How to apply InputFilter to EditTextPreferences?

I want to apply InputFilter to my EditTextPreferences...

Before I used the PreferenceActivity I had EditTexts with Filters like that:

            et1 = (EditText) findViewById(R.id.editText1);
            et2 = (EditText) findViewById(R.id.ETminsim);
            et3 = (EditText) findViewById(R.id.ETdelay);

            et1.setText(Integer.toString(PlotView.playlist_size), EditText.BufferType.EDITABLE);

            et2.setText(Integer.toString(conversorToInt(PlotView.min_sim)), EditText.BufferType.EDITABLE);
            et3.setText(Integer.toString(MusicService.getSeek()/1000), EditText.BufferType.EDITABLE);

            et1.setFilters(new InputFilter[]{ new InputFilterMinMax(1, 30)});
            et2.setFilters(new InputFilter[]{ new InputFilterMinMax(0, 100)});
            et3.setFilters(new InputFilter[]{ new InputFilterMinMax(0, 300)});

But how can I reference to the EditTexts of the EditTextPreference in order to set these Filters?

My new Code:

public void onCreate(Bundle bundle) {
                 super.onCreate(bundle);

                 getPreferenceManager().setSharedPreferencesName(Singleton.PREFS_NAME);
                 addPreferencesFromResource(R.xml.prefs);

                 //TODO set InputFilter
}
Solution

  • Konstantin had it mostly correct. Combine his answer with Sebastian's comment on his answer and you get

    EditText editText1 = ((EditTextPreference) findPreference(preference_1_key))
                         .getEditText();
editText1.setFilters(new InputFilter[]{ new InputFilterMinMax(1, 30) });
