确定的Andr​​oid设备上的相机高度和宽度 [英] Determine Android Device's Camera Height and Width

问题描述

我努力想在一个解决方案，应用程序的屏幕尺寸将是灵活的设备不同的屏幕尺寸。我想获得该设备的摄像头的高度和宽度。有，我们可以在Java中，获取设备的摄像机的高度和宽度，并返回值将被分配给变量CAMERA_WIDTH和CAMERA_HEIGHT调用一个函数？或任何方式做到这一点？除了与实数分配它。谢谢！

I was trying to think over of a solution that an application's screen size will be flexible on different screen sizes of devices. I thought of getting the device's camera height and width. Is there a function that we can call in Java that gets the device's camera's height and width and the returned values will be assigned to the variables CAMERA_WIDTH and CAMERA_HEIGHT? or any ways to do it? aside from assigning it with real numbers. THANK YOU!

推荐答案

这是一个方法：

Camera.Parameters params = mCamera.getParameters(); // mCamera is a Camera object
List<Camera.Size> sizes = params.getSupportedPreviewSizes();

// position: variable where you choose between different supported resolutions, 
// this varies from phone to phone, even the order can be different, 
// ex. ascending or descending order.

mFrameWidth = (int) sizes.get(position).width;
mFrameHeight = (int) sizes.get(position).height;

params.setPreviewSize(mFrameWidth, mFrameHeight);
mCamera.setParameters(params);
