我创建了一个项目。我得到图形对象。现在我想将这些数据设置为textView.I使用facebook sdk v4 +。我的代码在这里。

{
Log.i("Login", "ProfilePic" + Profile.getCurrentProfile().getProfilePictureUri(200, 200));
}
// Log.i("Login" + "Email", email);
Log.i("Login"+ "FirstName", firstName);
Log.i("Login" + "LastName", lastName);
Log.i("Login" + "Gender", gender);
Log.i("Login" + "Bday", bday);
// Intent intent=new Intent(getApplicationContext(),NextClass.class);
// //intent.putExtra("Firstname", username1);
// startActivity(intent);
// tv.setText(firstName + " " + lastName + " " + gender + " " + bday);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,first_name,last_name,gender,birthday");
request.setParameters(parameters);
request.executeAsync();
}
}
在此我得到回应。但我无法将该响应转换为字符串。意味着无法获得字符串电子邮件，名字等。
任何人都可以帮助我？

我们假设您有一个TextView对象mTextView
看看这里说setText的代码吧！
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(final JSONObject object, GraphResponse response) {
// Application code
try {
Log.i("Response", response.toString());
String email = response.getJSONObject().getString("email");
String firstName = response.getJSONObject().getString("first_name");
String lastName = response.getJSONObject().getString("last_name");
String gender = response.getJSONObject().getString("gender");
String bday= response.getJSONObject().getString("birthday");
Profile profile = Profile.getCurrentProfile();
String id = profile.getId();
String link = profile.getLinkUri().toString();
Log.i("Link",link);
if (Profile.getCurrentProfile()!=null)
{
Log.i("Login", "ProfilePic" + Profile.getCurrentProfile().getProfilePictureUri(200, 200));
}
Log.i("Login" + "Email", email);
Log.i("Login"+ "FirstName", firstName);
Log.i("Login" + "LastName", lastName);
Log.i("Login" + "Gender", gender);
Log.i("Login" + "Bday", bday);
//Textview set here
mTextView.setText(email + " " +firstName+ " " + lastName + " " + gender +" " + bday);
} catch (JSONException e) {
e.printStackTrace();
}
}
});

您已从JSONObject方法获得onCompleted。因此，只需从JSONObject object本身获取所有必需值。
跟着这个。
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(final JSONObject object, GraphResponse response) {
// Application code
try {
Log.i("Response", response.toString());
String email = object.getString("email");
String firstName = object.getString("first_name");
String lastName = object.getString("last_name");
String gender = object.getString("gender");
String bday= object.getString("birthday");
Profile profile = Profile.getCurrentProfile();
String id = profile.getId();
String link = profile.getLinkUri().toString();
Log.i("Link",link);
if (Profile.getCurrentProfile()!=null)
{
Log.i("Login", "ProfilePic" + Profile.getCurrentProfile().getProfilePictureUri(200, 200));
}
Log.i("Login" + "Email", email);
Log.i("Login"+ "FirstName", firstName);
Log.i("Login" + "LastName", lastName);
Log.i("Login" + "Gender", gender);
Log.i("Login" + "Bday", bday);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
