I have tested and it’s done I think you are getting Bitmap So you have to convert Bitmap to BitmapDrawable like BitmapDrawable ob = new BitmapDrawable(getResources(), bitmap) then just set bitmap with below function imageView.setBackground(ob); by this way you can do it..
Use ExifInterface for rotate image. Use this method for get correct value to be rotate captured image from camera. public int getCameraPhotoOrientation(Context context, Uri imageUri, String imagePath){ int rotate = 0; try { context.getContentResolver().notifyChange(imageUri, null); File imageFile = new File(imagePath); ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath()); int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL); switch (orientation) { case ExifInterface.ORIENTATION_ROTATE_270: … Read more
This is an old question that has already been accepted, but the following solution may help someone else: If you check res/values/attrs.xml in Android source code, you’ll see the definition of visibility property like this: <!– Controls the initial visibility of the view. –> <attr name=”visibility”> <!– Visible on screen; the default value. –> <enum … Read more
happydude’s answer is the most elegant way to handle this but unfortunately (as pointed out in the comments) the source code for ImageView only accepts an integer (solid colour). Issue 18220 has been around for a couple years addressing this, I’ve posted a workaround there that I’ll summarize here: Extend ImageView and wrap drawableStateChanged() with … Read more
You have to set adjustViewBounds to true. imageView.setAdjustViewBounds(true);
The issue is that adjustViewBounds will not increase the size of the ImageView beyond the natural dimensions of the drawable. It will only shrink the view to maintain aspect ratio; if you provide a 500×500 image instead of a 50×50 image, this should work. If you’re interested in the spot where this behavior is implemented, … Read more
centre of the imageView will be centreX=imageView.getX() + imageView.getWidth() / 2; centreY=imageView.getY() + imageView.getHeight() / 2; but make sure you call it after the imageView created
If you’re in API 21+ you can do this easily in XML with a selector and tint: <?xml version=”1.0″ encoding=”utf-8″?> <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:state_activated=”true”> <bitmap android:src=”https://stackoverflow.com/questions/19500039/@drawable/ic_settings_grey” android:tint=”@color/primary” /> </item> <item android:drawable=”https://stackoverflow.com/questions/19500039/@drawable/ic_settings_grey”/> </selector>
Alright, I had a quick play with this and noticed your issue of the circles disappearing. Without you describing what exactly you tried, I assume you haven’t tried setting the color filter to the Drawable itself yet? (as opposed to the ImageView, which only seems to work with BitmapDrawables). The following statements work perfectly fine … Read more
This is how you can convert a Bitmap to a ByteArray and a ByteArray to a Bitmap: Convert Bitmap to ByteArray: Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); ByteArrayOutputStream stream = new ByteArrayOutputStream(); bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); byte[] byteArray = stream.toByteArray(); Convert ByteArray to Bitmap: Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length); ImageView image = (ImageView) findViewById(R.id.imageView1); image.setImageBitmap(Bitmap.createScaledBitmap(bmp, image.getWidth(), … Read more
