核心代碼如下:

    mLocalRender.setVisibility(View.GONE);
    mRemoteRender.setVisibility(View.GONE);
    mLocalRenderLayout.removeView(mLocalRender);
    mRemoteRenderLayout.removeView(mRemoteRender);
    mLocalRender.setZOrderMediaOverlay(mLocalPreview);
    mRemoteRender.setZOrderMediaOverlay(!mLocalPreview);
    mLocalRenderLayout.addView(mLocalRender, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    mRemoteRenderLayout.addView(mRemoteRender, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    mLocalRender.setVisibility(View.VISIBLE);
    mRemoteRender.setVisibility(View.VISIBLE);
