Android WebView Set Login Status to True after Successful Login

I’m using Shared Preferences to store user data and set Login Status in a web view app for eCommerce Website. The user can either login via Login URL or at the Checkout Page. The issue I’m facing I can’t set Login status to “True” after the user successfully logged in so I can retrieve the username it keeps showing as "False".
EDIT: After posting the question I was able to find part of the solution for the Login URL to set the status to true however the CARTURL isn't working. I defined isRedirected = true; and set the condition to get the right status.
I'm reposting the code after edit:
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.e(TAG, "should override url loading" + url);
view.loadUrl(url);
isRedirected = true;
return true;
}
public void onPageFinished(WebView view, String url) {
//webView.setClickable(true);menuBtn.setClickable(true);cartImg.setClickable(true);logoImg.setClickable(true);
Log.e(TAG, "on page finished" + url);
Log.e(TAG, "is logged in==" + isLoggedin);
isRedirected = true;
String isLoggedin = "false";
if(url.equals(Constants.ACCOUNTURL) && isRedirected && isLoggedin.equals("false")) {
Log.e(TAG, "reload");
//webView.loadUrl(Constants.ACCOUNTEDITURL);
SharedPreferences pref = getApplicationContext().getSharedPreferences("Login", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putString("isLogedin", "true");
editor.commit();
setWelcome();
Toast toast = Toast.makeText(MainActivity.this, "You have signed in", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
};
if(url.equals(Constants.CARTURL) && isRedirected && isLoggedin.equals("false")) {
Log.e(TAG, "Cart Login");
//webView.loadUrl(Constants.ACCOUNTEDITURL);
SharedPreferences pref = getApplicationContext().getSharedPreferences("Login", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putString("isLogedin", "true");
editor.commit();
setWelcome();
Toast toast = Toast.makeText(MainActivity.this, "You have signed in", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
};
//if(url.equals(Constants.LOGOUTURL) && isLoggedin.equals("true")) {
if(url.equals(Constants.LOGOUTURL)) {
Log.e(TAG, "logging out-----------------");
SharedPreferences pref = getApplicationContext().getSharedPreferences("Login", MODE_PRIVATE);
SharedPreferences.Editor editor = pref.edit();
editor.putString("isLogedin", "false");
//editor.clear();
editor.commit();
setWelcome();
Toast toast = Toast.makeText(MainActivity.this, "You have logged out", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
//return;
}
if(isLoggedin.equals("true")) {
Log.e(TAG, "in get name-----------------");
mainView.addJavascriptInterface(new myJavaScriptInterface(), "CallToAnAndroidFunction");
//String getnamejs = "(document.getElementById('input-firstname').value);";
String getnamejs = "(document.getElementById('app_customer_name').innerHTML);";
mainView.loadUrl("javascript: window.CallToAnAndroidFunction.getUserName" + getnamejs);
}
Your help is highly appreciated, thank you in advanced.

Do you mean that the string variable isLoggedin is always false? could you mention where are you assigning the value for the variable isLoggedin.

Please try the below code, I have modified the putString with boolean.
boolean isLoggedin;
SharedPreferences pref =
getApplicationContext().getSharedPreferences("Login", MODE_PRIVATE);
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.e(TAG, "should override url loading" + url);
view.loadUrl(url);
isRedirected = true;
return true;
}
public void onPageFinished(WebView view, String url) {
Log.e(TAG, "on page finished" + url);
isLoggedin = pref.getBoolean(“isLoggedin”, false);
if (url.equals(Constants.ACCOUNTURL) && url.equals(Constants.CARTURL) && !isLoggedin) {
Log.e(TAG, "reload");
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean(“isLoggedin", true);
editor.commit();
setWelcome();
Toast toast = Toast.makeText(MainActivity.this, "You have signed in", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
Log.e(TAG, "in get name-----------------");
mainView.addJavascriptInterface(new myJavaScriptInterface(), "CallToAnAndroidFunction");
//String getnamejs = "(document.getElementById('input-firstname').value);";
String getnamejs = "(document.getElementById('app_customer_name')[0].innerHTML);";
mainView.loadUrl("javascript: window.CallToAnAndroidFunction.getUserName" + getnamejs);
}
//if(url.equals(Constants.LOGOUTURL) && isLoggedin) {
if (url.equals(Constants.LOGOUTURL)) {
Log.e(TAG, "logging out-----------------");
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("isLoggedin", false);
//editor.clear();
editor.commit();
setWelcome();
Toast toast = Toast.makeText(MainActivity.this, "You have logged out", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
//return;
}
Let me know if that helps!

