Hi i have a string in Base64 format. I want to convert it ot a bitmap and then display it to an ImageView. This is the code:
ImageView user_image;
Person person_object;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_profile_screen);
// ImageViews
user_image = (ImageView) findViewById(R.id.userImageProfile);
Bundle data = getIntent().getExtras();
person_object = data.getParcelable("person_object");
// getPhoto() function returns a Base64 String
byte[] decodedString = Base64.decode(person_object.getPhoto(), Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
user_image.setImageBitmap(decodedByte);
}
This code get the Base64 String successfully and i do not get any error. But It does not display the image. What can be the problem? Thanks
Please try this:
byte[] decodedString = Base64.decode(person_object.getPhoto(),Base64.NO_WRAP);
InputStream inputStream = new ByteArrayInputStream(decodedString);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
user_image.setImageBitmap(bitmap);
this code works with me
ImageView carView = (ImageView) v.findViewById(R.id.car_icon);
byte[] decodedString = Base64.decode(picture, Base64.NO_WRAP);
InputStream input=new ByteArrayInputStream(decodedString);
Bitmap ext_pic = BitmapFactory.decodeStream(input);
carView.setImageBitmap(ext_pic);
//decode base64 string to image
imageBytes = Base64.decode(encodedImage, Base64.DEFAULT);
Bitmap decodedImage = BitmapFactory.decodeByteArray(imageBytes, 0, imageBytes.length);
image.setImageBitmap(decodedImage);
//setImageBitmap is imp
There is a library named Picasso which can efficiently load images from a URL. It can also load an image from a file.
Examples:
Load URL into ImageView without generating a bitmap:
Picasso.with(context) // Context
.load("http://abc.imgur.com/gxsg.png") // URL or file
.into(imageView); // An ImageView object to show the loaded image
Load URL into ImageView by generating a bitmap:
Picasso.with(this)
.load(artistImageUrl)
.into(new Target() {
@Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
/* Save the bitmap or do something with it here */
// Set it in the ImageView
theView.setImageBitmap(bitmap)
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
});
There are many more options available in Picasso. Here is the documentation.
