Java 如何在Parse.com中存储和接收配置文件图片?
我是parse.com的新手。我已经搜索了几个小时如何为用户创建一张个人资料图片,但没有结果。我知道如何上传图片到Parse.com,但我不知道如何接收它 这是我上传图像的方式:Java 如何在Parse.com中存储和接收配置文件图片?,java,android,parsing,parse-platform,Java,Android,Parsing,Parse Platform,我是parse.com的新手。我已经搜索了几个小时如何为用户创建一张个人资料图片,但没有结果。我知道如何上传图片到Parse.com,但我不知道如何接收它 这是我上传图像的方式: // Save new user data into Parse.com Data Storage ParseUser user = new ParseUser(); user.setUsername(usernametxt);
// Save new user data into Parse.com Data Storage
ParseUser user = new ParseUser();
user.setUsername(usernametxt);
user.setPassword(passwordtxt);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Compress image to lower quality scale 1 - 100
photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] image = stream.toByteArray();
// Create the ParseFile
ParseFile file = new ParseFile(usernametxt + ".png", image);
// Upload the image into Parse Cloud
file.saveInBackground();
// Create a New Class called "ImageUpload" in Parse
ParseObject imgupload = new ParseObject("ImageUpload");
// Create a column named "ImageName" and set the string
imgupload.put("ImageName", usernametxt);
// Create a column named "ImageFile" and insert the image
imgupload.put("ImageFile", file);
// Create the class and the columns
imgupload.saveInBackground();
// Show a simple toast message
Toast.makeText(RegisterActivity.this, "Image Uploaded",
Toast.LENGTH_SHORT).show();
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Show a simple Toast message upon successful registration
Intent intent = new Intent(
RegisterActivity.this,
Welcome.class);
startActivity(intent);
finish();
} else {
Toast.makeText(getApplicationContext(),
"Sign up Error", Toast.LENGTH_LONG)
.show();
}
}
});
}
}
这就是我接收图像的方式(不工作,导致异常):
ParseQuery=ParseQuery.getQuery(“ImageUpload”);
query.whereEqualTo(“ImageName”,currentUser.getUsername());
getFirstInBackground(新的GetCallback(){
如果有人会看看代码,并试图给我一个线索,我做错了,这将非常有帮助我
对不起,我的英语很差。保存到Parse-只需调用ParseUser表而不是ParseObject表
Bitmap bitmapImage = ((BitmapDrawable) profilepic.getDrawable()).getBitmap(); // profile pic is the imageview
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmapImage.compress(Bitmap.CompressFormat.JPEG, 40, stream);
byte[] byteArray = stream.toByteArray();
ParseFile file = new ParseFile("image.png", byteArray);
ParseObject Images = new ParseObject("Images");
Images.put("profilepic", file);
Images.put("username", Username);
Images.saveInBackground(new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
Log.i("AppInfo", "Profile pic success");
} else {
Log.i("AppInfo", "Profile pic FAIL");
}
}
});
从解析中检索
ParseQuery<ParseUser> imageQuery = new ParseUser.getQuery();
imageQuery.whereEqualTo("objectId",ParseUser.getCurrentUser().getObjectId());
imageQuery.findInBackground(new FindCallback<ParseObject>()
{
@Override
public void done(List<ParseUser> users,ParseException e)
{
for(ParseUser user : users)
{
ParseFile UserProPicFile = object.getParseFile("ImageColumnName");
byte[] byteArray = new byte[0];
byteArray = UserProPicFile.getData();
Bitmap ProselectBit = BitmapFactory.decodeByteArray(byteArray,0,byteArray.length); //Bitmap with [rofile picture
}
}
});
ParseQuery imageQuery=new ParseUser.getQuery();
imageQuery.whereEqualTo(“objectId”,ParseUser.getCurrentUser().getObjectId());
findInBackground(新的FindCallback()
{
@凌驾
public void done(列出用户,parsee异常)
{
for(解析用户:用户)
{
ParseFile UserProPicFile=object.getParseFile(“ImageColumnName”);
byte[]byteArray=新字节[0];
byteArray=UserProPicFile.getData();
位图ProselectBit=BitmapFactory.decodeByteArray(byteArray,0,byteArray.length);//带有[rofile picture]的位图
}
}
});
我希望这有帮助
ParseQuery<ParseUser> imageQuery = new ParseUser.getQuery();
imageQuery.whereEqualTo("objectId",ParseUser.getCurrentUser().getObjectId());
imageQuery.findInBackground(new FindCallback<ParseObject>()
{
@Override
public void done(List<ParseUser> users,ParseException e)
{
for(ParseUser user : users)
{
ParseFile UserProPicFile = object.getParseFile("ImageColumnName");
byte[] byteArray = new byte[0];
byteArray = UserProPicFile.getData();
Bitmap ProselectBit = BitmapFactory.decodeByteArray(byteArray,0,byteArray.length); //Bitmap with [rofile picture
}
}
});
