How do I bind images from gallery to imageView at runtime?

How do I bind images from gallery to imageView at runtime? - android

I have a homework about doing whatsapp clone. But I have a problem. I have a add contact screen. Users choose an image from gallery and enter their name. When they click add button, list item will be added to chat activity. Screenshot is below. I have a person class like:
public class Person
{
private int id;
private string name;
private int imageId;
public Person(int id, string name, int imageId)
{
this.id = id;
this.name = name;
this.imageId = imageId;
}
public int Id // property
{
get { return id; } // get method
set { id = value; } // set method
}
public string Name // property
{
get { return name; } // get method
set { name = value; } // set method
}
public int ImageId // property
{
get { return imageId; } // get method
set { imageId = value; } // set method
}
public static explicit operator Java.Lang.Object(Person v)
{
throw new NotImplementedException();
}
}
public class PersonAdapter : BaseAdapter
{
private LayoutInflater mInflater;
private List<Person> personArrayList;
public PersonAdapter(Activity activity, List<Person> personArrayList)
{
this.mInflater = (LayoutInflater)activity.GetSystemService(Context.LayoutInflaterService);
this.personArrayList = personArrayList;
}
public override int Count => personArrayList.Count;
public override Object GetItem(int position)
{
return (Object)personArrayList.ElementAt(position);
}
public override long GetItemId(int position)
{
return position;
}
public override View GetView(int position, View convertView, ViewGroup parent)
{
convertView = mInflater.Inflate(Resource.Layout.List_Item, null);
TextView personName = (TextView)convertView.FindViewById(Resource.Id.name);
TextView personMessage = (TextView)convertView.FindViewById(Resource.Id.message);
ImageView personImage = (ImageView)convertView.FindViewById(Resource.Id.imageView);
Person person = personArrayList.ElementAt(position);
personName.Text = person.Name;
if(MainActivity.messages[person.Id].Count != 0)
{
personMessage.Text = MainActivity.messages[person.Id][MainActivity.messages[person.Id].Count - 1];
}
else
{
personMessage.Text = "";
}
personImage.SetImageResource(person.ImageId);
return convertView;
}
}
}
I have a personAdapter class and chat activity has only listView. So I am binding list to listView via adapter. I added some person manually to see chat menu. If I add images to drawable folder, there is no problem. But how do I add images to create new person. I can't add images to drawable at runtime. When I try to read images from external storage. They have no resource id. So person class do not accept that.

ListView listView = (ListView)FindViewById(Resource.Id.listView);

listView.Adapter = adapter;
listView.ItemClick += (object sender, ItemClickEventArgs e) =>
{

adapter.NotifyDataSetChanged();
}
}

public static int SELECT_IMAGE = 1001;

{

StartActivityForResult(Intent.CreateChooser(Intent, "Select Picture"), SELECT_IMAGE);
}
else
{

}
}
protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
{
if ((requestCode == SELECT_IMAGE) && (resultCode == Result.Ok) && (data != null))
{
Android.Net.Uri uri = data.Data;
Bitmap bitmap = MediaStore.Images.Media.GetBitmap(ContentResolver, uri);
imageView.SetImageBitmap(bitmap);
}
else
{
Toast.MakeText(this.ApplicationContext, "You haven't picked an image", ToastLength.Short).Show();
}
}
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults)
{
if (requestCode == 12)
{
if ((grantResults.Length == 1) && (grantResults[0] == Permission.Granted))
{
Intent = new Intent();
Intent.SetType("image/*");
Intent.SetAction(Intent.ActionGetContent);
StartActivityForResult(Intent.CreateChooser(Intent, "Select Picture"), SELECT_IMAGE);
}
}
else
{
base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
}

Do you want to achieve the result like this GIF?
Based on your code, you need serveral steps to achieve it.
First of all, we should use Convert Bitmap to Base64 string to achieve it, we can create a MyUtils.cs
public class MyUtils
{
public static string ConvertBitMapToString(Bitmap bitmap)
{
byte[] bitmapData;
using (MemoryStream stream = new MemoryStream())
{
bitmap.Compress(Android.Graphics.Bitmap.CompressFormat.Jpeg, 50, stream);
bitmapData = stream.ToArray();
}
string ImageBase64 = Convert.ToBase64String(bitmapData);
return ImageBase64;
}
public static Bitmap ConvertStringToBitmap(string mystr)
{
byte[] decodedString = Base64.Decode(mystr, Base64.Default);
Bitmap decodedByte = BitmapFactory.DecodeByteArray(decodedString, 0, decodedString.Length);
return decodedByte;
}
}
Then we should change the type of ImageId to string like following code.
public string ImageId // property
{
get { return imageId; } // get method
set { imageId = value; } // set method
}
Please change set the Image way in MainActiviy and Adapter.
Here is my demo, you can download it and refer to it.