SharedPreferences always shows the same thing

So I'm trying to save a value to sharedpreferences by a click of a button, and then see which value it is in another activity. (to basically set a background for activity2 based on which button they pressed in activity1)
Saving code:
public void onClick(View v) {
SharedPreferences.Editor background = getSharedPreferences("Background", MODE_PRIVATE).edit();
if(btn1 == v)
{
background.remove("selectedBG");
Toast.makeText(this, "btn1", Toast.LENGTH_SHORT).show();
background.putInt("selectedBG", 1);
background.commit();
}
if(btn2 == v)
{
background.remove("selectedBG");
background.putInt("selectedBG", 2);
Toast.makeText(this, "btn2", Toast.LENGTH_SHORT).show();
background.commit();
}
if(btn3 == v)
{
background.remove("selectedBG");
background.putInt("selectedBG", 3);
Toast.makeText(this, "btn3", Toast.LENGTH_SHORT).show();
background.commit();
}
if(btn4 == v)
{
background.remove("selectedBG");
background.putInt("selectedBG", 4);
Toast.makeText(this, "btn4", Toast.LENGTH_SHORT).show();
background.commit();
}
}
And then, the Toast here always shows "chosenbackground:0":
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.play);
LLayout=(LinearLayout)findViewById(R.id.llayout);
SharedPreferences background2 = getSharedPreferences("Background", MODE_PRIVATE);
int chosenBackground = background2.getInt("selectedBg", 0);
Toast.makeText(this,"chosenBackground:" + chosenBackground, Toast.LENGTH_SHORT).show();
if (chosenBackground != 0) {
if(chosenBackground==1)
{
LLayout.setBackgroundColor(Color.WHITE);
}
if(chosenBackground==2)
{
LLayout.setBackgroundColor(Color.rgb(34,34,34));
}
if(chosenBackground==3)
{
LLayout.setBackgroundColor(Color.rgb(51,68,85));
}
if(chosenBackground==4)
{
LLayout.setBackgroundColor(Color.rgb(68,34,17));
}
}
}

Answer for your question is that you have misspelled the key in second activity, in first one you are using "selectedBG" but in the second one "selectedBg". It is not the same, it's case sensitive. Correct in the second one for "selectedBG" and it should work.

Using the SharedPreferences here it's really bad idea, if u only want to pass a background or rather a color if I see it correctly. Just pass it in intent:
Intent intent = new Intent(this, Activity2.class);
intent.putExtra("EXTRA_BACKGROUND_ID", background);
startActivity(intent);
Access that intent on next activity for eg. in onCreate()
String s = getIntent().getStringExtra("EXTRA_SESSION_ID");
#Updated
public class PreferencesUtils {
private SharedPreferences sharedPrefs;
private SharedPreferences.Editor prefsEditor;
public static final String KEY_BACKGROUND = "BACKGROUND";
public PreferencesUtils(Context context) {
this(context, PREFS_DEFAULT);
}
public PreferencesUtils(Context context, String prefs) {
this.sharedPrefs = context.getSharedPreferences(prefs, Activity.MODE_PRIVATE);
this.prefsEditor = sharedPrefs.edit();
}
public int getValue(String key, int defaultValue){
return sharedPrefs.getInt(key, defaultValue);
}
public boolean saveValue(String key, int value){
prefsEditor.putInt(key, value);
return prefsEditor.commit();
}
}
PreferencesUtils preferencesUtils = new PreferencesUtils(this);
preferencesUtils.saveValue(PreferencesUtils.KEY_BACKGROUND, 1); //saveValue
preferencesUtils.getValue(PreferencesUtils.KEY_BACKGROUND, 0); //getValue,
second arg is defult if not found

Use if (!background2.contains("selectedBg"))
to check ,first whether the key exists and if not getInt is not able to create a key and hence always returns default value 0.Also you can use apply() instead of commit to check whether commit has taken place successfully.Debug the code more to see all possibilities
int chosenBackground=0;
if (!background2.contains("selectedBg"))
{
//is called once when after you freshly install the app
background2.putInt("selectedBG", 0);
}
else
chosenBackground = background2.getInt("selectedBg", 0);

