Using Shared Preferences for High Score saving

Question

Hell I am trying to make highscore for my project but my code is only saving last value not highest value How can I store only highest value? here is my code .

This is saving process ->

            SharedPreferences prefs = getSharedPreferences(MY_PREFERENCES, Context.MODE_PRIVATE);
            SharedPreferences.Editor editor = prefs.edit();
            TextView outputView = (TextView)findViewById(R.id.textscore);
            CharSequence textData = outputView.getText();

            if (textData != null) {
               editor.putString(TEXT_DATA_KEY, textData.toString());
               editor.commit();
            } 

This is Reading process

  SharedPreferences prefs = getSharedPreferences(MY_PREFERENCES, Context.MODE_PRIVATE);

  String textData = prefs.getString(TEXT_DATA_KEY, "No Preferences!");


            TextView outputView = (TextView) findViewById(R.id.textread); 

Answer 1

You need to check the previously saved value to see which is highest else it you will just save the latest value, not the highest

E.g.

      if (textData != null) {
           int score = Integer.parseInt(textData.toString());

           if(score > prefs.getInt(TEXT_DATA_KEY, 0)) // Or get String, with parse Int.
           {
               //editor.putString(TEXT_DATA_KEY, textData.toString()); // Should be saved as int
               editor.putInt(TEXT_DATA_KEY, score);
               editor.commit();
           }
        }

You need to store a new value only if the existing value in shared preferences is lesser than the new value.

You don't seem to be having this value check in your code