How to pass editText data to a string URL

I Want to make a url in one of my activities(UploadActivity.java) by taking information from 3 edit text boxes in another activity (LoginActivity.java) and passing that data into the other activity,
All the questions i found here on SO only prtains to a static URL i.e. www.blahblah.com/blah-blah.asp?My=Yes etc.
basicly the user must input his email, password and client ID(made by my company) and then it must be consolidated into a string
like this one
public static final String UPLOAD_URL =
"https://www.smartpractice.co.za/files-upload-ruben.asp?clientID=6868";
I'm using above url to upload user's location to the server.
Must I declare the edittext boxes in the activity? because at the moment it is only i the XML layout of the activity
I found this in another question and I don't understand how to implement it into my code.
Your edit text
EditText your_edit_text = (EditText) findViewById(R.id.your_id);
Get user data from edit text as fallows ..
String edit_text_data = your_edit_text.getText().toString();
Now when you need to put that data on url .. use this like ..
String your_url = "http://www.google.com=" + edit_text_data;
I want the Url here in this String in the "" quotations
public static final String UPLOAD_URL =
"https://www.smartpractice.co.za/files-upload-ruben.asp?MyForm=Yes";
UploadActivity JAVA
public class UploadActivity extends AppCompatActivity implements View.OnClickListener {
public static final String UPLOAD_URL = "https://www.smartpractice.co.za/files-upload-ruben.asp?MyForm=Yes";
public static final String UPLOAD_KEY = "image";

public class LoginActivity extends AppCompatActivity {

In short Take editText values from LoginActivity and pass it to UploadActivity and use that information to build a URL in UploadActivity.

Take edittext values from LoginActivity & Pass the values to UploadActivity
Bind your views in onCreate method in LoginActivity (change the ids with yours) & pass the input to UploadActivity through Intent.

{
#Override
public void onClick(View v)
{
String emailAddress = email.getText().toString().trim();
String userPassword = password.getText().toString().trim();
//Pass the data to next activity
String clientId = clientID.getText().toString().trim();
Intent intent = new Intent(LoginActivity.this, UploadActivity.class);
intent.putExtra("clientId", clientId);
intent.putExtra("email", emailAddress);
intent.putExtra("password", userPassword);
startActivity(intent);
}

I am unable to get logic on how do i suppose to give command to print that generated PDF to printer

You'll need to connect to your printer and then send the PDDocument to the connected printer to print it. Something along the following lines should work.
public static PrintService choosePrinter() {
PrinterJob printJob = PrinterJob.getPrinterJob();
if(printJob.printDialog()) {
return printJob.getPrintService();
}
else {
return null;
}
}
public static void printPDF(String fileName, PrintService printer)
throws IOException, PrinterException {
PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintService(printer);
PDDocument doc = PDDocument.load(fileName);
doc.silentPrint(job);
}

How to Using uri get image in RecyclerView?