How to make the app go to another page if it is not run by first time

I have RegisterPage and LoginPage. When the app is run, it will check whether the app is first time run or not in RegisterPage. If it is first time run and the save button is not clicked, it will in RegisterPage. If it is run second times but the save button is never clicked, it will remain in RegisterPage too. Otherwise it will go to LoginPage.
Here my updated code
Register
appGetFirstTimeRun();
boolean clicked=false;
buttonSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clicked=true;
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
appPreferences.edit().putInt("app_second_time",
appCurrentBuildVersion).apply();
String name = editTextName.getText().toString();
String pass = editTextPassword.getText().toString();
String confirm = editTextConfirm.getText().toString();
if ((editTextName.getText().toString().trim().length() == 0) || (editTextPassword.getText().toString().trim().length() == 0) || (editTextConfirm.getText().toString().trim().length() == 0)) {
Toast.makeText(getApplicationContext(), "Field cannot be null", Toast.LENGTH_LONG).show();
}
else
{
insertData(name, pass, imageUri); // insert to SQLite
Intent intent = new Intent(MainActivity.this, AddMonthlyExpenses.class);
intent.putExtra("name", name);
startActivity(intent);
}
}
});
private int appGetFirstTimeRun() {
//Check if App Start First Time
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
int appLastBuildVersion = appPreferences.getInt("app_first_time", 0);
if (appLastBuildVersion == appCurrentBuildVersion && clicked) {
Intent intent = new Intent(MainActivity.this,LoginPage.class);
startActivity(intent);
return 1;
} else {
appPreferences.edit().putInt("app_first_time",
appCurrentBuildVersion).apply();
if (appLastBuildVersion == 0) {
Toast.makeText(getApplicationContext(), "First time", Toast.LENGTH_SHORT).show();
return 0; //es la primera vez
} else {
return 2; //es una versión nueva
}
}
}
The problem is when I click the save button and exit from the app. When I run the app again it still in the RegisterPage, not in LoginPage.

Check button click after inserting data into SQLite, So you can confirm that your data has successfully saved and you can proceed to next screen.
Find my comments in below code and edit your code:-
public class Register extends AppCompatActivity {
Button buttonSave;
boolean clicked=false;//remove this
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
appGetFirstTimeRun();//call this method here
buttonSave=(Button)findViewById(R.id.button);
buttonSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
clicked=true;//remove this
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
appPreferences.edit().putInt("app_second_time", appCurrentBuildVersion).apply();
String name = editTextName.getText().toString();
String pass = editTextPassword.getText().toString();
String confirm = editTextConfirm.getText().toString();
if ((editTextName.getText().toString().trim().length() == 0) || (editTextPassword.getText().toString().trim().length() == 0) || (editTextConfirm.getText().toString().trim().length() == 0)) {
Toast.makeText(getApplicationContext(), "Field cannot be null", Toast.LENGTH_LONG).show();
}
else
{
insertData(name, pass, imageUri); // insert to SQLite
appPreferences.edit().putBoolean("btn_clicked", true).apply();//add this line
Intent intent = new Intent(Register.this, AddMonthlyExpenses.class);
intent.putExtra("name", name);
startActivity(intent);
}
}
});
}
private int appGetFirstTimeRun() {
//Check if App Start First Time
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
int appLastBuildVersion = appPreferences.getInt("app_first_time", 0);
boolean is_btn_click=appPreferences.getBoolean("btn_clicked",false);//add this line
if ((appLastBuildVersion == appCurrentBuildVersion) && is_btn_click) { //edit this line like this
Intent intent = new Intent(Register.this,LoginPage.class);
startActivity(intent);
return 1;
} else {
appPreferences.edit().putInt("app_first_time",
appCurrentBuildVersion).apply();
if (appLastBuildVersion == 0) {
Toast.makeText(getApplicationContext(), "First time", Toast.LENGTH_SHORT).show();
return 0; //es la primera vez
} else {
return 2; //es una versión nueva
}
}
}
}

you are depending on SharedPreferences as well as on clicked variable, you can depend on SharePreferences but not on variable because on each run you are setting clicked value to false.
1) Save current version in preference when button is clicked
appPreferences.edit().putInt("app_first_time",
appCurrentBuildVersion).apply();
2) save clicked value in preference when button is clicked
appPreferences.edit().putBoolean("clicked",
true).apply();
Now inside your appGetFirstTimeRun() fetch the value of version and clicked from SharedPreferences
int appLastBuildVersion = appPreferences.getInt("app_first_time", 0);
boolean clicked = appPreferences.getBoolean("clicked", false);

