以下代码用于将项目从tileview控件拖放到树列表控件。它使用devexpress控件。

但是在放下该项目之后,被拖动的项目的预览像下面的图像一样在窗口上停留,并且直到鼠标光标悬停它时它才会隐藏。 有隐藏的方法吗?

enter image description here

OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();   
OkHttpClient okHttpClient = clientBuilder.build();
MultipartBody.Builder builder = new MultipartBody
        .Builder()
        .setType(MultipartBody.FORM);
for (int i = 0; i < fileList.size(); i++) {
        File file = new File(fileList.get(i));
        builder.addFormDataPart(path, path, 
        RequestBody.create(MediaType.parse("application/octet-stream"), file));
}
RequestBody body = builder.build();
final Request request = new Request.Builder()
        .url(upLoadUrl)
        .post(body)
        .build();
okHttpClient.newCall(request).enqueue(new Callback() {})

在这里,我使用MouseDown和MouseMove事件开始拖放操作
