I am making a project in which i want to select multiple photos from gallery and want to save that in imageview array. I am able to import single image and save at imageview Can anyone tell please how may i import multiple images and save in array or different imageviews?

MainActivity extends Activity implements OnClickListener {

    Button addphoto, save;
    ImageView img1[];
    Bitmap yourbitmap, resized;
    int RESULT_LOAD_IMAGE1 =1;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        addphoto = (Button)findViewById(R.id.add);
        img1[0] = (ImageView)findViewById(R.id.imageView1);
        save = (Button)findViewById(R.id.save);
        addphoto.setOnClickListener(this);
        save.setOnClickListener(this);
    }
@Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        switch(arg0.getId()){
        case R.id.add:
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent, "Select Picture"), RESULT_LOAD_IMAGE1);
            break;
            }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RESULT_LOAD_IMAGE1 && resultCode == RESULT_OK
                && null != data) {
            Uri selectedImage = data.getData();
            String[] filePathColumn = { MediaStore.Images.Media.DATA };

            Cursor cursor = getContentResolver().query(selectedImage,
                    filePathColumn, null, null, null);
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String picturePath = cursor.getString(columnIndex);
            cursor.close();

            try {
                yourbitmap = BitmapFactory.decodeFile(picturePath);
                resized=    Bitmap.createScaledBitmap(yourbitmap, 200,300, true);


                img1[0].setImageBitmap(resized);
            } catch (Exception e) {
                e.printStackTrace();
            }

        }



    }

Complete Working Answer

Intent

Intent intent = new Intent();
intent.setType("image/*");
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
                intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
}
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_MULTIPLE);

Activity Result

    @Override

You can use Uri of images to store their location in MainActivity.java

ArrayList<Uri> Images = new ArrayList<>();
...
...


public void PickImagesIntent(){
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGES);
}

   
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == PICK_IMAGES) {
            if (data.getClipData() != null) {
                ClipData mClipData = data.getClipData();
                for (int i = 0; i < mClipData.getItemCount(); i++) {
                    ClipData.Item item = mClipData.getItemAt(i);
                    Uri imageUri = item.getUri();
                    Images.add(imageUri);
                }
            } else if (data.getData() != null) {
                Uri imageUri = data.getData();
                Images.add(uri);
            }
        }
    }
}

You can send it to another class(ViewImage.java) in form of string

Intent ImageIntent = new Intent(this,ViewImage.class);
ImageIntent.putExtra("imageUri",Images.get(i).toString());
stratActivity(ImageIntent);

To receive it in another class(ViewImage.java)

Intent intent = getIntent();
String imageUriString = intent.getStringExtra("imageUri");
Uri uri = Uri.parse(imageUriSrting);

To set it to ImageView

ImageView imageView = (ImageView)findViewById(##id##);
imageView.setImageURI(uri);

Here is the code for Select Multiple Image and video from Default Gallery.

Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
    buttonLoadImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            Intent i = new Intent();
            i.setType("image/*");
       //i.setType("video/*");
            i.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
            i.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(
                    Intent.createChooser(i, "android.intent.action.SEND_MULTIPLE"), 1);
        }
    });

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    System.out.println("++data" + data.getClipData().getItemCount());// Get count of image here.

        System.out.println("++count" + data.getClipData().getItemCount());
        Uri selectedImage = data.getClipData().getItemAt(0).getUri();//As of now use static position 0 use as per itemcount.
        Bitmap bitmap = null;
  //        Uri selectedImage1 = data.getData();
        try {
            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("+++ clipdate" + selectedImage);

        ImageView imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(bitmap);
    //        }

This is manifest file code for app to get consider you are sending images to your app

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.appshare"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                 <action
                android:name="android.intent.action.SEND_MULTIPLE" />
                 <action
                android:name="android.intent.action.SEND" />
            <category
                android:name="android.intent.category.DEFAULT" />
            <data
                android:mimeType="image/*" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Program code...

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Log.d("MainActivity", "on Create ");

        if (Intent.ACTION_SEND_MULTIPLE.equals(getIntent().getAction())&& getIntent().hasExtra(Intent.EXTRA_STREAM))
        {
                ArrayList<Parcelable> list =
                        getIntent().getParcelableArrayListExtra(Intent.EXTRA_STREAM);
                            for (Parcelable parcel : list) {
                               Uri uri1 = (Uri) parcel;
                               Log.d("MainActivity", "on Create uri1 " + uri1);
                               String sourcepath=getPath(uri1);
                               Log.d("MainActivity", "on Create sourcepath " + sourcepath);
                               /// do things here with each image source path.
                           }
                            //Commented by Aishwary coz I want to open the app after selecting images otherwise uncomment to just select 
                            //finish();
            }else{
                // This part is of single image by Aishwary
                Uri imageUri =(Uri) getIntent().getExtras().get(Intent.EXTRA_STREAM);
                Log.d("MainActivity", "on Create ImageUri " + imageUri);
            }
            }

    public  String getPath(Uri uri) {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(uri, projection, null, null, null);
        startManagingCursor(cursor);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
        }

    }

This will allow you to get source path and images url . Now you can make array for url and use this url as you want...
