copied!<p><strong>Answer:</strong></p> <p>1) Start with the source code of the GLSurfaceView, name the file GLTextureView.java</p> <p>2) Change the header to: <strong>GLTextureView extends TextureView implements SurfaceTextureListener</strong></p> <p>3) Rename constructors to GLTextureView. Remove code from init() method.</p> <p>4) Organize imports. Always choose the non-GLSurfaceView option.</p> <p>5) Find every instance of SurfaceHolder and change it to a SurfaceTexture</p> <p>6) Add Unimplemented methods for the SurfaceTextureListener, each method should be as follows:</p> <ul> <li>onSurfaceTextureAvailable - surfaceCreated(surface)</li> <li>onSurfaceTextureDestroyed - surfaceDestroyed(surface), (return true)</li> <li>onSurfaceTextureSizeChanged - surfaceChanged(surface, 0, width, height)</li> <li>onSurfaceTextureUpdated - requestRender()</li> </ul> <p>7) There should be one line where there is a call being made to getHolder(), change that to getSurfaceTexture()</p> <p>8) In the init() method, put the following line <code>setSurfaceTextureListener(this)</code></p> <p>Then add an <code>OnLayoutChangeListener</code> and have it call <code>surfaceChanged(getSurfaceTexture(), 0, right - left, bottom - top)</code>.</p> <p>With that you should be able to replace your GLSurfaceView code with <code>GLTextureView</code> and receive the benefits of <code>GLTextureView</code>. Also make sure your app supports Hardware Acceleration and that your Renderer extends <code>GLTextureView</code>.Renderer.</p>
