android – How to load an image in image view from gallery?

Posted by: admin May 14, 2020 Leave a comment

Questions:

I have an activity, which has a button. When I click on the button it redirects me to the image gallery. I want to show the selected image in the next activity using an image view. But it is not displaying the image. The view is off screen when the image is set.

My code for selecting image and moving on next is given below. I am using no history true in my activities.

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

     if (requestCode == RESULT_LOAD_IMAGE && 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();
        if (!(picturePath.equals(""))) {
            Intent intent = new Intent();
            intent.setClass(MainActivity.this, ImageInGellary.class);
            intent.putExtra("picturePath", picturePath);
            startActivity(intent);

        }
    }
}

public class ImageInGellary extends Activity {
    Button cancel;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.load_image);
        cancel = (Button) findViewById(R.id.buttonCancelPicture);
        Intent in = getIntent();
        savedInstanceState = in.getExtras();
        String picturePath = savedInstanceState.getString("picturePath");
        ImageView imageView = (ImageView) findViewById(R.id.img_view);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
        cancel.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {

                /*
                 * Intent i = new Intent(Intent.ACTION_PICK,
                 * android.provider.MediaStore
                 * .Images.Media.EXTERNAL_CONTENT_URI);
                 * 
                 * startActivityForResult(i, RESULT_LOAD_IMAGE);
                 */
                Intent intent = new Intent();
                intent.setClass(ImageInGellary.this, MainActivity.class);
                startActivity(intent);

            }
        });
    }

}

                cursor.close();

                ImageView imageView = (ImageView) findViewById(R.id.imgView);

            }


        }
    }

Answer:

If you want to achieve it in 1 line then all you need to do is :

Picasso.with(MainActivity.this).load(data.getData()).noPlaceholder().centerCrop().fit().into((ImageView) findViewById(R.id.imageView1));

Complete Solution :-

Pick Image

public void pickImage() {

    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);

}

Load Image

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

            //Get ImageURi and load with help of picasso
            //Uri selectedImageURI = data.getData();

            Picasso.with(MainActivity1.this).load(data.getData()).noPlaceholder().centerCrop().fit()
                    .into((ImageView) findViewById(R.id.imageView1));
        }

    }
}

In your situation you need to pass ImageURI to next activity

Uri selectedImageURI = data.getData();

Answer:

public void onClick(View view) {
    Intent gallery = new Intent(Intent.ACTION_GET_CONTENT);
    gallery.setType("image/*");
    startActivityForResult(gallery, RESULT_LOAD_IMAGE);
}


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

    if(requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK){
        Uri imageUri = data.getData();
        imgView.setImageURI(imageUri);

    }
}

Answer:

If nothing works, the following code will work:

import java.io.FileDescriptor;
import java.io.IOException;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.os.Bundle;
import android.os.ParcelFileDescriptor;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class ImageGalleryDemoActivity extends Activity {


    private static int RESULT_LOAD_IMAGE = 1;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

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

            @Override
            public void onClick(View arg0) {

                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
            }
        });
    }


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

        if (requestCode == RESULT_LOAD_IMAGE && 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();

            ImageView imageView = (ImageView) findViewById(R.id.imgView);

            Bitmap bmp = null;
            try {
                bmp = getBitmapFromUri(selectedImage);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            imageView.setImageBitmap(bmp);

        }


    }



    private Bitmap getBitmapFromUri(Uri uri) throws IOException {
        ParcelFileDescriptor parcelFileDescriptor =
                getContentResolver().openFileDescriptor(uri, "r");
        FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
        Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
        parcelFileDescriptor.close();
        return image;
    }

}

Answer:

I have solved your problem. After the image is picked, convert the image Uri to String and on your second class, convert your string back to image.
