How to display image taken from camera2 into ImageView preview
0
My Question is very straightforward, I want to display my image in my imageView when I take a picture using the camera 2 API. Below my ImageView and my java code. So far it works but, I wont to display an image inside the ImageView.
<ImageView
android:id="@+id/capturedImageHolder"
android:layout_width="300dp"
android:layout_height="200dp"
Now here is my code, I believe I have to do something here, if I am wrong please correct me.
ImageReader.OnImageAvailableListener readerListener = new ImageReader.OnImageAvailableListener() {
@Override
public void onImageAvailable(ImageReader imageReader) {
Image image = null;
try{
image = reader.acquireLatestImage();
ByteBuffer buffer = image.getPlanes()[0].getBuffer();
byte bytes = new byte[buffer.capacity()];
buffer.get(bytes);
save(bytes);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
}
finally {
{
if(image != null)
image.close();
}
}
}
private void save(byte bytes) throws IOException {
OutputStream outputStream = null;
try{
outputStream = new FileOutputStream(imageFilePath);
outputStream.write(bytes);
}finally {
if(outputStream != null)
outputStream.close();
}
}
};
