Shared preferences logging system in android

Shared preferences logging system in android - java

I searched in stackoverflow and i could not find anything like this. I want to make a logging system like registration and login. But the following code does not work when clicked LogIN. There is probably error in the if logic. please help'.
MainActivity.java

public static final String MyPREFERENCES = "MyPrefs" ;
public static final String email = "emailKey";
public static final String password = "passwordKey";
public static final String safety = "safetyKey";
SharedPreferences sharedpreferences;
SharedPreferences sharedpreferences2;
//

sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
b1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email = ed1.getText().toString();
String password = ed2.getText().toString();
if(sharedpreferences.getString(password,"").equals(password))
Toast.makeText(MainActivity.this, "Logged on Successful", Toast.LENGTH_SHORT).show();
}
});
b2.setOnClickListener(new View.OnClickListener() {
#Override

String email = ed1.getText().toString();
String password = ed2.getText().toString();
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(email,email);
editor.putString(password,password);
editor.commit();
Toast.makeText(MainActivity.this,"Thanks! Signed up",Toast.LENGTH_LONG).show();
}
});
}
}

I think there is something wrong with you understanding of SharedPref. It stores key-value pairs. If you use the same key to store all the emails, you would still need a way to correlate between the username and the password. One way to achieve this could be to do something like this:
String email = ed1.getText().toString();
String password = ed2.getText().toString();
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(email, password);
editor.commit();
Then, retrieval would be as simple as...
String email = ed1.getText().toString();
String password = ed2.getText().toString();
if(sharedpreferences.getString(email,"").equals(password))
** LOG USER IN **
An alternative way is to store all emails with the same key, and all passwords with the same key. Here, you would need to do something to ensure that emails and the passwords are connected to each other. One way could be to append email to the end of the password, and then save it.
String email = ed1.getText().toString();
String password = ed2.getText().toString();
password += email;
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(this.email,email);
editor.putString(this.password,password);
editor.commit();
Instead of using getString(..) you would now need to use [getStringSet].
Edit.
It would also be a good idea to change the names of these 2 fields.
public static final String email = "emailKey"; // to emailKey
public static final String password = "passwordKey"; // to passwordKey
This will avoid confusion with the contents of the EditText boxes.

Get value of a EditText in another layout

I have an dialog that appears where the user can costumize how many points they get from each action. The dialog is based on a layout that is not the main_activity. the main activity is the layout that is used in setContentView in the onCreate method.
when I try to get the values I am only getting null, (because the layout where the EditText is is not set as the contentview.... maybe?)
How do I solve this problem so that I get the value of the edittext in the "settings" layout and can use that value in the MainActivity?

private int teamTwoPoints=0;

I would strongly recommend using SharedPreferences. This way, you can access the data even if you restart your application. If that does not work for you, you can use Intent.
Consider reading this StackOverflow post.
Using SharedPreferences:
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(getString(R.string.points), pointsPerActivity);
editor.commit();
SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
int defaultValue = 1;
// or you can store the value somewhere
// getResources().getInteger(R.integer.defaultPointsPerActivity);
int pointsPerActivity = sharedPref.getInt(pointsPerActivity, defaultValue);

pass view object in applySettings(v);
private int teamOnePoints=0;
private int teamTwoPoints=0;
private boolean teamOneField=true;
private int burnedPoints = 1;
private int lyrePoints= 3;
private int oneHandLyrePoints = 5;
private int homeRunPoints=5;
private int revPoints=1;
private String teamOneName = "Lag 1";
private String teamTwoName = "Lag 2";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ToggleButton toggle = (ToggleButton)
findViewById(R.id.field_team_toggle); //activates toggle button
toggle.setOnCheckedChangeListener(new
CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean

} else {
teamOneField=true;
}
}
});
FloatingActionButton fab = findViewById(R.id.points_edit_button);
fab.setOnClickListener(new View.OnClickListener() {

I have a main activity (mottoscreen) after which an activity called circles opens up then from that activity I want to open up either one of the other two activities(sc_activity and or_activity). I have written the code for it but on clicking the buttons present in circles activity the next activity isn't showing up.
Circles Java file-
package com.apsdevelopers.mr.meteout;
import android.content.Intent;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
public class circles extends mottoscreen {
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.circles);
}
public void onButtonClick(View v)
{
if (v.getId() == R.id.GOsc)
{
Intent I = new Intent(circles.this, sc_activity.class);
startActivity(I);
}
else if (v.getId() == R.id.GOor)
{

startActivity(j);
}

Please guide me where I did a mistake in the code.

