imageview

I had implemented an image view with the zoom and drag functionalities.I am using matrix for the zoom and drag functionality.But my problem is that I cant set my minimum and maximum zoom level and the drag space limit.can any on e tell me how I can do that. private float spacing(MotionEvent event) { float x = event.getX(0) - event.getX(1); float y = event.getY(0) - event.getY(1); return FloatMath.sqrt(x * x + y * y); } private void midPoint(PointF point, MotionEvent event) { float x = event.getX(0) + event.getX(1); float y = event.getY(0) + event.getY(1); point.set(x / 2, y / 2); } private

I want to display external image like: " http://abc.com/image.jpg " in my android phone application. can any one guide me how to achieve this? Francesco Laurita There are many ways to achieve your request. Basically you have to download the image with an urlrequest and then using the InputStream to create a Bitmap object. Just a sample code: URL url = new URL("http://asd.jpg"); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is

I am getting image from an url. I am using imageview in listview. I want to add the list of bitmap images into the each row of the list item. I used SimpleAdapter but the imageview shows blank.My code is below !! ArrayList<HashMap<String, Bitmap>> mylist = new ArrayList<HashMap<String, Bitmap>>(); Bundle bundle = this.getIntent().getExtras(); get = bundle.getString("name"); try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://www.propertyhookup.com/mobile/propertylist.php"); nameValuePairs = new ArrayList<NameValuePair>(1); nameValuePairs.add(new

This is my problem...: In my activity I have an ImageView and a Button . I want the Button to perform an action ONLY when the ImageView displays a certain drawable. And yes, this means that the ImageView is animating between various drawables that is coded such that it does not interrupt with what I want done. ImageView imgview = (ImageView)findViewById(R.id.imgviewsid); Resources res = getResources(); Drawable acertaindrawable = res.getDrawable(R.drawable.thecertaindrawable); Drawable variabledrawable = imgview.getDrawable(); if (variabledrawable == acertaindrawable) { //does something } It

I have one requirement in which i have to zoom in and zoom out images on pinch.. Please if anyone can suggest me pinch zoom functionality for Imageview.???? try this import android.content.Context; import android.graphics.Canvas; import android.graphics.drawable.BitmapDrawable; import android.util.AttributeSet; import android.util.Log; import android.view.MotionEvent; import android.view.ScaleGestureDetector; import android.view.View; public class MyImageView extends View { private static final int INVALID_POINTER_ID = -1; private Drawable mImage; private float mPosX; private float mPosY;

This is the original image: This is the rendered image using ImageView: However, sometimes when the image is in a carousel, swiping back to the image may cause the image to render correctly, which is even more weird... This behavior is observed both on an LG G3 (Android 5.1) and Genymotion (Android 4.4.4). I'm using the Glide library for loading images, using the ARGB_8888 decode format: new GlideBuilder(this).setDecodeFormat(DecodeFormat.PREFER_ARGB_8888); This is a resolved issue 305 . Here is a quick recap: This issue appears only with images with JPEG format (the quality is irrelevant). It
