There is no built-in scale type that allows the ImageView to automatically upscale the image and keep its aspect ratio intact. The only scale type that does upscaling is fitXY, which won’t respect the aspect ratio, as you found out yourself too. That being said, this topic has already been visited more than once. Have … Read more
Update: For newer version please checkout the Glide Samples (https://github.com/bumptech/glide/tree/master/samples/svg) – You can use Glide (https://github.com/bumptech/glide/tree/v3.6.0) and AndroidSVG (https://bitbucket.org/paullebeau/androidsvg). There is also a sample from Glide: https://github.com/bumptech/glide/tree/v3.6.0/samples/svg/src/main/java/com/bumptech/svgsample/app Setup GenericRequestBuilder requestBuilder = Glide.with(mActivity) .using(Glide.buildStreamModelLoader(Uri.class, mActivity), InputStream.class) .from(Uri.class) .as(SVG.class) .transcode(new SvgDrawableTranscoder(), PictureDrawable.class) .sourceEncoder(new StreamEncoder()) .cacheDecoder(new FileToStreamDecoder<SVG>(new SvgDecoder())) .decoder(new SvgDecoder()) .placeholder(R.drawable.ic_facebook) .error(R.drawable.ic_web) .animate(android.R.anim.fade_in) .listener(new SvgSoftwareLayerSetter<Uri>()); Use RequestBuilder with … Read more
You can create a resource (layer drawable xml) for your ImageView‘s “border” (actually background), and declare in your theme that the ImageView‘s background resource is the drawable xml. If you need this “border” to be changed based on the ImageView‘s state (focused, selected, etc.), then you should create more layer drawables, and put them together … Read more
It is not clear exactly what you are trying to do. If you are talking about JavaFX 2.0, the following code works. If you are loading a lot of images and need to conserve memory, you only have to create enough ImageView’s for the number you want to display at one time. Then as you … Read more
This one sample makes ImageView’s transparent area not clickable. ImageView: ImageView imgView= (ImageView) findViewById(R.id.color_blue); imgView.setDrawingCacheEnabled(true); imgView.setOnTouchListener(changeColorListener); OnTouchListener: private final OnTouchListener changeColorListener = new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { Bitmap bmp = Bitmap.createBitmap(v.getDrawingCache()); int color = bmp.getPixel((int) event.getX(), (int) event.getY()); if (color == Color.TRANSPARENT) return false; else { //code to execute … Read more
If you want to use FXML, you should separate the controller (like you were doing with the SampleController). Then your fx:controller in your FXML should point to that. Probably you are missing the initialize method in your controller, which is part of the Initializable interface. This method is called after the FXML is loaded, so … Read more
<RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”fill_parent” android:layout_height=”fill_parent” android:background=”@color/white” > <ImageView android:id=”@+id/inside_imageview” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:layout_marginBottom=”5dip” android:layout_marginTop=”5dip” android:src=”https://stackoverflow.com/questions/11959841/@drawable/frame” /> <ImageView android:id=”@+id/outside_imageview” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:layout_alignTop=”@id/inside_imageview” android:layout_alignBottom=”@id/inside_imageview” android:layout_alignLeft=”@id/inside_imageview” android:layout_alignRight=”@id/inside_imageview” android:scaleType=”fitXY” /> </RelativeLayout> The layout_align[Top|Bottom|Left|Right] attribute in RelativeLayout is used to align views based on their respective x and y values within the margin. The second ImageView will now be aligned to the … Read more
I had the same challenge and came to the conclusion that overwriting onDraw will at least in the general case not work. My blog explains the reasons. What worked very well for me is the following: Create a new image bitmap and attach a brand new canvas to it. Draw the image bitmap into the … Read more
There is no difference between the two internally setImageBitmap is calling setImageDrawable. Below code is picked from ImageView.java of AOSP public void setImageBitmap(Bitmap bm) { // if this is used frequently, may handle bitmaps explicitly // to reduce the intermediate drawable object setImageDrawable(new BitmapDrawable(mContext.getResources(), bm)); }
You can use ImageView below two properties to show image based on your requirement : android:adjustViewBounds : Set this to true if you want the ImageView to adjust its bounds to preserve the aspect ratio of its drawable. android:scaleType :Controls how the image should be resized or moved to match the size of this ImageView … Read more
