Actually I have no idea how to solve my problem. I captured some data

  • 0

Actually I have no idea how to solve my problem. I captured some data into an array, so the values present there look like that: {-11, -53, -27, 50, 39, ..., ...}. I just want to know, how I can show these values on the screen, in a graph. I have not yet any implementation idea, otherwise I would give some code snippets. Sry for that.

additional information: The data is captured from microphone and I use a method of AudioRecord calss to read into a short array (public int read (short[] audioData, int offsetInShorts, int sizeInShorts)). As AudioRecord read in chunks of data, I want to update the screen while capturing, but that’s for later…

I just want to know, how I can show these values on the screen, in a graph. Which layout, just some point where I can start from. Would be nice if anybody can help me.

Thanks in advance for your help.

    If you don’t need real-time updates, I suggest you to use one of the many chart libraries around. Check my answer here for a list: which is the best and easy way to display stock graph in android?

    If you do need real-time updating, you’ll most probably have to implement a SurfaceView and do your drawing yourself. Check the Lunar Lander example for an implementation of SurfaceView.
