GLSurfaceViewメモ

GLSurfaceViewのサイズ変更

LayoutParamsでサイズ指定してGLSurfaceView.setLayoutParams()で設定

.java

public class MainActivity extends Activity {

    private GLSurfaceView mGLView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mGLView = new GLSurfaceView(this);
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(800,400);
        mGLView.setLayoutParams(params);
        setContentView(mGLView);
        
        ...

GLSurfaceViewの保存

GLSurfaceView.Rendererの継承クラスに新しくメソッドを作り、その中で別スレッド立てて行う

.java

int pixels[] = new int[width * height];
IntBuffer buffer = IntBuffer.wrap(pixels);
buffer.position(0);

GLES20.glReadPixels(0, 0, width, height, GLES20.GL_RGBA, GLES20.GL_UNSIGNED_BYTE, buffer);

Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
bitmap.copyPixelsFromBuffer(buffer);

try {
    FileOutputStream fos = null;
    fos = new FileOutputStream(new File(DOWNLOAD + "/tmp.png"));
    bmp.compress(Bitmap.CompressFormat.PNG, 100, fos);
    fos.close();
    Log.d("Plug-in", "save: " + DOWNLOAD + "/tmp.png");
}catch (IOException ex) {
    Log.d("Plug-in", ex.toString());
}
