Android 如何从imageview获取全尺寸图像

我从mobile的摄像头中拍摄了一张2592x1936的图像，并将其转换成位图。我把它显示在我的imageview中，显示为

myImageVew.setImageBitmap（myBitmap）

显示此位图后，我对该图像（在imageview中）执行了一些操作，现在我使用

Bitmap bitmap;
// frmCaptureThis is the root framelayout (this contains my imageview)
View v1 = frmCaptureThis; 
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

saveImgToSDcard(bitmap);

这是将我的图像保存到SD卡，但不是使用
2592x1936
分辨率，而是使用与imageView大小相同的大小（即400X620）保存我的图像。我想以原始分辨率保存图像，即
2592x1936

这是我通过intent拍摄图像的代码

// ////////// Capture Button Handler//////////////////
    btnCapture.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.TITLE, "New Picture");
            values.put(MediaStore.Images.Media.DESCRIPTION,
                    "From your Camera");

            imageUri = getActivity().getContentResolver().insert(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_SCREEN_ORIENTATION,
                    ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            startActivityForResult(intent, REQUEST_OPEN_CAMERA);

        }
    });

这是我关于活动结果的方法

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);

    String imageurl = null;
    if (requestCode == REQUEST_OPEN_CAMERA
            && resultCode == Activity.RESULT_OK) {

        captureFlage = true;
        relTapToCapture.setEnabled(false);
        relHeader.setVisibility(View.INVISIBLE);
        frmCaptureThis.setVisibility(View.VISIBLE);
        btnCapture.setVisibility(View.VISIBLE);
        btnSave.setVisibility(View.VISIBLE);
        txtTapToCapture.setVisibility(View.INVISIBLE);

        try {
            thumbnail = MediaStore.Images.Media.getBitmap(getActivity()
                    .getContentResolver(), imageUri);
        } catch (FileNotFoundException e) {

        } catch (IOException e) {

        }

        imageurl = getRealPathFromURI(imageUri);

        if (thumbnail.getWidth() > thumbnail.getHeight()) {
            // Log.i("Orientation", "LandScape");

            // thumbnail = rotateImage_90(thumbnail);
            imgCaptured.setImageBitmap(thumbnail);

        } else {
            // Log.i("Orientation", "Portrait");
            imgCaptured.setImageBitmap(thumbnail);
        }

        File file = new File(imageurl);
        boolean deleted = file.delete();

    }
    super.onActivityResult(requestCode, resultCode, data);

}

这是我在SD卡中保存图像的方法

public void saveImgToSDcard(Bitmap bitmap) {

    Calendar cal = Calendar.getInstance();
    System.out.println("Current milliseconds since 13 Oct, 2008 are :"
            + cal.getTimeInMillis());

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);

    File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "brandYourImage" + cal.getTimeInMillis()
            + ".jpg");
    try {
        f.createNewFile();
    } catch (IOException e) {

    }
    // write the bytes in file
    FileOutputStream fo = null;
    try {
        fo = new FileOutputStream(f);
    } catch (FileNotFoundException e) {

    }
    try {
        fo.write(bytes.toByteArray());
    } catch (IOException e) {

    }

    // remember close de FileOutput
    try {
        fo.close();
        Toast.makeText(getActivity(), "Saved Successfully",
                Toast.LENGTH_SHORT).show();
    } catch (IOException e) {

    }

}

2592x1936从手机的摄像头中，添加从摄像头获取图像并保存到SD卡的代码。我有代码，但现在没有。我明天就贴。它在我的办公室电脑里：）谢谢。如果你认为你知道答案，你应该给这个问题加上星号。@EmilAdz请查看我的更新代码。很抱歉我的代码粘贴晚了。@QadirHussain嗨。。。你的问题解决了吗？
