三星的Galaxy S4图像捕捉问题

问题描述

我开发一个Android应用程序。我创建了一个自定义相机类捕捉图像。这是工作的罚款在索姆许多设备，但是当我试图与三星Galaxy S4返回图像灰度林家，如图所示。我的code是：

 ！[`*公共无效surfaceCreated（SurfaceHolder持有者）{
    frontCam = SharedUser prefs.getShared prefData（AutoCapture.this，
            Constants.IS_FRONT_CAMERA）;

    如果（frontCam.equals（Constants.VALUE_ON））{

        为（中间体camIdx = 0; camIdx＆其中; Camera.getNumberOfCameras（）; camIdx ++）{
            Camera.getCameraInfo（camIdx，cameraInfo）;
            如果（cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT）{
                尝试 {
                    mCamera = Camera.open（camIdx）;
                }赶上（RuntimeException的E）{
                    Log.e（TAG，
                            摄像头无法打​​开：
                                    + e.getLocalizedMessage（））;
                }
            }
        }

    } 其他 {
        mCamera = Camera.open（）;
    }
    mCamera.setDisplayOrientation（90）;
    Camera.Parameters p值= mCamera.getParameters（）;
    如果（getPackageManager（）。hasSystemFeature（
            PackageManager.FEATURE_CAMERA_FLASH））{
        如果（flashOn.equals（Constants.VALUE_ON））{
            {
                p.setFlashMode（Camera.Parameters.FLASH_MODE_TORCH）;
            }
        }
    } 其他 {
        p.setFlashMode（Camera.Parameters.FLASH_MODE_OFF）;
    }
    p.setPictureFormat（ImageFormat.JPEG）;

    名单＆LT; Camera.Size＆GT; previewSizes = p.getSupported previewSizes（）;
    Camera.Size previewsize = previewSizes.get（0）;
    对于（Camera.Size大小：previewSizes）{
        Log.d（宽度---+ size.width，高度---+ size.height）;
    }

    P.SET previewSize（previewsize.width，previewsize.height）;

    mCamera.setParameters（对）;

}

公共无效surfaceChanged（SurfaceHolder持有人，INT格式，INT W，INT高）{
    Log.e（TAG，surfaceChanged）;

    如果（M previewRunning）{
        mCamera.stop preVIEW（）;
    }

    尝试 {
        mCamera.set previewDisplay（保持器）;

    }赶上（IOException异常E）{

        的System.out.println（表面chagned捕获的异常）;
        e.printStackTrace（）;
    }
    mCamera.start preVIEW（）;
    米previewRunning = TRUE;

}

公共无效surfaceDestroyed（SurfaceHolder持有者）{
    Log.e（TAG，surfaceDestroyed）;

    如果（M previewRunning == FALSE）{
        如果（mCamera！= NULL）{
            米previewRunning = FALSE;
            mCamera.stop preVIEW（）;
            mCamera.release（）;
        }
        如果（mCamera！= NULL）{
            米previewRunning = FALSE;
            mCamera.release（）;
        }
    } / *
     *否则，如果（mCamera！= NULL）{M-previewRunning = FALSE;
     * mCamera.stop preVIEW（）; mCamera.release（）; }
     * /

} *`] [2]
 

解决方案

我觉得你有我和这个其他人也做了同样的问题。

Samsung银河S4，图像被同时从相机采取损坏

I am developing an Android Application. I created a custom camera class to capture images. It is working fine in som many devices but when i Tried it with Samsung Galaxy S4 it returns image with gray lins as shown. My Code is :

![`*public void surfaceCreated(SurfaceHolder holder) {
    frontCam = SharedUserPrefs.getSharedPrefData(AutoCapture.this,
            Constants.IS_FRONT_CAMERA);

    if (frontCam.equals(Constants.VALUE_ON)) {

        for (int camIdx = 0; camIdx < Camera.getNumberOfCameras(); camIdx++) {
            Camera.getCameraInfo(camIdx, cameraInfo);
            if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                try {
                    mCamera = Camera.open(camIdx);
                } catch (RuntimeException e) {
                    Log.e(TAG,
                            "Camera failed to open: "
                                    + e.getLocalizedMessage());
                }
            }
        }

    } else {
        mCamera = Camera.open();
    }
    mCamera.setDisplayOrientation(90);
    Camera.Parameters p = mCamera.getParameters();
    if (getPackageManager().hasSystemFeature(
            PackageManager.FEATURE_CAMERA_FLASH)) {
        if (flashOn.equals(Constants.VALUE_ON)) {
            {
                p.setFlashMode(Camera.Parameters.FLASH_MODE_TORCH);
            }
        }
    } else {
        p.setFlashMode(Camera.Parameters.FLASH_MODE_OFF);
    }
    p.setPictureFormat(ImageFormat.JPEG);

    List<Camera.Size> previewSizes = p.getSupportedPreviewSizes();
    Camera.Size previewsize = previewSizes.get(0);
    for (Camera.Size size : previewSizes) {
        Log.d("Width---" + size.width, "Height---" + size.height);
    }

    p.setPreviewSize(previewsize.width, previewsize.height);

    mCamera.setParameters(p);

}

public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
    Log.e(TAG, "surfaceChanged");

    if (mPreviewRunning) {
        mCamera.stopPreview();
    }

    try {
        mCamera.setPreviewDisplay(holder);

    } catch (IOException e) {

        System.out.println("Caught exception in surface chagned");
        e.printStackTrace();
    }
    mCamera.startPreview();
    mPreviewRunning = true;

}

public void surfaceDestroyed(SurfaceHolder holder) {
    Log.e(TAG, "surfaceDestroyed");

    if (mPreviewRunning == false) {
        if (mCamera != null) {
            mPreviewRunning = false;
            mCamera.stopPreview();
            mCamera.release();
        }
        if (mCamera != null) {
            mPreviewRunning = false;
            mCamera.release();
        }
    }/*
     * else if (mCamera != null) { mPreviewRunning = false;
     * mCamera.stopPreview(); mCamera.release(); }
     */

I think you have the same issue me and this other guy did.
