如何在android中使用解析api在解析服务器中上传图像 [英] How to upload an image in parse server using parse api in android

问题描述

我想在 android 中的解析云服务器中上传图像.但我做不到.

我尝试了以下代码:

 Drawable drawable = getResources().getDrawable(R.drawable.profilepic) ;位图 bitmap = (Bitmap)(Bitmap)drawable()ByteArrayOutputStream 流 = new ByteArrayOutputStream();bitmap.compress(Bitmap.CompressFormat.PNG, 100, 流);byte[] data = stream.toByteArray();ParseFile imageFile = new ParseFile("image.png", data);imageFile.saveInBackground();

请告诉我该怎么做.

解决方案

在后台保存 ParseObject

<块引用>

//解析对象ParseObject pObject = new ParseObject("ExampleObject");pObject.put("myNumber", number);pObject.put("myString", name);pObject.saveInBackground();//异步，无回调

使用回调在后台保存

<块引用>

pObject.saveInBackground(new SaveCallback() {@覆盖公共无效完成(解析异常前){if (ex == null) {isSaved = true;} 别的 {//失败的isSaved = false;}}});

save...() 方法的变体包括:

<块引用>

 saveAllinBackground() 保存带有或不带有回调的 ParseObject.saveAll(List objects) 保存 ParseObjects 的列表.saveAllinBackground(List objects) 将 ParseObjects 的列表保存在背景.saveEventually() 允许您在将来的某个时间将数据对象保存到服务器；用如果当前无法访问 Parse 云，则使用此方法.

一旦 ParseObject 成功保存在云上，它就会被分配一个唯一的 Object-ID.这个 Object-ID 非常重要，因为它唯一标识了 ParseObject 实例.例如，您可以使用对象 ID 来确定对象是否已成功保存在云中、检索和刷新给定的 Parse 对象实例以及删除特定的 ParseObject.

我希望你能解决你的问题..

I want to upload an image in parse cloud server in android. But I am unable to do so.

I have tried the following code:

    Drawable drawable = getResources().getDrawable(R.drawable.profilepic) ;
    Bitmap bitmap = (Bitmap)(Bitmap)drawable()
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] data = stream.toByteArray();                

    ParseFile imageFile = new ParseFile("image.png", data);
    imageFile.saveInBackground();

Please let me know how can I do it.

解决方案

Save ParseObject in the background

// ParseObject
  ParseObject pObject = new ParseObject("ExampleObject");
  pObject.put("myNumber", number);
  pObject.put("myString", name);
  pObject.saveInBackground(); // asynchronous, no callback

Save in the background with callback

pObject.saveInBackground(new SaveCallback () {
   @Override
   public void done(ParseException ex) {
    if (ex == null) {
        isSaved = true;
    } else {
        // Failed
        isSaved = false;
    }
  }
});

Variations of the save...() method include the following:

    saveAllinBackground() saves a ParseObject with or without a callback.
    saveAll(List<ParseObject> objects) saves a list of ParseObjects.
    saveAllinBackground(List<ParseObject> objects) saves a list of ParseObjects in the 
    background.
    saveEventually() lets you save a data object to the server at some point in the future; use 
    this method if the Parse cloud is not currently accessible.

Once a ParseObject has been successfully saved on the Cloud, it is assigned a unique Object-ID. This Object-ID is very important as it uniquely identifies that ParseObject instance. You would use the Object-ID, for example, to determine if the object was successfully saved on the cloud, for retrieving and refreshing a given Parse object instance, and for deleting a particular ParseObject.

I hope you will solve your problem..
