我正在尝试使用个人资料图片进行signUp活动,但是我收到一条错误消息:无法对未保存的解析文件进行编码。我在另一个类中有相同的代码,它没有任何问题。
我认为问题可能是使用ParseUser而不是ParseObject。请帮帮我,这是我的代码。
public class SignUpActivityStep3 extends ActionBarActivity {
public static final String YOUR_APPLICATION_ID = "kuN8ihs88AYhRR1jIWT9psCGUXxSOveJPqVVsBnq";
public static final String YOUR_CLIENT_KEY = "vC4eA9CqulpgkxJ7sTPtoPSANkMxFeiFlYXwODYK";
byte[] Image;
ParseFile photo = null;
String User, Pass, Email, Description;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signupstep3);
Parse.initialize(this, YOUR_APPLICATION_ID, YOUR_CLIENT_KEY);
EditText Desc = (EditText) findViewById(R.id.txtDesc);
Button Finish = (Button) findViewById(R.id.btnFinish);
Intent intent = getIntent();
User = intent.getStringExtra("User");
Pass = intent.getStringExtra("Pass");
Email = intent.getStringExtra("Email");
Image = intent.getByteArrayExtra("Image");
photo = new ParseFile("userpicture.png", Image);
photo.saveInBackground();
savetoParse();
}
private void savetoParse() {
ParseUser user = new ParseUser();
user.setUsername(User.toString());
user.setPassword(Pass.toString());
user.put("Profile", photo);
user.setEmail(Email.toString());
user.signUpInBackground(new SignUpCallback() {
@Override
public void done(ParseException e) {
if (e != null) {
Toast.makeText(getApplicationContext(),
"Saving user failed." + e.getMessage(), Toast.LENGTH_SHORT).show();
if (e.getCode() == 202) {
Toast.makeText(
getApplicationContext(),
"Username already taken. \n Please choose another username.",
Toast.LENGTH_LONG).show();
}
} else {
Toast.makeText(getApplicationContext(), "User Saved",
Toast.LENGTH_SHORT).show();
/*Do some things here if you want to.*/
}
}
});
}
}

在尝试注册用户之前,您需要等待Parse文件完成保存。你需要做这样的事情:
photo = new ParseFile("userpicture.png", Image);
file.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
// If successful add file to user and signUpInBackground
if(null == e)
savetoParse();
}
});

我遇到了同样的问题,但后来我想保存图像需要先登录,因此可以使用ParseUser.LogInBackGround
方法使用用户名和密码登录,或者使用Parse.enableLocalDatastore(this);
启用自动创建用户并登录。
