I believe most of you all have seen the rotating FloatingActionButton in apps such as Google keep, push bullet and even Google inbox app. I am trying to achieve this rotation by having an animation file that is : <?xml version="1.0" encoding="UTF-8"?> <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:fromDegrees="0" android:toDegrees="135" android:pivotX="50%" android:pivotY="50%" android:repeatCount="0" android:fillAfter="true" android:fillEnabled="true" android:duration="100" /> Right now I am using makovkastar library to do this FAB button.

I am trying to programically set the background of my app with an image in my drawable-hdpi folder. It is only seeing the default ic_launcher file in R.drawable so when I go to set the background, its simply unexistant. I am using this class as a fragment class with a swipe menu so maybe that has something to do with it.

I am stuck on this seemingly easy issue. What am I doing wrong ? ImageView mImageView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mImageView = (ImageView)findViewById(R.id.control); ClipDrawable drawable = (ClipDrawable)mImageView.getDrawable(); drawable.setLevel(10); } The app crashes at drawable.setLevel(10) with a NullPointerException (drawable is null). Here is my xml: circle.xml <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android

I need to create a pattern to set as a background of some View . I want the pattern to look something like this: I don't want to import any image to drawable, but instead, I want to create my own shapes, layer-list and the ultimate goal is to have a pattern as a background. Is is possible to achieve this without having to import any external image? 0X0nosugar You can get a pattern of repeating tiles based upon shape drawables by creating a custom View and overriding onDraw() . Let's start by creating the tile as a layer list made of shape drawables, in this case alternating squares of black

I know that in Android Studio there are some plugins for including a drawable that help in creating a ldpi, mdpi, hdpi, etc image resource. But suppose I have an app in which some users upload images to a server and then I download the images and display them for other users, how can I adapt them so that they adapt to ldpi, mdpi, hdpi screens? Is there a library that runs on the server or client? Pavneet_Singh there are two ways , either you do it or let other do it you can use picasso (image loading library ) with fit function and just relax . link find the required size and compress the
