how to select from resources randomly (R.drawable.xxxx)

由 删除回忆录丶 提交于 2019-12-03 10:58:38
问题 I want to display a random image from the bunch of images i have stored in res/drawable. The only technique that I know is to access a particular image if you know its resource id. Is there a way to access the images by using the filenames or something else (which can be constructed at runtime)? I want to randomly select an image at runtime. Any suggestions/ideas appreciated :) Thanks Chinmay 回答1: You can also access resources by name, which may be a viable approach to solving your problem if

Android uploading pictures to server in most efficient way

由 China☆狼群 提交于 2019-12-03 09:47:40
问题 I need to get images along with other data (very similar to email with attachements) to the server. I also need to do it in reliable manner so I can retry, etc on failure. Server is WCF REST server and I do lot of other communications with it(JSON) but just got this new requirement to upload images. Since I use JSON to post data to my server - I use GSON on Android side to serialize data. Here is how I got it implemented so far (everything else works this way but I just started with images)

How to save cropped image in android instead of returning cropping data?

由 一个人想着一个人 提交于 2019-12-03 09:13:47
I have an application where I can let the user choose a gallery image or take a picture with camera, then after that I give him the option to crop it. Now when the user crops the image the Gallery cropper returns ByteArray of the cropped part, is it possible to pass a parameter asking the Gallery cropper to save the output to file (Just like the case when I start a intent to capture and image in the camer) e.g.: This is the code of cropping that I Use: // Initialize intent Intent intent = new Intent("com.android.camera.action.CROP"); // set data type to be sent intent.setType("image/*"); //

Android Blur View (Blur background behind the view)

由 一世执手 提交于 2019-12-03 07:38:12
问题 I am trying to make the bottom part of an Image blur for the view on top it like in the image. I tried blurring it using Rendenscript but I am not able to blur only the part behind the view. :( I have seen many libraries but almost all of them blur the entire image, but not a part of it. Also, an important part is that I am using this inside a ViewPager and hence needs to be fast and dynamic something like this in IOS which redraws itself the moment image behind it changes. Any help is

I would like to encode video from sequence of images with java only in my current android project. I mean without any use of external tools such as NDK. Also is there any availability of java libraries for encoding video from sequence of images ? 回答1: You can use a pure java library called JCodec ( http://jcodec.org ). It contains a primitive yet working H.264 ( AVC ) encoder and a

android bitmap isn't created from base64

由 心已入冬 提交于 2019-12-02 17:02:33
问题 I have an Android application which sends an image to a web service. I want to send the same photo back from the web service to Android. I made a test program to compare the base64 data that's sent from Android to the server and the base64 that's sent back from server to Android -- they are exactly equal. I want to use the base 64 string to create a bitmap, so I tried this: String image = client1.getBaseURI("restaurantFoods/OneFood/" + this.getID() + "/getImage"); byte[] decodedString =

Putting some indicator around the image in image move/resize/rotate operations

由 為{幸葍}努か 提交于 2019-12-02 15:35:12
I would like to Scale, Move, Resize Image. I would like to surround the image with Indicators which guide user what operation these indicators perform i.e. Moving, Rotating, Scaling. I've tried Scaling - but it only crops down. No chance to increase length and height of image. Rotate - achieved but via inserting manual degrees. That's not a good option in here. Moving - as I'm achieving drag on Api < 11. So little bit of difficult. Still no hope in here. Is there any library which can do me simple image edit [Move, Scale, Rotate]? You can use Matrix transaformation to achieve rotating, scaling

Animating all items in Animation-list

由 青春壹個敷衍的年華 提交于 2019-12-02 04:12:35
I have a list of images(around 10) in my "image_list.xml" under "animation-list" specified with "item". And I have made one "fade_in.xml" file for fade in effect of the imgaes. The code works fine without errors. The only problem I have is that the fade in effect appears in the first image but not in the other items of the image_list. Please tell me a way to make this possible so that all the images have fade in effect when they appear.My code is: image_list.xml <?xml version="1.0" encoding="utf-8"?> <animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot=
