pinchzoom

I have a little problem with my app. I have just implemented pinch zoom, but when I pinch to zoom, the image does not scale at the centre of the 2 points as displayed in the images below. Image 1 is where my fingers are before pinching and image 2 is to display that it has not scaled out at the centre of my fingers like it should. Image 1 vs Image 2: Here is my code: package com.jpiionefourone.guitarimage; import android.content.Context; import android.graphics.Canvas; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.view.MotionEvent; import android

I am new to android development, sorry if I ask some stupid question please try to help me. I am trying to implement the Zoom and pinch in RelativeLayout. I want to make my own map view in which I'll get the image of floor map and draw the pins(ImageVIew) on it. I've tried it out but i am currently unable to click on the pins. I've done the code with the help of these posts Extending RelativeLayout, and overriding dispatchDraw() to create a zoomable ViewGroup and Android - zoom in/out RelativeLayout with spread/pinch My Code is public class TempView extends RelativeLayout { private static

In Xamarin , what is the best way to enable pinch zooming for an image? Currently I have just an ImageView that has a Bitmap image as an image. I have done some research, and I have found a few examples where people have used some other libraries but would like some advice on the best way to enable pinch zooming on an image before I start writing this code. So, what is the best way to enable pinch zooming on an image in Android , specifically Xamarin ? Thank in advance You can get ImageView zoom-in capabilities and panning of the zoomed in image by using the Monodroidtoolkit ScaleImageView.

For my question I have prepared a very simple test app at Github. For simplicity I have removed flinging, scroll constraints and edge effects (which actually work well in my real app): So the custom view in my test app only supports scrolling: mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() { @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float dX, float dY) { mBoardScrollX -= dX; mBoardScrollY -= dY; ViewCompat.postInvalidateOnAnimation(MyView.this); return true; } }); and pinch zooming with 2 fingers (the focus is broken though

I am using chrisbanes PhotoView to implement pinch zoom..Image zooms on pinching and double tapping but i can't see that my image streched to full screen on zooming..on zooming it looks that image zooms inside a box and part of image disappears on zooming...How can i implement image zoom so that height of Image increases on zooming?I am using NetworkImageView ( of Volley library). NetworkImageView imageView; PhotoViewAttacher mAttacher; imageView = (NetworkImageView) mImgPagerView.findViewById(R.id.imageitem); mAttacher = new PhotoViewAttacher(imageView); NetworkImageView.java ( of Volley

I am using code found in Hello Android, 3rd Edition for Pinch to Zoom functionality. After using this the pinch to zoom works fine, but after zooming i want to get the absolute click position on the image view. Here is my code package org.example.touch; import android.app.Activity; import android.graphics.Bitmap; import android.graphics.Matrix; import android.graphics.PointF; import android.os.Bundle; import android.util.FloatMath; import android.util.Log; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.widget.GridView; import

My app has to display a number of high resolution images (about 1900*2200 px), support pinch zoom. To avoid Out of memory error I plan to decode image to show full screen by using options.inSampleSize = scale (scale was calculated as Power of 2 as Document) (My view i used is TouchImageView extends of ImageView ) So i can quickly load image and swipe smoothly between screens(images). However, when i pinch zoom, my app loses detail because of scaled image. If i load full image, i can't load quickly or smoothly swipe, drag after pinch zoom. Then i try to only load full image when user begin

I have an EditText I want to zoom it, and scroll with setScaleX / setScaleY and it works fine - text is being edited in the right position. But when I try to select text - it draws selection handles to positions like when text is not scaled. It is known bug . It's expected result because handles are drawn on popup window related to view size. All actions on android.widget.Editor are targeted to its field private TextView mTextView; . And if we will set own editor by reflection, I don't know what to do with private methods, that are no overridable. Also selection handles are drawn on Popup

I have an application in which I need to implement image editing, which also includes pinch zooming. I am done with pinch zooming but I can test this only on device, not on emulator. Is there any way for testing pinch zooming in android emulator, any shortcut key or any other way? K_Anas Since ADT 17, it is possible to use a physical Android 4.0 device to send multitouch gestures to the emulator. See Android's instructions here . Multi-Touch The emulator supports multi-touch input, as an experimental feature in r17, using a tethered Android device running the SdkControllerMultitouch