I'm working on an app in the Android studio. Click the button in the Fragment to open a dialog box and include a picture and a brief description. (Pictures are taken from your gallery.) Click OK to close the dialog box and include the image and description in the RecyclerView that exists in the Fragment. But this code that I've woven has a description, but it doesn's image. I wanted to hear a solution to this, so I asked you a question.
I'd appreciate your reply!
To briefly explain how my code works, when I receive an image from the dialog box, I send the path (/storage/emulated/0/Pictures/a.jpg) of the file as a toast message, and as soon as the dialog is closed, the imagepath and description are transferred to the String form, and the imagepath is converted from Fragment to uri and changed to Bitmap using it to apply to RecyclerView.
Below is my code.
Fragment.java
btn_addlist = view.findViewById(R.id.btn_addlist);
btn_addlist.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment_cus dialog = new DialogFragment_cus();
dialog.show(getActivity().getSupportFragmentManager(), "tag");
dialog.setDialogResult(new DialogFragment_cus.OnMyDialogResult() {
// result : uri, result2 : dlg_edtName, result3 : dlg_edtSubtitle
#Override
public void finish(String result, String result2, String result3) {
imageUri = result; RecyclerInputName = result2;
RecyclerInputSubtitle = result3;
Uri uri = Uri.parse("file://" + imageUri);
Bitmap bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), uri);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
RecyclerItem_cus item = new RecyclerItem_cus(bitmap, RecyclerInputName, RecyclerInputSubtitle);
mArrayList.add(0, item);
mAdapter.notifyDataSetChanged();
Toast.makeText(getActivity(), "finish.", Toast.LENGTH_SHORT).show();
}
});
}
});
DialogFragment.java
dlg_AddButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_PICK);
startActivityForResult(intent, 1);
}
});
dlg_ok.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment_cus fragment = new DialogFragment_cus();
String input1 = dlg_edtName.getText().toString();
String input2 = dlg_edtSubtitle.getText().toString();
if(fragment != null) {
if(mDialogResult != null ) {
mDialogResult.finish(name_Str, input1, input2);
}
}
dismiss();
}
});
dlg_cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dismiss();
}
});
return view;
}
public void setDialogResult(OnMyDialogResult dialogResult){
mDialogResult = dialogResult;
}
public interface OnMyDialogResult{
void finish(String result, String result2, String result3);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1 && resultCode == RESULT_OK) {
try {
name_Str = getImageNameToUri(data.getData());
InputStream in = getActivity().getContentResolver().openInputStream(data.getData());
Bitmap img = BitmapFactory.decodeStream(in);
in.close();
dlg_ImageView.setImageBitmap(img);
dlg_ImageView.setBackgroundResource(android.R.color.white);
Toast.makeText(getActivity(), "name_Str : "+name_Str , Toast.LENGTH_LONG).show();
} catch (Exception e) {
e.printStackTrace();
}
}
}
public String getImageNameToUri(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getActivity().getContentResolver().query(uri, projection, null, null, null);
getActivity().startManagingCursor(cursor);
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(columnIndex);
}
RecyclerView_cusAdapter.java
#Override
public void onBindViewHolder(#NonNull final MyViewHolder myViewHolder, int i) {
final RecyclerItem_cus item = items.get(i);
if (item != null) {
Glide.with(context)
.load(item.getImage())
.asBitmap()
.format(DecodeFormat.PREFER_ARGB_8888)
.into(new SimpleTarget<Bitmap>() {
#Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
myViewHolder.cus_img.setImageBitmap(resource);
}
});
myViewHolder.cus_title.setText(item.getTitle());
myViewHolder.cus_subtitle.setText(item.getSubTitle());
}
}
#Override
public int getItemCount() {
return this.items.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView cus_title;
TextView cus_subtitle;
ImageView cus_img;
public MyViewHolder(View itemView) {
super(itemView);
cus_title = itemView.findViewById(R.id.cus_title);
cus_subtitle = itemView.findViewById(R.id.cus_subtitle);
cus_img = itemView.findViewById(R.id.cus_img);
}
}
RecyclerItem_cus.java
public class RecyclerItem_cus {
private Bitmap image;
private String title;
private String subTitle;
public RecyclerItem_cus(Bitmap image, String title, String subTitle) {
this.image = image;
this.title = title;
this.subTitle = subTitle;
}
public Bitmap getImage() {
return image;
}
public String getTitle() {
return title;
}
public String getSubTitle() {
return subTitle;
}

You can try to use Glide with the File object directly :
Glide.with(mContext)
.load(new File(item.getImage())) // Uri of the picture
.into(myViewHolder.cus_img);

I want to save data in SecondActivity from FirstActivity using Room

I have three activities, I capture all data but one from DetailActivity upon button click and save in database using Room; My intention is to insert all these data into the database and start ReviewActivity so as to get the arraylist of reviews and also insert it in the database. Everything seems to work fine until when I want to view review offline because I believe it has been saved, reviews does not get loaded.
This is my DetailActivity,

