如何从其他活动获取图像路径

Question

我应该怎样做才能获得拍摄图像的拍照。这样我可以在第二个活动中显示它作为drawable？ 第一项活动

    btn_cam.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            file = new File(MainActivity.this.getExternalCacheDir(),
                    String.valueOf(System.currentTimeMillis()) + ".jpg");
            fileUri = Uri.fromFile(file);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
            MainActivity.this.startActivityForResult(intent, CAMERA_PIC_REQUEST);
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent resultData) {
    if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) {
        fileUri = data.getData();
            Intent cam = new Intent(this, MainCam.class);
            cam.putExtra("flostic", fileUri.toString());
            startActivity(cam);
            this.finish();

第二次活动

            String image_path = getIntent().getStringExtra("flostic");

            BitmapFactory.Options options = new BitmapFactory.Options();
            options.inPreferredConfig = Bitmap.Config.ARGB_8888;
            Bitmap bitmap = BitmapFactory.decodeFile(image_path, options);
            view.setImageBitmap(bitmap);
