我在parse.com上将5张图片保存到了我的班级.我可以在imageView中基于objectid下载一个图像.我需要将所有5张图像下载到我的5张ImageViews中.我怎样才能做到这一点.任何帮助,将不胜感激.谢谢
ParseQuerySEObject> query = new ParseQuerySEObject>("Footer");
// Locate the objectId from the class
query.getInBackground("tNp607WyQD",new GetCallbackSEObject>() {
public void done(ParSEObject object,ParseException e) {
// TODO Auto-generated method stub
// Locate the column named "ImageName" and set
// the string
ParseFile fileObject = (ParseFile) object.get("imageFile");
fileObject.getDataInBackground(new GetDataCallback() {
public void done(byte[] data,ParseException e) {
if (e == null) {
Log.d("test","We've got data in data.");
// Decode the Byte[] into
// Bitmap
Bitmap bmp = BitmapFactory.decodeByteArray(data,data.length);
// Get the ImageView from main.xml
//ImageView image = (ImageView) findViewById(R.id.ad1);
ImageView ad1=(ImageView) findViewById(R.id.ad1);
// Set the Bitmap into the
// ImageView
ad1.setImageBitmap(bmp);
// Close progress dialog
progressDialog.dismiss();
} else {
Log.d("test","There was a problem downloading the data.");
}
}
});
}
});
}}
最佳答案
我可以在imageloader类的帮助下解决这个问题：
public class Login extends Activity {
public ImageLoader imgl;
EditText fullname,mobilenumber,occupation;
Button save;
ImageView ad1,ad2,ad3,ad4,ad5,ad6;
ListSEObject> ob;
private ImageView[] imgs = new ImageView[5];
ProgressDialog progressDialog;
int i=0;
HorizontalScrollView horizontalScrollView1;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.userdata);
imgl=new ImageLoader(getApplicationContext());
fullname = (EditText) findViewById(R.id.fullname) ;
mobilenumber = (EditText) findViewById(R.id.mobile) ;
occupation = (EditText) findViewById(R.id.occupation) ;
save=(Button) findViewById(R.id.btnSave);
horizontalScrollView1=(HorizontalScrollView) findViewById(R.id.horizontalScrollView1);
ad1=(ImageView) findViewById(R.id.ad1);
ad2=(ImageView) findViewById(R.id.ad2);
ad3=(ImageView) findViewById(R.id.ad3);
ad4=(ImageView) findViewById(R.id.ad4);
ad5=(ImageView) findViewById(R.id.ad5);
ad6=(ImageView) findViewById(R.id.ad6);
imgs[0] = ad2;
imgs[1] = ad3;
imgs[2] = ad4;
imgs[3] = ad5;
imgs[4] = ad6;
progressDialog= ProgressDialog.show(Login.this,"","Downloading Image...",true);
// Locate the class table named "Footer" in Parse.com
ParseQuerySEObject> query = new ParseQuerySEObject>(
"Footer");
query.orderByDescending("updatedAt");
try {
ob = query.find();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (ParSEObject country : ob) {
ParseFile image = (ParseFile) country.get("imageFile");
imgl.DisplayImage(image.getUrl(),imgs[i]);
i=i+1;
System.out.println("the urls are"+image.getUrl());
progressDialog.dismiss();
}
}
}
