可以在服务器成功响应中获取照片路径并删除!确保在 list 中声明权限!

<uses-permission> android:name="android.permission.WRITE_INTERNAL_STORAGE" />

在你的代码中..

PostResponseAsyncTask task = new PostResponseAsyncTask(MainActivity.this, postData, new AsyncResponse() {


        @Override
        public void processFinish(String s) {


            if (s.contains("uploaded_success")) {
                File photoDelete = new File(selectedPhoto);
                if (photoDelete.exists()) {
                    if (photoDelete.delete()) {
                        Log.d("DELETE", "deleted:" + selectedPhoto);
                    }
                }
                Toast.makeText(getApplicationContext(), "Image Uploaded Successfully", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getApplicationContext(), "Error while uploading...", Toast.LENGTH_SHORT).show();
            }

        }
    });