You also need to change the shared preferences value on click of save button. Then only next time when you open the app appGetFirstTimeRun method will load the Login page.
In you btnSave click listener where you are starting intent for activity just before startActivity add this code
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
appPreferences.edit().putInt("app_first_time",
appCurrentBuildVersion).apply();

in start of onCreate(); method, call checkStages();
in end of buttonSave.onClick() method, call Prefs.putStage(this, 1); followed by checkStages();
/*Prefs.getStage(this) default value is 0*/
public void checkStages() {
switch(Prefs.getStage(this)) {
case 1: //Login Page
startActivity(new Intent(this, LoginPage.class));
finish();
break;
default:
break;
}
}
This is the sample Android Application Template I use, to write any of my Android App.
You can get the Prefs class from this project

add this code to your splash screen
SharedPreferences wmbPreference = PreferenceManager.getDefaultSharedPreferences(context);
boolean isFirstRun = wmbPreference.getBoolean("FIRSTRUN", false);
if (!isFirstRun) {
startActivity(new Intent(context,RegirstorActivity.class));
}else{
startActivity(new Intent(context,LoginActivty.class));
}
so basically it will decide Is it first time (user registered) or not, after registration update the SharedPreferences

your are using click variable to identify if button is clicked or not but when you exist from the app and again then click value reset to false so instead of saving value in click variable you can use shared preference to save value true or false on button click and get value from shared preference to check
on click of save button
appPreferences.edit().putInt("app_second_time",
appCurrentBuildVersion).apply();

Try using following custom getter and setter method.
private static SharedPreferences getInstance(Context context) {
context.getSharedPreferences("MY_APP", Context.MODE_PRIVATE);
return sharedPreferences;
}
public boolean getAppStatus(Context context) {
return getInstance(context).getString("FIRST_TIME", false);
}
public void setAppStatus(Context context, boolean status) {
getInstance(context).edit().putString("FIRST_TIME", status).commit();
}
Now, When for the first time when you call getAppStatus() or in case where user haven't clicked save button even once. It will return false. You can update the value of "FIRST_TIME" variable when the user clicks on save button to true. Thus validating, whether user has interacted with register page or not.
#Override
public void onClick(View v) {
if(v.getId()==R.id.save_button)
setAppStatus(context,true);
}

I think this may be the answer. on your code clicked boolean variable is not stored on shared preferences but you are checking condition inside appGetFirstTimeRun() (button may not be clicked at second launch, but your condition needs to be true) so change your code by
Adding this line appPreferences.edit().putBoolean("first_run", true).apply();on buttonSave clicklistener and then add this line clicked = appPreferences.getBoolean("first_run", false);on appGetFirstTimeRun() function
and the complete code would be.
appGetFirstTimeRun();
boolean clicked=false;
buttonSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
appPreferences = appPreferences.edit().putBoolean("first_run",
true).apply(); //***Add this ****
appPreferences.edit().putInt("app_second_time",
appCurrentBuildVersion).apply();
String name = editTextName.getText().toString();
String pass = editTextPassword.getText().toString();
String confirm = editTextConfirm.getText().toString();
if ((editTextName.getText().toString().trim().length() == 0) || (editTextPassword.getText().toString().trim().length() == 0) || (editTextConfirm.getText().toString().trim().length() == 0)) {
Toast.makeText(getApplicationContext(), "Field cannot be null", Toast.LENGTH_LONG).show();
}
else
{
insertData(name, pass, imageUri); // insert to SQLite
Intent intent = new Intent(MainActivity.this, AddMonthlyExpenses.class);
intent.putExtra("name", name);
startActivity(intent);
}
}
});
private int appGetFirstTimeRun() {
//Check if App Start First Time
SharedPreferences appPreferences = getSharedPreferences("MyAPP", 0);
int appCurrentBuildVersion = BuildConfig.VERSION_CODE;
int appLastBuildVersion = appPreferences.getInt("app_first_time", 0);
clicked = appPreferences.getBoolean("first_run", false); //*** Add this ***
if (appLastBuildVersion == appCurrentBuildVersion && clicked) {
Intent intent = new Intent(MainActivity.this,LoginPage.class);
startActivity(intent);
return 1;
} else {
appPreferences.edit().putInt("app_first_time",
appCurrentBuildVersion).apply();
if (appLastBuildVersion == 0) {
Toast.makeText(getApplicationContext(), "First time", Toast.LENGTH_SHORT).show();
return 0; //es la primera vez
} else {
return 2; //es una versión nueva
}
}
}

//Use shared preference to save.
SharedPreferences preferedName=getSharedPreferences("firstrun", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = preferedName.edit();
editor.putboolean("firstrun",value);
editor.apply();
editor.commit();
//and to retrive.
SharedPreferences preferedName=getSharedPreferences("firstrun", Activity.MODE_PRIVATE);
boolean rstate =preferedName.getString("firstrun",false);
check if "rstste" is false show register page else show the login page.

