Android firing onTouch event for multiple ImageViews

蓝咒 提交于 2019-11-28 06:12:42
问题 I have several ImageViews, and I want the onTouch event to fire for each of them when I drag my finger across multiple images. At present the onTouch event is only firing on the first ImageView (or actually on multiple ImageViews but only when multitouching the screen). Pseudo code: for(int i=0;i<5;i++){ ImageView img=new ImageView(this); LinearLayout.LayoutParams layoutParams=new LinearLayout.LayoutParams(width,height); img.setImageResource(R.drawable.cell); img.setOnTouchListener(this);

android programmatically blur imageview drawable

一曲冷凌霜 提交于 2019-11-28 06:04:48
I want to programmatically blur and unblur images in Android. I hear that android flag "blur" is no longer supported after API 14 , but I wanted to use Java methods anyway. My main problem is manipulating the bitmap from an Imageview drawable. How would I get the bitmap from an imageview and manipulate it (will probably use gaussian blur) and set it back to the imageview? I think the process involves extracting the drawable, converting the drawable to a bitmap, doing my blur method on that bitmap and then doing the reverse till it is set to the imageview again but I would like that process

How to get the height and width of an ImageView/Bitmap in Android

落花浮王杯 提交于 2019-11-28 04:59:56
I want to get the height and width of an image bitmap that is either in ImageView or a background image. Please help me, any help will be appreciated. Pratik You can get height and width of ImageView by using getWidth() and getHeight() through while this will not give you the exact width and height of the image, for getting the Image width height first you need to get the drawable as background then convert drawable to BitmapDrawable to get the image as Bitmap from that you can get the width and height like here Bitmap b = ((BitmapDrawable)imageView.getBackground()).getBitmap(); int w = b

Android: Bitmap size exceeds 32 bit in DialogFragment

余生颓废 提交于 2019-11-28 04:23:55
问题 This is not a duplicate of Mysterious stacktrace in Android developer console (bitmap size exceeds 32bits) That question didn't provide a single line of code and there's no answer either; besides, I get this error even if I set the Bitmap size to 32x32, it is the only Bitmap, so it is not memory related. What I want to do Get the size of an ImageView, create a BitMap and draw something on a Canvas. The Log.e output for the size of the ImageView and therefore Bitmap is: Width: 272 Height: 136

external allocation too large for this process

问题 I posted a question last night about this issue, but I dont think I explained it well enough to get the proper help. So basically, I have an application where you can press a button which will let you select an image from your gallery and show it in an ImageView I have displayed in the app. This all works great. However, when I press the button again and choose a different picture the app force closes. UPDATE Now, if I take a photo from my downloads photo folder in the gallery it works fine,