Data gets loaded from MainActivity, the saved data is passed on to other activities as a parcellable bundle via intent, the passed data is displayed in DetailActivity but not in ReviewActivity.
Alternatively, if I can load reviews alongside YouTube keys from DetailActivity, I believe I can handle the database issue from there, but two Loaders wouldn't just work together, the app crashes; I am aware two AsyncTasks concurrently run together solved this problem, but I prefer to use Loaders because of performance on configuration change

Parcelable ArrayList is always empty

I want to pass ArrayList via Intent to another activity. However, the code doesn't give any errors but List is always empty. Any idea what i'm doing wrong ? ty
Activity1
private ArrayList<ResimBean> rbList = new ArrayList<ResimBean>();
Bitmap bmp = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] thumbArray = stream.toByteArray();
Uri selectedImageUri = data.getData();
String fotopath = getRealPathFromURI(selectedImageUri);
ResimBean rb = new ResimBean(Parcel.obtain());
// rb.setResim(bar);
rb.setThumbnail(thumbArray);
rb.setPath(fotopath);
rbList.add(rb);
Intent intent = new Intent(getApplicationContext(), ResimListActivity.class);
intent.putParcelableArrayListExtra("reslist",rbList);
startActivityForResult(intent, 100);
Activity2
Bundle extras = getIntent().getExtras();
if (extras != null) {
try {
Intent i = getIntent();
ArrayList<ResimBean> rbList = i.getParcelableArrayListExtra("reslist");
} catch (Exception ex) {
String msg = ex.getMessage();
}
}
Its not giving any error but list is always empty.
EDIT
Added the code how i fill in list.
EDIT 2
Something wrong with my Parcelable class or what ?
public class ResimBean implements Parcelable {
private int Id;
private int HataBildirimId;
private byte[] Resim;
private byte[] Thumbnail;
public byte[] getThumbnail() {
return Thumbnail;
}
public void setThumbnail(byte[] thumbnail) {
Thumbnail = thumbnail;
}
private String Path;
public String getPath() {
return Path;
}
public void setPath(String path) {
Path = path;
}
public int getHataBildirimId() {
return HataBildirimId;
}
public void setHataBildirimId(int hataBildirimId) {
HataBildirimId = hataBildirimId;
}
public int getId() {
return Id;
}
public void setId(int id) {
Id = id;
}
public byte[] getResim() {
return Resim;
}
public void setResim(byte[] resim) {
Resim = resim;
}
#Override
public int describeContents() {
return 0;
}
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(HataBildirimId);
dest.writeByteArray(Resim);
dest.writeByteArray(Thumbnail);
}
public ResimBean(Parcel in) {
readFromParcel(in);
}
public void readFromParcel(Parcel in){
this.HataBildirimId = in.readInt();
this.Resim = new byte[in.readInt()];
this.Thumbnail = new byte[in.readInt()];
}
public static final Parcelable.Creator<ResimBean> CREATOR = new Parcelable.Creator<ResimBean>() {
#Override
public ResimBean createFromParcel(Parcel in) {
return new ResimBean(in);
}
#Override
public ResimBean[] newArray(int size) {
return new ResimBean[size];
}
};

The way you are showing, you create a new ArrayList<> and send it empty as extra via intent to the next activity.
Where exactly do you populate your ArrayList?
You should do something like this:
private ArrayList<ResimBean> rbList = new ArrayList<ResimBean>();
//populate rbList using adapter, then call intent
Intent intent = new Intent(getApplicationContext(), ResimListActivity.class);
intent.putParcelableArrayListExtra("reslist",rbList);
startActivityForResult(intent, 100);
Otherwise, the rbList you send as extra will always be empty. It sounds obvious but I don't know how you are doing it, so this is my best guess.

You can follow this tutorial:
http://aryo.lecture.ub.ac.id/android-passing-arraylist-of-object-within-an-intent/
I got it working like this
Bundle extras = this.getIntent().getExtras();
if (extras != null) {
try {
Intent i = getIntent();
ArrayList<ResimBean> rbList = (ArrayList<ResimBean>) i.getExtras().get("reslist");
Log.i("mytag", " "+i.getExtras().get("reslist").toString());
Log.i("mytag", " "+rbList.get(0).toString());
} catch (Exception ex) {
String msg = ex.getMessage();
}
}
With the rbList in Activity2 size=1,
With your code I was getting size=0