Shared Preference values

I want to use the value of shared preferences from one activity to another activity, like if my pin from pin_activity is set on, the pattern from another activity should be disabled, and show the Toast that "PinService is ON, You can't Make PatternService ON" and vice versa. i am not getting how to use shared preference values. Please help me out in doing this
here is my code for both activities.
pin_activity.java
s2 = (Switch) findViewById(R.id.switch2);
spref = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
s2.setChecked(spref.getBoolean("SwitchButton", false));
s2.setOnClickListener(new ToggleButton.OnClickListener() {
public void onClick(View v) {
SharedPreferences.Editor editor = spref.edit();
editor.putBoolean("SwitchButton", s2.isChecked());
// editor.putString("switch_state", "value");
//switch_state=editor.putBoolean("SwitchButton", s2.isChecked());
editor.commit();
// Toast.makeText(getApplicationContext(), "Switch is ON", Toast.LENGTH_SHORT).show();
}
});
Pattern_activity.java
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
s1.setChecked(sharedPreferences.getBoolean("toggleButton", false));
switch1= sharedPreferences.getBoolean("editor",s1.isChecked() );
if (switch1== true)
{
s1.setEnabled(false);
Toast.makeText(getApplicationContext(), "PinService is ON, You can't Make PatternService ON", Toast.LENGTH_SHORT).show();
}
else
{
s1.setEnabled(true);
}
s1.setOnClickListener(new ToggleButton.OnClickListener() {
public void onClick(View v) {
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor editor = sharedPreferences.edit();
//switch1= sharedPreferences.getString("switch_state", null);
editor.commit();
// Toast.makeText(getApplicationContext(), "Switch is ON", Toast.LENGTH_SHORT).show();
}
});

You need to use the same key for your setting.
In your example you use "SwitchButton" to read/write the state of the switch in pin_activity and "editor" to read (supposedly) that same value. Which cannot work.
So extract a key string to a constant like public static String PIN_STATE = "PIN_STATE";.
in pin_activity:
s2 = (Switch) findViewById(R.id.switch2);
spref = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
s2.setChecked(spref.getBoolean(PIN_STATE, false));
s2.setOnClickListener(new ToggleButton.OnClickListener() {
public void onClick(View v) {
SharedPreferences.Editor editor = spref.edit();
editor.putBoolean(PIN_STATE, s2.isChecked());
// editor.putString("switch_state", "value");
//switch_state=editor.putBoolean(PIN_STATE, s2.isChecked());
editor.commit();
// Toast.makeText(getApplicationContext(), "Switch is ON", Toast.LENGTH_SHORT).show();
}
});
in Pattern_activity:
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
s1.setChecked(sharedPreferences.getBoolean("toggleButton", false));
switch1= sharedPreferences.getBoolean(PIN_STATE, s1.isChecked() );
if (switch1== true)
{
s1.setEnabled(false);
Toast.makeText(getApplicationContext(), "PinService is ON, You can't Make PatternService ON", Toast.LENGTH_SHORT).show();
}
else
{
s1.setEnabled(true);
}
And from that on you probably need to do something similar for PATTERN_STATE and in general straighten out you button states, as they seem a bit jumbled.

how to save toggle button state to database and if user edits then edited state should be saved to database in android

