imageview

I need to open an image in full screen upon click in the ImageView, like a gallery with one image! How would I do that? Jorgesys this is a basic example: the layout activity_main.xml <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center"> <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustViewBounds="true" android:src="@drawable/ic_launcher"/> </LinearLayout> onCreate() method: private boolean zoomOut =

I want above type of image view in android. Please suggest me better solutions for implement this. Royston Pinto I use the below code to achieve this effect public Bitmap applyReflection(Drawable drawable) { Bitmap originalImage = ((BitmapDrawable)drawable).getBitmap(); final int reflectionGap = 4; int width = originalImage.getWidth(); int height = originalImage.getHeight(); Matrix matrix = new Matrix(); matrix.preScale(1, -1); Bitmap reflectionImage = Bitmap.createBitmap(originalImage, 0, height/2, width, height/2, matrix, false); Bitmap bitmapWithReflection = Bitmap.createBitmap(width,

I need to rotate an ImageView by a few degrees. I'm doing this by subclassing ImageView and overloading onDraw() @Override protected void onDraw(Canvas canvas) { canvas.save(); canvas.scale(0.92f,0.92f); canvas.translate(14, 0); canvas.rotate(1,0,0); super.onDraw(canvas); canvas.restore(); } The problem is that the image that results shows a bunch of jaggies. http://img.skitch.com/20100608-gmdy4sexsm1c71di9rgiktdjhu.png How can I antialias an ImageView that I need to rotate in order to eliminate jaggies? Is there a better way to do this? If you know that your Drawable is a BitmapDrawable, you

Many of us must have come across apps like Tinder and Dripper where you can pull down on the view containing an image and the image zooms in. And then when you let it go, the image zooms out to go back to its origin state. Let's take an example from Tinder : Original State: and Zoomed-in state when pulled: In iOS it is done by - (void)viewDidLoad { [super viewDidLoad]; self.imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"church-welcome.png"]]; self.imageView.contentMode = UIViewContentModeScaleAspectFill; self.cachedImageViewSize = self.imageView.frame; [self.tableView

For example, in my Activity I have such code (I skip the initialization of variables): ImageView iview; //some ImageView Bitmap b; //some Bitmap iview.setImageBitmap(b); Question is - how to clear iview resources correctly (with or without destroying view) ? Would ImageView free it's resources (used in native code) after b.recycle() ? I suppose, that ImageView doesn't just free it resources after Activity onStop (or onDestroy ). imgview.setImageResource(0); or imgview.setImageDrawable(null); no you need to unbindDrawables, you can do it by setting iview.setImageDrawable(null); Dhiraj Singh You

I want to change the brightness on certain part of an image. I know how to use ColorMatrix to change the brightness(or hue) of an image. But it will be applied to the whole image. I have a mask file (black and white image). I want to apply the brightness change only on the the white part of that mask.How to do this in Android? Below is a mask image and the result I want to get. for given bitmap and mask: first create a temporary bitmap: bitmap = BitmapFactory.decodeResource(ctx.getResources(), R.drawable.bitmap); mask = BitmapFactory.decodeResource(ctx.getResources(), R.drawable.mask); float[]

I know there are lots of link available to make ImageView Round Corner. But I'm Using Picasso Library for Image Loading.. I refer the link to get result. But the Problem is that I'm Using it in ListView and for the LIstView's first item ImageView its working perfectly fine but for the remaining once transformation is not working. I am using this transformation: https://gist.github.com/julianshen/5829333 Picasso.with(activity).load(url).transform(new CircleTransform()).into(imageView); You can use RoundedCornersTransformation class of picasso-transformations library. Example : final int radius

I tried to get Bitmap attached to an ImageView, using ImageView.getDrawingCache(); But I found that the returned Bitmap was not the same as I'd like to get from the ImageView. It was always smaller than the real image. I had known that, the method getDrawingCache() should not have the view if it is bigger than the screen as the visible portion of the view is only drawn and the cache holds only what is drawn. Could I get the whole bitmap attached to a ImageView? If you just want the Bitmap from a ImageView the following code may work for you:- Bitmap bm=((BitmapDrawable)imageView.getDrawable())
