Changed text at the runtime in textview but after relaunching application retrieving default data in textview in android

Question

I am using Shared Preferences to store data which is came from EditText and set preferences data back to TextView but when i reopen my application textview shows default value. How can set changed data to the TextView and data should not be lost after reopening application. I tried onSaveInstanceState() and onSaveInstanceState() but this works when orientation change of application.

Here in my code i store data into shared Preferences and getting that data back to the TextView PRESET_MESSAGE_ONE i am storing value of EditText.

public void customDialogOne() {
    mDialog = new Dialog(_con);
    mDialog.setContentView(R.layout.custom_dialog_message);
    mDialog.getWindow().setBackgroundDrawableResource(R.color.black);
    mDialog.setTitle("Edit Preset Message");

    btnPresetDialogCancel = (Button) mDialog
            .findViewById(R.id.btnPrDialogCancel);
    edtPresetDialogMessage = (EditText) mDialog
            .findViewById(R.id.edtPrDialogMessage);

    btnPresetDialogSave = (Button) mDialog
            .findViewById(R.id.btnPrDialogSave);
    btnPresetDialogSave.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            SharedPref.writeString(SharedPref.PRESET_MESSGE_ONE,
                    edtPresetDialogMessage.getText().toString());
            msgOne = SharedPref.readString(SharedPref.PRESET_MESSGE_ONE);
            tm.showToast(msgOne);
            tvFrPresetMsgOne.setText(msgOne);
            mDialog.dismiss();

        }
    });
    btnPresetDialogCancel.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            mDialog.dismiss();
        }
    });
    mDialog.show();
}

Please post your code. So i will provide you the solution of this problm — user2323471, May 05 '14 at 05:40
you need to put logic of resetting this value in the on resume of the relevant activity. onSaveInstanceState is only for orientation changes — Lena Bru, May 05 '14 at 05:41
Please let me know if any other way to achieve this task i am also looking for another solutions — Reena, May 05 '14 at 05:50
@PiYusHGuPtA can you please explain what should i check in onResume()? — Reena, May 05 '14 at 05:58
@Reena can you post `SharedPref.writeString()` and `SharedPref.readString()` method source code? — , May 05 '14 at 05:59
@Reena After save your data in `SharedPreference` and while you are retrieving data from you need to retrieve it in `onResume()` method. — Piyush, May 05 '14 at 06:00
@Vandana Please have look at above two methods which i wrote in SharedPref static class // for String value public static void writeString(String key, String value) { getEditor().putString(key, value).commit(); } public static String readString(String key) { return getPreferences().getString(key, null); } — Reena, May 05 '14 at 06:02
@Reena change this from `getPreferences().getString(key, null);` to `getPreferences().getString(key, "");` — Piyush, May 05 '14 at 06:15
@Piyush Thanks but solution is not that much helpful, i able to get data using getString(key,null), i am using this method to get and read data from server and its working, i think issue is at only TextView which is not able to set shared Preferences value after reopening the application. — Reena, May 05 '14 at 06:23
@Reena Yes it is. But you have to retrieve your data in `onResume()` method. means call `SharedPref.readString()` in `onResume()` method. — Piyush, May 05 '14 at 06:24

Have you commit your changes in the SharedPreference using SharedPref.commit(); ? Please check that one.

My issue has resolved my sequence was wrong to store value in shared Preferences, I used following code:

btnPresetDialogSave.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            tvFrPresetMsgOne.setText(edtPresetDialogMessage.getText()
                    .toString());
            SharedPref.writeString(SharedPref.PRESET_MESSGE_ONE,
                    edtPresetDialogMessage.getText().toString());

            msgOne = SharedPref.readString(SharedPref.PRESET_MESSGE_ONE);
            tvFrPresetMsgOne.setText(msgOne);
            mDialog.dismiss();

        }
    });

and read SharePreferences string in onResume method()

Changed text at the runtime in textview but after relaunching application retrieving default data in textview in android
