我下载了一个Android camera2 demo,它运行良好.

我的代码是

private void setUpCameraOutputs(int width, int height) {

Activity activity = getActivity();

CameraManager manager = (CameraManager) activity.getSystemService(Context.CAMERA_SERVICE);

try {

for (String cameraId : manager.getCameraIdList()) {

CameraCharacteristics characteristics

= manager.getCameraCharacteristics(cameraId);

float[] intrinsic = new float[5];

intrinsic = characteristics.get(CameraCharacteristics.LENS_INTRINSIC_CALIBRATION);

//...... leave out the following part

}

}

内在函数应为5元素数组,但内在= Characteristics.get(CameraCharacteristics.LENS_INTRINSIC_CALIBRATION)返回null.
