How do I save image in imageview?

Question

My app lets you pick an image from gallery and shows it in imageview, but when you close the activity and open it again the image is not there anymore.

  private final static int RESULT_LOAD_IMAGE = 1;

public void getpic(View view) {
    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 selectedimage = cursor.getString(columnIndex);
        cursor.close();

        ImageView imageView = (ImageView) findViewById(R.id.imageButton3);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        imageView.setImageBitmap(BitmapFactory.decodeFile(selectedimage));

    }


}

How can I save the picked image?

you can store image path in shared preference and next time you open app.check if imagePath is there in shared pref then show image — karanatwal.github.io, Jan 09 '17 at 14:17

You can get Bitmap from ImageView to save it:

imageview.buildDrawingCache();
Bitmap bm=imageview.getDrawingCache();

OutputStream fOut = null;
Uri outputFileUri;
try {
    File root = new File(Environment.getExternalStorageDirectory()
        + File.separator + "folder_name" + File.separator);
    root.mkdirs();
    File sdImageMainDirectory = new File(root, "myPicName.jpg");
    outputFileUri = Uri.fromFile(sdImageMainDirectory);
    fOut = new FileOutputStream(sdImageMainDirectory);
} catch (Exception e) {
    Toast.makeText(this, "Error occured. Please try again later.",
    Toast.LENGTH_SHORT).show();
}
try {
    bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
    fOut.flush();
    fOut.close();
} catch (Exception e) {
}

I could not make it work. Please can you show me how you do you access the file after you save it? – Bozhidar Jan 09 '17 at 15:40
Have you provided permission: `` . It 's in you External Storage folder called `folder_name`. – RoShan Shan Jan 09 '17 at 15:42

Use Glide for loading image

add below dependencies in build.gradle(app)

compile 'com.github.bumptech.glide:glide:4.2.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.2.0'

add below code inside your onActivityResult

  Glide
  .with(mContext)
  .load(selectedimage)
  .centerCrop()
  .placeholder(R.color.black)
  .crossFade()
  .into(imageView);

For more details refer https://github.com/bumptech/glide

Glide load local image by Uri.
