把Android中setSurface部分的源码发给我

好的，以下是Android中setSurface方法的部分源码：

/**
 * This is called by the WindowManager with the new Surface that is being
 * used to display this window.  For non-embedded applications it will always
 * be the same as the Surface passed to create().
 *
 * @param surface The Surface being used to display this window.
 */
public void onWindowAttributesChanged(WindowManager.LayoutParams attrs) {
    synchronized (mWindowManagerLock) {
        final int fl = attrs.flags;
        if ((fl&WindowManager.LayoutParams.FLAG_SHOW_WALLPAPER) != 0) {
            if (!mShowWallpaper) {
                mShowWallpaper = true;
                if (mLastSurface != null) {
                    try {
                        mSession.setWallpaperPosition(mWindow, mLastSurface.getWidth(),
                                mLastSurface.getHeight(), mLastSurfaceLayer);
                    } catch (RemoteException e) {
                    }
                    updateSurface(false, false);
                }
            }
        } else if ((fl&WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD) != 0) {
            if (!mDismissKeyguardOnNextSurfaceUpdate) {
                mDismissKeyguardOnNextSurfaceUpdate = true;
                updateSurface(false, false);
            }
        } else {
            mShowWallpaper = false;
        }
        if (mSurfaceHolder != null) {
            mSurfaceHolder.setFlags(
                    (attrs.flags&WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON)
                            | (attrs.flags&WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON),
                    WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                            | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        }
    }
}

注意，这里只展示了部分源码，如果您需要完整的源码，建议到Android源码仓库中查看。