Can you please check the following in your code:
Your circles.xml has two Buttons with id GOsc and GOor?
In your circles.xml you have set android:onClick="onButtonClick"for both buttons?
If both of the above result to yes, can you please paste your circles.xml file here as well?

Can't set values in second activity

So I'm making a simple application that just takes some information from the user i.e Name, address etc and puts it in the the textviews in the next activity but when I put in the values and move to the next activity there's nothing displayed in the TextViews.
Here's my first activity
public class MainActivity extends Activity {
public String Name;
public String Age;
public String Address;
public String City;
public String phoneno;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText name = (EditText) findViewById(R.id.editText1);
Name = name.getText().toString();
EditText Amge = (EditText) findViewById(R.id.agee);
Age = Amge.getText().toString();
EditText Address2 = (EditText) findViewById(R.id.address);
Address = Address2.getText().toString();
EditText City2 = (EditText) findViewById(R.id.city);
City = City2.getText().toString();
EditText phone2 = (EditText) findViewById(R.id.phone);
phoneno = phone2.getText().toString();
final ImageView D = (ImageView) findViewById(R.id.done);
D.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this, second.class);
startActivity(intent);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);}}
Here's my second activity
public class second extends MainActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
TextView N1 = (TextView) findViewById(R.id.name1);
N1.setText(Name);
TextView A1 = (TextView) findViewById(R.id.age1);
A1.setText(Age);
TextView Ad1 = (TextView) findViewById(R.id.address1);
Ad1.setText(Address);
TextView C1 = (TextView) findViewById(R.id.city1);
C1.setText(City);
TextView P1 = (TextView) findViewById(R.id.phone1);
P1.setText(phoneno);}
public static void main(String[] args) {

After you declare your Intent , try sending your data with this
//this use key-value
intent.putExtra("USER_NAME" , "your string");
intent.putExtra("USER_AGE" , "your string");
and etc.
and to other Activity try use
Bundle extra = getIntent().getExtras();
String userName = extra.getString("USER_NAME");
String userAge = extra.getString("USER_AGE");

When you declare your Intent here:
Intent intent = new Intent(MainActivity.this, second.class);
Try sending some data with it using Extras based on what view is being clicked on
For example:
intent.putExtra(Intent.EXTRA_INTENT, **Your String Here**);
And in the activity receiving the intent, use something like:
String data = intent.getStringExtra(Intent.EXTRA_INTENT);
To fetch the data from the intent

Below is the logcat shown in ecplise
i just change the id of edit text in login xml,is solve the ClassCastException error..
<
EditText android:layout_width="fill_parent"
android:id="#+id/loginEmail"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
android:layout_marginBottom="20dip"
android:singleLine="true" />
Now is become a new error, "java.lang.NullPointerException"..So where is the reason again ya??
All experts here pls take a look ya.pls help..thank you

Your button doesn't do anything because the following two lines in LoginActivity throw a ClassCastException because you can't cast from an Android.widget.TextView to an Android.widget.EditView.
inputEmail = (EditText) findViewById(R.id.loginEmail);
inputPassword = (EditText) findViewById(R.id.loginPassword);
In main.xml change the first two <TextView ... /> to <EditText ... /> :
<TextView
android:id="#+id/textView1"
...
android:textAppearance="?android:attr/textAppearanceLarge" />
Change to :
<EditText
android:id="#+id/textView2"
...
android:textAppearance="?android:attr/textAppearanceLarge" />

I need value of gender in float idealweight = idealweight(weight, height, gender, pa, age); and also double dailycalories=dailycalories(weight,height,gender,pa,age);
can any one help me?

String sex = null;
...
onCheckedChanged(RadioGroup arg0, int selectedId){
if(selectedId == R.id.femaleselected){
sex = "female";
} else {
sex = "male";
}
}
Hope this helps.

follow these steps:
add member String mGender to your activity.
MainActivity extend ...
String mGender = null;
onCreate ...
replace the gender by mGender and everything should work
onClick(View v) {
if(mGender != null){
// use mGender
// float gender = Float.valueOf(mGender);
//double gender = Double.valueOf(mGender);
}
}

genderselected.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener()
{
#Override
public void onCheckedChanged(RadioGroup arg0, int selectedId)
{
switch(selectedId)
{
case R.id. femaleselected:
Log.d("","female selected");
break;
case R.id. maleselected:
Log.d("","male selected");
break;
}
}
});
