android - Imageview dosn't update -


I want to change the image view 3 times in a short time. I want to set this image, Sheldon "Boxing" Say, change the image directly after the audio is complete. And then I want to do this for the second time. Note that the first image is already set before calling this function: 

  sound = MediaPlayer.create (this, R.raw.bazinga); Sound.start (); Page.setImageResource (R.drawable.counttotwofirst); While (sound.isPlaying ()) {} sound.start (); Page.setImageResource (R.drawable.counttotwosecond); While (sound.isPlaying ()) {} sound.release (); Page.setClickable (true);

I have invalid (); Tried to use , but he could not work.

Is anybody forced to update or at least the image view has been updated? If updates in image views take time? What other footage should I use instead?

Think again that the design is a little bit. I'm guessing that you're running that code on your app's main (UI) thread. The problem is that although you are changing image processing, then you are blocking the UI thread (for a while) in the loop, so the UI updates are not displayed until after your full function returns. Some more pieces are needed to get the sound / animation effect. Create a background thread to run sound loading / playback, possibly from top of my head so that on the UI thread In addition, instead of sitting in the loop for some time () until the sound is over, it would be better to inform the callback that playback has completed (take a look at MediaPlayer :: setOnCompletionListener).

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
