Im trying to do image slider with gallery images.I can get image from gallery but I could not to display like a slideshow , Could you help me about that how can I do that.

basically I am creating an app where users can upload his/her files on drive by creating folders. Here I have been Successfully created a folder now the issue wt I am facing is how to upload files on that folder which the user just created.where the user can select multiple images, videos, docs, etc. For the select purpose, I have chosen intent but am not able to get how to upload it. Here's the code wt I have done till now.
For Creating Folder I used this method now I want to upload files in this folder please let me know
if (mDriveServiceHelper == null) {
return;
}
mDriveServiceHelper.createFolder("FolderNew", null)
.addOnSuccessListener(new OnSuccessListener<GoogleDriveFileHolder>() {

Gson gson = new Gson();
Log.d(TAG, "onSuccess: " + gson.toJson(googleDriveFileHolder));
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.d(TAG, "onFailure: " + e.getMessage());
}
});

I need to store the path of selected image from gallery. In the Toast i am getting the String
imageEncoded =null. I also have a List variable imageEncodedList which also gives 'null' in the Toast
when multiple images are selected. What i am doing wrong? i want to store the path of selected images in android. Also what i need to do for API level <18 for selecting images from gallery?
int SELECT_PICTURES=1;
String imageEncoded;
List<String> imagesEncodedList;
select_image.setOnClickListener(new View.OnClickListener() {

Add Permission in manifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
For getClipData
if (data.getClipData() != null) {
ClipData mClipData = data.getClipData();
ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
for (int i = 0; i < mClipData.getItemCount(); i++) {
ClipData.Item item = mClipData.getItemAt(i);
Uri uri = item.getUri();
mArrayUri.add(uri);
Toast.makeText(this, "" + getImageFilePath(uri), Toast.LENGTH_SHORT).show();
}
}
For Image Path:
public String getImageFilePath(Uri uri) {
File file = new File(uri.getPath());
String[] filePath = file.getPath().split(":");
String image_id = filePath[filePath.length - 1];
Cursor cursor = getContentResolver().query(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, null, MediaStore.Images.Media._ID + " = ? ", new String[]{image_id}, null);
if (cursor != null) {
cursor.moveToFirst();
String imagePath = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
cursor.close();
return imagePath;
}
return null;
}
I have an app which contain a "imageview" and a "button" known as uploadImage. when i click uploadimage it is opening a a chooser option from where user can choose image and set it in imageview. Problem is that before setting image in image view i want to check whether image size is not more that 200 kb if found then show toast message otheriwse proceed further.
code:-
private void showFileChooser() {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent,PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
// Set the Image in ImageView after decoding the String
m_UploadImage.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
You can check the image size using the following Code:
Bitmap bitImage = BitmapFactory.decodeResource(getResources(),
R.drawable.ic_launcher);// For example I took ic_launcher
Bitmap bitmap = bitImage;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] imageInByte = stream.toByteArray();
long sizeOfImage = imageInByte.length; //Image size
Your Code :
private void showFileChooser() {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent,PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
// Set the Image in ImageView after decoding the String
Bitmap bitImage = BitmapFactory.decodeFile(imgDecodableString);
Bitmap bitmap = bitImage;
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] imageInByte = stream.toByteArray();
long sizeOfImage = imageInByte.length; //Image size
//Code to check image size greater than 20KB
if(sizeofImage/1024 > 200){
Toast.makeText(this, "Image size more than 200KB", Toast.LENGTH_LONG)
}else{
m_UploadImage.setImageBitmap(bitImage);
}
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
Or you can try this way ,
First you get the Bitmap attached on the ImageView:
using this :
Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();
In your code :
private void showFileChooser() {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent,PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
// When an Image is picked
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
// Get the cursor
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
// Set the Image in ImageView after decoding the String
m_UploadImage.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
//Get the Bitmap in your ImageView
Bitmap bitmap = ((BitmapDrawable)m_UploadImage.getDrawable()).getBitmap();
// Then check the Image size
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] imageInByte = stream.toByteArray();
long lengthbmp = imageInByte.length;
Toast.makeText(this, "Length of the Image :" + lengthbmp,
Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
Better you create a an another class and write this public method in that class because in future you can use this class.
public class UtilClassName{
public static int getFileSize(Uri imageUri,Activity activity){
int kb_size=0;
try {
InputStream is=activity.getContentResolver().openInputStream(imageUri);
int byte_size=is.available();
int kb_size=byte_size/1024;
}
catch (Exception e){
// here you can handle exception here
}
return kb_size;
}
}
In your code use this logic
if(UtilClassName.getFileSize(selectedImage,this)<=200){
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
// Set the Image in ImageView after decoding the String
m_UploadImage.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
}
else{
//show a warning to the user
}
Try this method and if you are facing any issue let me know. I had faced this problem before and i created this method for a file compressor class. I hope you will get solution.
I want to open gallery with multiple image selection functionality and i am using following code.
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);
It opens gallery app but doesn't let me choose multiple images.
This worked for me from api22 to api29.
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setData(MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, 105);
then in activity result overmethod add this code.
if (resultCode == RESULT_OK && requestCode == 105) {
ClipData clipData = data.getClipData();
if (clipData != null) {
for (int i = 0; i < clipData.getItemCount(); i++) {
Uri imageUri = clipData.getItemAt(i).getUri();
// your code for multiple image selection
}
} else {
Uri uri = data.getData();
// your codefor single image selection
}
Note: after you got the gallery screen hold the image little longer. then in top right click "open". it will allow you to select multiple images.
To select multiple images I use this :
Declare a variable
ActivityResultLauncher activityResultLauncher;
2.Call Register Method in OnCreate Method
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.upload_ad_images);
RegisterOpenImageDialog();
}
3.this is the register method
private void RegisterOpenImageDialog() {
activityResultLauncher = registerForActivityResult(new ActivityResultContracts.GetMultipleContents(), new ActivityResultCallback<List<Uri>>() {
#Override
public void onActivityResult(List<Uri> result) {
if (result != null) {
int x = result.size();
//Do What you Want Here ................
}
}
});
}
4.when the user click select image button
private void btnSelectImage() {
activityResultLauncher.launch("image/*");
}
Click and hold to select multiple image. Don't just click on image. Also you can receive those image using this.
int PICK_IMAGE_MULTIPLE = 1;
String imageEncoded;
List<String> imagesEncodedList;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
// When an Image is picked
if (requestCode == 1 && resultCode == RESULT_OK
&& null != data) {
// Get the Image from data
String[] filePathColumn = { MediaStore.Images.Media.DATA };
imagesEncodedList = new ArrayList<String>();
if(data.getData()!=null){
Uri mImageUri=data.getData();
// Get the cursor
Cursor cursor = getContentResolver().query(mImageUri,
filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imageEncoded = cursor.getString(columnIndex);
cursor.close();
}else {
if (data.getClipData() != null) {
ClipData mClipData = data.getClipData();
ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
for (int i = 0; i < mClipData.getItemCount(); i++) {
ClipData.Item item = mClipData.getItemAt(i);
Uri uri = item.getUri();
mArrayUri.add(uri);
// Get the cursor
Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
// Move to first row
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imageEncoded = cursor.getString(columnIndex);
imagesEncodedList.add(imageEncoded);
cursor.close();
}
Log.v("LOG_TAG", "Selected Images" + mArrayUri.size());
}
}
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)

