So I've been trying to create a settings activity using androidx.preference.PreferenceFragmentCompat and it's all working fine.
However for some reason there is some padding present on both the preference categories and the preferences themselves. I managed to get rid of the padding on the preferences by using app:iconSpaceReserved="false" but this doesn't seem to work on the categories.
I've tried all the various themes, PreferenceThemeOverlay.v14.Material etc but they don't seem to make a difference
Here is my code for everything!
SettingsActivity.java
import android.os.Bundle;
import androidx.appcompat.app.ActionBar;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
public class SettingsActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
Toolbar toolbar = findViewById(R.id.settings_toolbar);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
}
}
}
activity_settings.xml

<fragment

android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toBottomOf="@id/settings_toolbar" />
</androidx.constraintlayout.widget.ConstraintLayout>
SettingsTestFragment.java
import android.os.Bundle;
import androidx.preference.PreferenceFragmentCompat;
public class SettingsTestFragment extends PreferenceFragmentCompat {
@Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.preferences_test, rootKey);
}
}
preferences_test.xml
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="test" >
<Preference android:title="testPref" />
</PreferenceCategory>
</PreferenceScreen>
