotoSaving code :
public class AddPhotoForUser extends Activity {
private static final int CAMERA_PIC_REQUEST = 22;
Button BtnSelectImage;
private ImageView ImgPhoto;
private static volatile Bitmap photo;
private static volatile ByteArrayOutputStream stream = new ByteArrayOutputStream();
final PersonServiceImpl personService = new PersonServiceImpl();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.upload_user_photo);
Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
uploadImageButton.setVisibility(View.INVISIBLE);
ImgPhoto = (ImageView) findViewById(R.id.userPhotoImageView);
BtnSelectImage = (Button) findViewById(R.id.userPhotoButtonSelect);
BtnSelectImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
});
uploadImageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!(v == null)) {
uploadImage();
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
Intent intent = new Intent(AddPhotoForUser.this, RestaurantList.class);
startActivity(intent);
finish();
}
}
});
}
@Override
public void onBackPressed() {
Intent intent = new Intent(AddPhotoForUser.this, Login.class);
startActivity(intent);
finish();
}
@Override
public void onActivityResult(final int requestCode, int resultCode, Intent data) {
try {
switch (requestCode) {
case CAMERA_PIC_REQUEST:
if (resultCode == RESULT_OK) {
try {
photo = (Bitmap) data.getExtras().get("data");
if (!(photo == null)) {
ImgPhoto.setImageBitmap(photo);
Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
uploadImageButton.setVisibility(View.VISIBLE);
}
} catch (Exception e) {
Toast.makeText(this, "Couldn't load photo", Toast.LENGTH_LONG).show();
}
}
break;
default:
break;
}
} catch (Exception e) {
e.printStackTrace();
}
}
private void uploadImage() {
if (!(photo == null)) {
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
personService.addUserProfilePhoto(Base64.encodeToString(byteArray, Base64.DEFAULT));
}
}
}
Now , this calls the method to save it in DB. Currently, because byte-array was harassing so much, I have changed it to String. Here is how it looks in DB now :

Below methods are used to add photo and retrieve users from server :
