Here def no getting message as Couldn't load data
please help me
Replace with this:
DefaultData = getSharedPreferences("defMobileNo",0);
final String defNo = DefaultData.getString("defMobileNo","Couldn't load data");
final String defMsg = DefaultData.getString("defMessgae","Couldn't load data");
This is how basically sharedpreference work
To Store the values
SharedPreferences preferences = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_WORLD_WRITEABLE);
SharedPreferences.Editor editor = preferences.edit();
editor.putString("Name","myNameisnothing");
editor.commit();
To get the values
SharedPreferences prfs = getSharedPreferences("AUTHENTICATION_FILE_NAME", Context.MODE_PRIVATE);
String name = prfs.getString("Name", "");
This way it'd return the value of the name as myNameisnothing.
PS.Correct me if im wrong.
You are wrongly using
DefaultData = getSharedPreferences("defMessgae",0); in DefSMS.java
Please remove this and it will work fine.
You were trying to get shared preference named defMessgae which doesnot even exist. So when you try to access it, android will create a new preference with default value. That is why you were getting "Couldn't load data"

You shouldn't be using static variables for view members because you might get memory leaks. Also the views you are referencing are destroyed when activity is destroyed, so they are not accessible in your second activity. You can send checkboxes checked values as intent extras.
Put this in your Activity 1 in OnClick1() method:
Intent i=new Intent(this,MyCart.class);
i.putExtra("cb1", cb1.isChecked());
i.putExtra("cb2", cb2.isChecked());
i.putExtra("cb3", cb3.isChecked());
startActivity(i);
This is how you get values in Activity 2 (in onCreate() method):
Intent intent = getIntent();
if(intent.getBooleanExtra("cb1", false)){
String price11 = sp1.getString("price1", "");
tv4.setText(price11);
}
if(intent.getBooleanExtra("cb2", false)){
String price21=sp1.getString("price2","");
tv5.setText(price21);
}
if(intent.getBooleanExtra("cb3", false)){
String price31=sp1.getString("price3","");
tv6.setText(price31);
}
public void OnClick1(View view)
{
if(view.getID() == R.id.cb1)
{
if(cb1.isChecked())
editor.putBoolean("x",true);
else
editor.putBoolean("x",false);
}
}
In your second activity
sp1=getSharedPreferences("SHOPPING",MODE_PRIVATE);
boolean isChecked = sp1.getBoolean("x", false);
if(isChecked){
String price11 = sp1.getString("price1", "");
tv4.setText(price11);
}

If you want to see how a Cursor loader can work for you, you can review the following project that I have uploaded to github: GPS Distance Tracking
I'm developing a simple game in Android and even i followed the steps found in the net, the highscore of my app is never saved. I'm using SharedPreferences to store, but I'm quietly sure the problem is in there, because I don't understand at all how to use it.Hope you guys can help me, thanks.

menu.setOnClickListener(this);
intent = getIntent();
levelReached = intent.getIntExtra("nivel", 1);
SharedPreferences preferences = this.getSharedPreferences("bestScore", MODE_PRIVATE);
int savedScore = preferences.getInt("selectedScore", 0);
levelReachedText.setText("You reached level "+levelReached );
if(savedScore>levelReached){
bestScore = savedScore;
}else{
bestScore = levelReached;
}
bestScoreText.setText("Maximum level reached "+levelReached);
}

case R.id.inicio:
SharedPreferences preferences = this.getSharedPreferences("mejorScore", MODE_PRIVATE);
preferences.edit().putInt("selectedScore", bestScore).commit();
this.finish();
break;
}
}
}
you are saving score value in mejorScore and trying to get it from bestScore.So either change
SharedPreferences preferences = this.getSharedPreferences("mejorScore", MODE_PRIVATE);
to
SharedPreferences preferences = this.getSharedPreferences("bestScore", MODE_PRIVATE);
or vice-versa.
I am working on an android code and trying to update the user information. I am able to retrieve the information but have not been able to update. Not sure what I am doing wrong.
In the if-else statement, it does not hit the If statement, goes directly to the error(else statement.
here is the code
package com.example.autrui;
import com.parse.GetCallback;
import com.parse.ParseACL;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import com.parse.ParseUser;
import com.parse.SaveCallback;
import com.parse.SendCallback;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class EditPP extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.editpp);
final Button confirmChangeEditPP = (Button) findViewById(R.id.bconfirmChangeEditPP);
final EditText fullName = (EditText) findViewById(R.id.etFullName);
final EditText email = (EditText) findViewById(R.id.etEmail);
//final ParseUser currentUser = new ParseUser();
final ParseUser currentUser = ParseUser.getCurrentUser();
System.out.println(currentUser);
String objectId = currentUser.getObjectId();
System.out.println(objectId);
String fName = currentUser.getString("fullName");
fullName.setText(fName);
email.setText(currentUser.getString("email"));
ParseQuery<ParseObject> userQuery = ParseQuery.getQuery("User");
userQuery.getInBackground((String)objectId, new GetCallback<ParseObject>(){
public void done(final ParseObject object, ParseException e) {
if (e == null) {
confirmChangeEditPP.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ParseACL acl = new ParseACL();
acl.setPublicReadAccess(true);
acl.setPublicWriteAccess(true);
currentUser.setACL(acl);
object.put("fullName", fullName.getText().toString());
object.put("email", email.getText().toString());
object.saveInBackground();
}
});
} else {
Log.e("error","error");
}
}
});
}
#Override
public void onBackPressed() {
finish();
// Go to settings
/*
* if(MainActivity.s.isEmpty()) return; else { View v =
* MainActivity.s.pop(); Class c = MainActivity.s2.pop(); Intent intent
* = new Intent(v.getContext(), c); startActivityForResult(intent, 0); }
*/
}
private void showUserDetailsActivity() {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
}
}
I got the answer. the error was regarding the ACL and yes we did not need the query. I wrote the whole code again and made it simpler.
I am trying to have it so when you click one of the answeers (Q1A1 or Q1A2) it will add a number of points to the testScore int so I can then later call that in a later class so the score they got would be posted there. Thanks to anyone who helps in advance!
here's my code,
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
public class Test extends Activity implements OnClickListener
{
TextView Q1A1;
TextView Q1A2;
TextView test;
public static final String PREFS_NAME = "MyPrefsFile";
public static final int testScore = 0;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
Q1A1 = (TextView) findViewById(R.id.Q1A1);
Q1A2 = (TextView) findViewById(R.id.Q1A2);
Q1A1.setOnClickListener(this);
Q1A2.setOnClickListener(this);
test = (TextView) findViewById(R.id.test);
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
test.setText(settings.getString("YourScore", "No Score"));
}
public void onClick(View v)
{
switch(v.getId())
{
case R.id.Q1A1:
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putInt("YourScore", (testScore + 10));
editor.commit();
//Intent FinalScore = new Intent(this, FinalScore.class);
//startActivity(FinalScore);
break;
case R.id.Q1A2:
break;
}
}
}
thanks for the help
You are are saving your score as an int but calling it as a string.
Change
test.setText(settings.getString("YourScore" , "No Score"));
To
test.setText(""+settings.getInt("YourScore" , 0));