if (cursor.moveToFirst()) {

res = cursor.getString(column_index);
}
cursor.close();
return res;
}
#Override
public void onClick(View v) {
openImageChooser();
}
}
Add Permission in manifest file.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
I have an onclick that will allow a user to select a file from gallery like so:
case R.id.ColourCustom:
customBorderChange();
break;
private void customBorderChange() {
final ImageView QPBackground = (ImageView) findViewById(R.id.QPBackground);
menuHandler.removeCallbacks(menuTimer);
menuHandler.postDelayed(menuTimer, 5000);
bgHandler.removeCallbacks(runnableBG);
bgHandler.postDelayed(runnableBG, 2000);
Intent i = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, GALLERY_REQUEST);
File file = getFileStreamPath("QuickPlayBG.png");
if (file.exists()) {
QPBackground.setImageBitmap(getThumbnail("QuickPlayBG.png"));
} else {
String uri21 = "#drawable/bg_green";
int imageResource21 = getResources().getIdentifier(uri21, null, getPackageName());
QPBackground.setBackgroundResource(imageResource21);
}
}
This sends you here:
protected void onActivityResult (int requestCode, int resultCode, Intent data)
{
Uri selectedImageUri;
if (requestCode == GALLERY_REQUEST && resultCode == RESULT_OK && null !=
data) {
selectedImageUri = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImageUri,
filePathColumn, null, null, null);
cursor.moveToFirst();
cursor.close();
}
try {
Bundle extras = data.getExtras();
Bitmap photo = extras.getParcelable("data");
saveBGFile(photo);
} catch (Exception e) {
String errorMessage = "Make your mind up mate!";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
try {
saveQPConfig();
} catch (IOException e) {
String errorMessage = "Saving failed";
Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
toast.show();
}
}
Which saves the file, using saveBGFile:
public void saveBGFile(Bitmap image) {
FileOutputStream out = null;
String filename = "QuickPlayBG.png";
try {
out = new FileOutputStream(filename);
image.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
The issue is with this line only:
QPBackground.setImageBitmap(getThumbnail("QuickPlayBG.png"));
It doesn't load anything. If I change "QuickPlayBG.png" to another filename that I am using in another part of my app, it loads fine. Both files are created using the same method. I verified that "QuickPlayBG.png" exists.
Compiler gives me the following hint:
E/﹕ ReadStreamToBuffer : Qmage Stream read error!! required length 12 bytes, but red 0 bytes
E/﹕ isQmage : input SkStreamRewindable length is less than Qmage minimum size : 0
I think it has to do with the way I am saving the image, but I cannot see the fault myself. What could be the problem, that it is not loading the image?
Edit:
Here is the getThumbnail method I am using (works for another filename):
public Bitmap getThumbnail(String filename) {
final Context context = this;
String fullPath = Environment.getExternalStorageDirectory().getAbsolutePath();
Bitmap thumbnail = null;
if (thumbnail == null) {
try {
File filePath = context.getFileStreamPath(filename);
FileInputStream fi = new FileInputStream(filePath);
thumbnail = BitmapFactory.decodeStream(fi);
} catch (Exception ex) {
Log.e("getThumbnail() !exist", ex.getMessage());
}
}
return thumbnail;
}
Use this short and sweet code for this. use intent of gallery.
1.declaire variable.
private static int RESULT_IMG = 1;
String imgString;
2.call intent of gallery on onclick of button.
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
3.onActivityResult to your code.
#Override
protected void onActivityResult(int requestCode, int responseCode, Intent data) {
super.onActivityResult(requestCode, responseCode, data);
try {
if (requestCode == RESULT_IMG && responseCode == RESULT_OK
&& null != data) {
Uri pickedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(pickedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgString = cursor.getString(columnIndex);
cursor.close();
//set bitmap to your imageview
ImageView imgView = (ImageView) findViewById(R.id.imgView);
imgView.setImageBitmap(BitmapFactory.decodeFile(imgString));
} else {
Toast.makeText(this, "please select picture",Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "error message", Toast.LENGTH_LONG)
.show();
}
}