how to save toggle button state to database and if user edits then edited state should be saved to database in android.the following is my code it is working fine.but the problem is that when user edits to on it is in on state and green light displays on toggle button. and then user performs the required actions.when user again comes back to edit again it displays on only but no green light is visible.so it looks bad so please help me and following is my code.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_layout);
edittext=(EditText)findViewById(R.id.device_text);
light=(ToggleButton)findViewById(R.id.light);
alarm=(ToggleButton)findViewById(R.id.alarm);
db = new DataBaseAdapter(this);
Intent i = getIntent();
if(i.hasExtra("Dname"))
val = i.getStringExtra("Dname");
if(i.hasExtra("Dlight"))
slight=i.getStringExtra("Dlight");
blight=Boolean.valueOf(slight);
if(i.hasExtra("Dalarm"))
salarm=i.getStringExtra("Dalarm");
balarm=Boolean.valueOf(balarm);
if(i.hasExtra("Daddress"))
pos=i.getStringExtra("Daddress");
db.open();
db.insertData(pos,val,slight,salarm);
c = db.getData();
edittext.setText(val);
light.setText(slight);
// light.setChecked(blight);
alarm.setText(salarm);
//alarm.setChecked(balarm);
db.close();
}
#Override
public void onBackPressed(){
db.open();
c=db.getData();
if (c.moveToFirst()) {
do {
String strSQL = "UPDATE DeviceDetails SET devicename ='"+ edittext.getText().toString() +"' WHERE uuid = '"+c.getString(c.getColumnIndex("uuid"))+"'" ;
db.select(strSQL);
slight=light.getText().toString();
salarm=alarm.getText().toString();
if(pos.equalsIgnoreCase(c.getString(c.getColumnIndex("uuid"))))
{
db.updateData(pos, edittext.getText().toString(),slight,salarm);
}
Intent intent=new Intent();
intent.putExtra("Dname", edittext.getText().toString());
intent.putExtra("Daddress",pos);
intent.putExtra("Dlight", slight);
intent.putExtra("Dalarm", salarm);
setResult(RESULT_OK, intent);
finish();
} while (c.moveToNext());
}
db.close();
super.onBackPressed();
}
}

You can use SharedPrefernce for saving the state of toggle button.
sharedpreferences = context.getSharedPreferences("Toggle_pref", Context.MODE_PRIVATE);
Editor editor = sharedpreferences.edit();
editor.putInt("button_state", "state");
editor.commit();

This is code for Toogle Button with saved state..
private SharedPreferences spref;
private ToggleButton tb;
private boolean on;
spref = getSharedPreferences("APP", MODE_PRIVATE);
tb = (ToggleButton) findViewById(R.id.toogleButton);
on = spref.getBoolean("On", true); //default is true
if (on)
{
tb.setChecked(true);
} else
{
tb.setChecked(false);
}
tb.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if (tb.isChecked()) {
//Toast.makeText(MainActivity.this, "On : Notification will be Enabled", Toast.LENGTH_SHORT).show();
SharedPreferences.Editor editor = spref.edit();
editor.putBoolean("On", true); // value to store
editor.commit();
} else {
// Toast.makeText(MainActivity.this, "Off : Notification will be Disabled", Toast.LENGTH_SHORT).show();
SharedPreferences.Editor editor =spref.edit();
editor.putBoolean("On", false); // value to store
editor.commit();
}
}
});

in the following way i done and my problem solved.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_layout);
edittext=(EditText)findViewById(R.id.device_text);
light=(ToggleButton)findViewById(R.id.light);
alarm=(ToggleButton)findViewById(R.id.alarm);
db = new DataBaseAdapter(this);
Intent i = getIntent();
if(i.hasExtra("Dname"))
val = i.getStringExtra("Dname");
if(i.hasExtra("Dlight"))
slight=i.getStringExtra("Dlight");
blight=Boolean.valueOf(slight);
if(i.hasExtra("Dalarm"))
salarm=i.getStringExtra("Dalarm");
balarm=Boolean.valueOf(balarm);
Log.v("___EDIT CLASS____________", "__LIGHT TEXT_____________"+slight);
Log.v("_____EDIT CLASS_____________", "___ALARM TEXT____________"+salarm);
Log.v("___EDIT CLASS____________", "__LIGHT boolean_____________"+blight);
Log.v("_____EDIT CLASS_____________", "___ALARM boolean____________"+balarm);
// edittext.setText(val);
if(i.hasExtra("Daddress"))
pos=i.getStringExtra("Daddress");
Log.v("___________edittext", "_______________"+edittext.getText());
Log.v("__________address", "_______________"+pos);
db.open();
db.insertData(pos,val,slight,salarm);
c = db.getData();
edittext.setText(val);
light.setText(slight);
// light.setChecked(blight);
alarm.setText(salarm);
//alarm.setChecked(balarm);
if(slight.equalsIgnoreCase("on"))
{
light.setChecked(true);
}
else
{
light.setChecked(false);
}
if(salarm.equalsIgnoreCase("on"))
{
alarm.setChecked(true);
}
else
{
alarm.setChecked(false);
}
db.close();
}
#Override
