How would I save a textView in Shared Preferences?

Question

I want my app to save textView2 in shared preferences. This is the current shared preferences code I have that saves the state of a checkbox (checked/unchecked).

private boolean getFromSP(String key){
SharedPreferences bifrostPrefs = getApplicationContext().getSharedPreferences("bifrostPrefs", android.content.Context.MODE_PRIVATE);
return bifrostPrefs.getBoolean(key, false);
}
private void saveInSp(String key,boolean value){
SharedPreferences bifrostPrefs = getApplicationContext().getSharedPreferences("bifrostPrefs", android.content.Context.MODE_PRIVATE);
SharedPreferences.Editor editor = bifrostPrefs.edit();
editor.putBoolean(key, value);
editor.commit();
}

I never really worked with shared prefrences before so I don't really know how would I create a new shared prefrence to save my textview2.

Answer 1

You can't.

The SharedPreferences class provides a general framework that allows you to save and retrieve persistent key-value pairs of primitive data types. You can use SharedPreferences to save any primitive data: booleans, floats, ints, longs, and strings.

From doc Using Shared Preferences

Al-thought you can store value of TextView

//To get stored value
    private String getString(String key){
        SharedPreferences bifrostPrefs = getApplicationContext().getSharedPreferences("bifrostPrefs", android.content.Context.MODE_PRIVATE);
        return bifrostPrefs.getString(key, "");
    }

..

//To Save value
    private void saveString(String key, String value){
         SharedPreferences bifrostPrefs = getApplicationContext().getSharedPreferences("bifrostPrefs", android.content.Context.MODE_PRIVATE);
         SharedPreferences.Editor editor = bifrostPrefs.edit();
         editor.putString(key, value);
         editor.commit();
    }

How to use these methods

Put this code where you want to save TextVIew's value

//To save value of TextView
if (!TextUtils.isEmpty(aTextView.getText())) {
    saveString("aTextView", aTextView.getText().toString());
}

//To Read and show into TextVIew
aTextView.setText(getString("aTextView"));

You can easily save strings in Shared Preferences:
If you are unsure how to use Shared Preferences, this will be of great value to you.

As to TextViews, How about saving textView2.getText() ?
TextView.getText() obviously returns the text TextView is displaying. If you need other TextView properties, consult this.
