Question

I’m new at android. I have a little idea over sharedPreference. Some tutorials say to add preferences in a xml file, but I need to add preferences dynamically. So I done that from a java class(my settings page).

PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this);
CheckBoxPreference checkboxPref = new CheckBoxPreference(this);
        checkboxPref.setKey("1");
        checkboxPref.setTitle("SomeRandomStuff");
        root.addPreference(checkboxPref);

Now, Now I need to get title of all selected checkbox (true) from that settings page to show which option been selected.

How can I do that?
thank you.

Answer 1

you can use a regular checkbox and sharedPreferences. Just add it’s state like this

 // global variables
SharedPreferences data;
public static String filename = "prefs";

// setup the SharedPreferences in onCreate()
data = getSharedPreferences(filename, 0);

// set the SharedPreference based on checkbox state
@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
    switch (arg0) {
    case R.id.checkBox1:
        boolean checked = checkBox1.isChecked();
        SharedPreferences.Editor e = dataAddHS.edit();
        e.putBoolean("preferenceName", checked);
        e.commit();
    break;
    }

then when you need to pull the preference state, just do

boolean checked = data.getBoolean("preferenceName", false);

then you can use an if statement to see if checked is true or false, etc.
