android camera2 设置,如何设置android camera2预览和捕获大小？

我使用SurfaceView来显示我捕获的预览.我想使用width = 1080,height = 1920进行预览.我在哪里可以设置预览的大小？

我用谷歌搜索了一个答案,但它们都是用于相机版本的.我使用的是android.hardware.camera2.

private void takePreview() {

try {

final CaptureRequest.Builder previewRequestBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);

previewRequestBuilder.addTarget(mSurfaceHolder.getSurface());

mCameraDevice.createCaptureSession(Arrays.asList(mSurfaceHolder.getSurface(), mImageReader.getSurface()), new CameraCaptureSession.StateCallback() // ③

{

@Override

public void onConfigured(CameraCaptureSession cameraCaptureSession) {

if (null == mCameraDevice) return;

mCameraCaptureSession = cameraCaptureSession;

try {

previewRequestBuilder.set(CaptureRequest.CONTROL_AF_MODE, CaptureRequest.CONTROL_AF_MODE_CONTINUOUS_PICTU
