我正在开发一个应用程序,因为我使用json调用服务。在那里,无论是什么字符串数据,我使用textView显示它。但我想显示字节数组中的图像。下面是我的代码:
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 {
}
}
});
}
}
我没有得到如何做到这一点。我从这样的服务器获取数据:
{"Comp_Name":null,"DegreeName":"B.E\/B.Tech","EVENT_DATE":null,"Event_LOC":null,"Event_Time":null,"Event_Title":null,"Event_id":null,"HET_UID":null,

答案 0 :(得分:1)
将您的字节数组Image
从json解析为字节数组变量。
将您的字节数组转换为位图,如下所示
Bitmap bmap = BitmapFactory.decodeByteArray(image, 0, image.length); // image is your byte array
将位图bmap设置为ImageView
imageView.setImageBitmap(bmap);
<强>更新强>
试试这个:
一个。像这样得到你的字节数组
JsonArray arr = json.getJSONArray("Image");
湾创建具有Json数组arr
byte[] imageArr = new byte[arr.length()];
℃。迭代将元素插入字节数组
for(int i = 0; i < arr.length(); i++){
imageArr[i] = arr.getInt(i);
}
然后按照步骤1和2来实现目标。
