jsonを使用してバイト配列で画像を印刷する方法

Question

私はアプリケーションを開発しています.jsonを使用してサービスを呼び出しています。そこにある文字列データは、textViewを使って表示しています。私はthat.Iを行う方法を得ていないのです

  t1 = (TextView) findViewById(R.id.t1); 
    i = (ImageView) findViewById(R.id.imageview); 
    String url = "url" 
    AQuery mAQuery = new AQuery(MainActivity.this); 
    mAQuery.ajax(url, String.class, new AjaxCallback<String>() { 
     @Override 
     public void callback(String url, String data, AjaxStatus status) { 
      super.callback(url, data, status); 
      if (android.support.v7.appcompat.BuildConfig.DEBUG) { 
       Log.d("###$Request URL", url + ""); 
       Log.d("###$Response ", data + ""); 
       Log.d("###$Status Message : ", status.getMessage() + ""); 
       Log.d("###$Status Code : ", status.getCode() + ""); 

      } 

      if (status.getCode() != -101) { 

       String StringData = "" + data; 
       try { 


        JSONObject json = new JSONObject(StringData); 
        int sd; 
        sd = json.getInt("Stu_id"); 

        String Name = json.getString("Stu_FName"); 
        String LastName = json.getString("Stu_LName"); 
        String Degree = json.getString("DegreeName"); 


        t1.setText("Details OF STUDENTS"); 
        t1.setText("First Name: " + Name + "\n" + "Last Name:" + LastName + "\n" + "Degree: " + Degree); 

       } catch (JSONException e) { 

       } 
      } else { 

      } 
     } 
    }); 
} 

}

次のようにサーバーからデータを取得しています：しかし、私は私のコードであるバイトarray.Belowにある画像を表示したい

Answer 1

1. バイト配列Imageをjsonからバイト配列変数にパースします。

2. Bitmap bmap = BitmapFactory.decodeByteArray(image, 0, image.length); // image is your byte array 
   

3. はこれを試してみてくださいImageView

   imageView.setImageBitmap(bmap); 
   

更新

にビットマップBMAPを設定して下のようにビットマップに自分のバイト配列に変換：

a。このようなバイト配列を取得する

JsonArray arr = json.getJSONArray("Image"); 

b。 Json配列のサイズを持つバイト配列オブジェクトを作成します。arr

byte[] imageArr = new byte[arr.length()]; 

cです。バイト配列に要素を挿入するために繰り返します。

for(int i = 0; i < arr.length(); i++){ 
    imageArr[i] = arr.getInt(i); 
} 

次に、手順1と2を実行して目的を達成します。
