I have xml file that defines some preference screens like the following example
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
android:key="root_preferencescreen">
<PreferenceScreen android:key="general_sett" android:title="general settings" />
....
<PreferenceScreen android:key="extras_sett" android:title="extras settings" />
</PreferenceScreen>
I would like to be able to increase the font size for the text of the preference screen , but because the within a preference screen there is no android:textsize tag , i have no idea how to accomplish that !
You can simply add android:textSize
inside your theme for preference screen:
e.g :
<style name="settingsTheme" parent="PreferenceThemeOverlay">
<item name="colorAccent">@color/color_ten</item>
<item name="android:background">@color/colorPrimaryLight</item>
<item name="android:windowAnimationStyle">@style/WindowAnimationTransition</item>
<item name="android:textColorPrimary">@color/colorTextBodyLight</item>
<item name="android:textColorSecondary">@color/colorTextCaptionLight</item>
<item name="android:textSize">14sp</item>
</style>
Your SettingsActivity
class :
public class SettingsActivity extends AppCompatActivity {
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
toolbar = (Toolbar)findViewById(R.id.toolbar_settings);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportFragmentManager().beginTransaction()
.replace(R.id.bodylayout, new PrefsFragment())
.commit();
}
@Override
protected void onPause() {
super.onPause();
}
}
PrefsFragment
class :
public class PrefsFragment extends PreferenceFragmentCompat implements SharedPreferences.OnSharedPreferenceChangeListener {
@Override
public void onCreatePreferences(Bundle bundle, String s) {
}
@Override
public void onCreate(Bundle savedInstanceState) {
final Context myContext = this.getActivity();
//set your theme
myContext.setTheme(R.theme.settingsTheme);
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settingspreference);
//do other stuffs
}
//.....
}
You can make a TextView
layout xml that looks something like this:
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/listSeparatorTextViewStyle"
android:textColor="@android:color/white"
android:id="@+android:id/title"
/>
and set the layout of your preference category in your preferences.xml
like this:
<PreferenceCategory
android:title="Category Title"
android:layout="@layout/pref_category"
/>
As long as the TextView
has the id @+android:id/title
you can make the layout look however you want. There is also a way to do this with styles that I haven't quite figured out.
