I have a fragment which has two buttons. I have implemented view.OnclickListener methods, and set onclickistener on both buttons:
btn_password = (ImageButton) v.findViewById(R.id.btn_password);
btnEditar = (Button) v.findViewById(R.id.btnEditar);
btn_password.setOnClickListener(this);
btnEditar.setOnClickListener(this);
Then I have implemented the onclick method:
#Override
public void onClick(View view) {
Fragment fragment = null;
switch (view.getId()) {
case R.id.btnEditar:
registerUser(empresa,nombre,direccion,cif,tel,cuenta,id );
break;
case R.id.btn_password:
Log.d(TAG, "Register Response: id" + "clicked Change Password" );
Intent intent1 = new Intent(getActivity(), CambiarPasswordActivity.class);
startActivity(intent1);
break;
}
}
To check that btn_password is clicked, I have included a log, that confirms that the button is clicked.
My issue is that the intent is not launching the activity, it opens MainActivity which is the activity that holds the current fragment.
Any help is welcome

Try this one.
#Override
public void onClick(View view) {
Fragment fragment = null;
switch (view.getId()) {
case R.id.btnEditar:
registerUser(empresa,nombre,direccion,cif,tel,cuenta,id );
break;
case R.id.btn_password:
Log.d(TAG, "Register Response: id" + "clicked Change Password" );
Intent intent1 = new Intent(getActivity(), CambiarPasswordActivity.class);
getActivity().startActivity(intent1);
break;
}
}
So the actual problem is
if (!session.isLoggedIn()) {
logoutUser();
}
Your logoutUser() method was executing because of session.isLoggedIn() returning
false. As the above if condition is satisfying and from logoutUser() you are Launching Intent for LoginActivity.
Which become problem, so you need to handle session.isLoggedIn() according to your requirement.
Thanks
Try this:
In the activity that holds the fragment (MainActivity), create a method that launches CambiarPasswordActivity, and make it public.
MainActivity.class
public void launchCambiarPasswordActivity(){
startActivity(new Intent(this, CambiarPasswordActivity.class));
}
2. And call this method from the fragment:
YourFragment.class
#Override
public void onClick(View view) {
Fragment fragment = null;
switch (view.getId()) {
case R.id.btnEditar:
registerUser(empresa,nombre,direccion,cif,tel,cuenta,id );
break;
case R.id.btn_password:
Log.d(TAG, "Register Response: id" + "clicked Change Password" );
// Call the new method.
((MainActivity) getActivity()).launchCambiarPasswordActivity();
break;
}
}

p.s i am new to android so gives answers with coding and try to replace my code with ur correct code...thx in advance
You can use shared preferences, save your user name in your shared preferences,
and put check on the main launching activity (for example if you login activity as launcher activity), if username exists then redirect user to some other activity using intent otherwise ask user to login again.
Hope it helps you.
when I login for the very first time i did this after login(read about shared preferences if you don`t know how to use it)
CommonObjects.saveSharedPreferences(Login.this, "user_id", user_id);
CommonObjects.saveSharedPreferences(Login.this, "name", name);
this i close my app and open app again, hence my login activity is the first activity which always shows first when i open my app, then in very beginning of the of the login activity do this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
if (CommonObjects.hasSharedPreference(context,"user_id")){
Intent intMain=new Intent(Login.this,DashboardActivity.class);
startActivity(intMain);
finish();
}
}
hope you understand now.

For this you can use "SharedPreferences".
When a user logs into the application, save a boolean variable say: "USERLOGGED_IN" into the shared preferences, like this:
The below code is to be written inside "AsyncTask":
SharedPreferences prefs;
Editor editor = prefs.edit();<br></br>
editor .putBoolean("USERLOGGED_IN",true); //If user has logged in successfully<br></br>
//or
editor .putBoolean("USERLOGGED_IN",false);//If user has not logged in<br></br>
editor.commit();
Once the value has been saved in the "SharedPreferences", the only thing left is to check this value, when a user opens the application again.
Then do this:
SharedPreferences prefs;
boolean USERLOGGED_IN = prefs.getBoolean("USERLOGGED_IN"); // the value you saved during logging in the user.
if(USERLOGGED_IN == true)
{
//User has logged in already, so direct the user to home screen.
}
else
{
//User is new, so direct the user to login screen.
}
I hope this helps.
I started learning Android and Java a week ago and now I am trying to make an login application. I am using Volley libary to communicate with my server. I have done the login part. Now, what I want to do is to check the database every minute to see if the password or the username somehow changed. If the information in the database is changed, app will automaticly logout the user.
If you can explain which tools(Services,BroadcastReceivers) I can use and how can I achieve it, as I am not very experienced.
This is what I tried and failed:
loginChecker.class
public class loginChecker extends Service {
public loginChecker() {
}

public static String password;
private loginChecker mInstance = this;
public static boolean loginCheck= true;

username = b.getString("username");
password = b.getString("password");

final RequestQueue requestQueue = Volley.newRequestQueue(mInstance);
new Thread(new Runnable(){
public void run() {
do{
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
StringRequest request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
responseG = response;
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
responseG = "error";
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> hashMap = new HashMap<String, String>();
hashMap.put("username", username);
hashMap.put("password", password);
return hashMap;
}
};
requestQueue.add(request);
switch(responseG){
case "successful" :
loginCheck = true;
break;
case "failed" :
loginCheck= false;
break;
case "error" :
loginCheck = false;
break;
}
}
while(loginCheck == true || responseG == "successful");
}
}).start();

loginCheckerService.putExtras(b);

finish();
break;

There is also a file called Profile.class but it is empty. I tried this but the loop lasted one tour. It stopped even though the connection was ok and the data wasn't changed.
Hi in the below code when clicking the report button not going to login activity even though it's not happening anything.
In login activity first of all I am checking the login username and password using session object.
if the username and password working fine and then want to move to next activity.
Can any one help me from this issue.
Mainactivity.java
report1=(TextView)findViewById(R.id.report1);
report=(ImageView)findViewById(R.id.report);
report1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});
report.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(getApplicationContext(),Login.class);
startActivity(i);
}
});
In the below when I am putting comment for session then it's moving but after entering the username and password it was showing logcat Admin user found but not going to next activity.it was staying in same activity itself.

Do not use the application's context, use the context the view currently be presented.
report.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent i=new Intent(v.getContext(), Login.class);
startActivity(i);
}
});
