如何在Android设备中获取相机传感器尺寸？

谁能知道如何在 Android设备中获取相机的传感器尺寸？

谢谢

解决方法

从API级别21开始是可能的.从文档( https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#SENSOR_INFO_PHYSICAL_SIZE)：

public static final Key SENSOR_INFO_PHYSICAL_SIZE

The physical dimensions of the full pixel array. […]

Units: Millimeters

我用这种代码.请注意,可能不仅仅是一台摄像头：

import android.hardware.camera2.CameraAccessException;
import android.hardware.camera2.Cameracharacteristics;
import android.hardware.camera2.CameraManager;

private Sizef getCameraResolution(int camNum)
{
    Sizef size = new Sizef(0,0);
    CameraManager manager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    try {
        String[] cameraIds = manager.getCameraIdList();
        if (cameraIds.length > camNum) {
            Cameracharacteristics character = manager.getCameracharacteristics(cameraIds[camNum]);
            size = character.get(Cameracharacteristics.SENSOR_INFO_PHYSICAL_SIZE);
        }
    }
    catch (CameraAccessException e)
    {
        Log.e("YourLogString",e.getMessage(),e);
    }
    return size;
}

请注意,需要捕获Exception CameraAccessException.

别忘了添加< uses-sdk android：minSdkVersion =“21”/>到你的清单.
