Description

Check if the camera is sideways without taking a picture, but we'll take an educated guess based on whether the camera's preview sizes are mostly the same as our current orientation.

Demo Code


//package com.java2s;

import android.app.Activity;

import android.hardware.Camera;

import android.view.Display;

import java.util.List;

public class Main {
    public static boolean getIsCameraSideways(
            List<Camera.Size> cameraPreviewSizes, Activity activity) {
        // Get screen dimensions
        Display display = activity.getWindowManager().getDefaultDisplay();
        int width = display.getWidth();
        int height = display.getHeight();

        boolean isPortrait = (height >= width);
        int numSidewaysOrientations = 0;

        for (Camera.Size size : cameraPreviewSizes) {
            if (isPortrait == (size.height <= size.width)) {
                numSidewaysOrientations++;
            }//from   w w w .jav a2  s  . co  m
        }

        return (numSidewaysOrientations > cameraPreviewSizes.size() / 2);
    }
}
