Android GLSurfaceView在屏幕旋转后绘图区域异常的解决办法

添加代码

public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);

DisplayMetrics mDisplayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(mDisplayMetrics);
int W = mDisplayMetrics.widthPixels;
int H = mDisplayMetrics.heightPixels;

if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
imageSurfaceView.getLayoutParams().width = W;
imageSurfaceView.getLayoutParams().height = H;

}
else{
imageSurfaceView.getLayoutParams().width = W;
imageSurfaceView.getLayoutParams().height = H;
}
}
