Login to Facebook using Dialog in Android
How to implement this login using facebook? I followed this tutorial https://www.androidlearning.in/facebook-login-for-android-app/ but it generates full activity (traditional way).
I have facebook app installed
In applications like Memrise, Bandlab, etc. Shows me what Dialog is but not in my application
Also I am trying with
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList([...]);
but doesn't work ...
I want to:

I faced the same problem as you 30 minutes ago, but I used a custom Facebook button and the following code inside onCreate to call Facebook Login:
loginButton = (CircularProgressButton) findViewById(R.id.btn_fb);
loginButton.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View v) {
LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("public_profile", "user_friends"));
}
});
//Register a callback
callbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object,GraphResponse response) {
try {
nome = object.getString("name");
email = object.getString("email");
String idfb = loginResult.getAccessToken().getUserId();
logarFb(idfb, nome, email);
} catch(JSONException ex) {
ex.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
//cancelled
}
@Override
public void onError(FacebookException exception) {
//error
}
});
I changed it to a Facebook login button:
<com.facebook.login.widget.LoginButton
android:id="@+id/btn_fb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="30dp"
android:layout_marginBottom="30dp" />
Now that my code looks now much cleaner:
private LoginButton loginButton;
private CallbackManager callbackManager;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
callbackManager = CallbackManager.Factory.create();
loginButton = findViewById(R.id.btn_fb);
loginButton.setReadPermissions("email");
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
getUserDetails(loginResult);
}
@Override
public void onCancel() {
funcoes.aviso(MainActivity.this,"Você cancelou o login",R.color.red500,3000, R.drawable.ic_triste);
}
@Override
public void onError(FacebookException exception) {
funcoes.dialogoMsg(MainActivity.this,"Há algo de errado com o login do Facebook :/");
}
});
}
protected void getUserDetails(final LoginResult loginResult) {
GraphRequest data_request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted( JSONObject object, GraphResponse response) {
try {
nome = object.getString("name");
email = object.getString("email");
String idfb = loginResult.getAccessToken().getUserId();
logarFb(idfb, nome, email);
} catch(JSONException ex) {
ex.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
data_request.setParameters(parameters);
data_request.executeAsync();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
If you have the Facebook app installed, this should be enough so that instead of entering full screen mode, instead of entering full screen mode, Facebook login is enabled as a dialog box.
