android - 如何隐藏 fragment 中首选项之间的分隔线

Question

我想隐藏 fragment 中首选项之间的分隔符。代码如下:

1.SettingsActivity.java

public class SettingsActivity extends PreferenceActivity {
    super.onCreate(savedInstanceState);
    SettingsFragment settingsFragement = new SettingsFragment();
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.add(android.R.id.content, settingsFragement, "settings");
    transaction.commitAllowingStateLoss();
}

2.SettingsFragment.java

public class SettingsFragment extends PreferenceFragment{
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.settings);
    }
}

3.settings.xml

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory>
        <Preference 
             android:key="preference_a"
             android:title="preferenceA"/>
        <Preference 
             android:key="preference_b"
             android:title="preferenceB"/>
        <ListPreference 
             android:key="list_preference_c"
             android:title="list_preferenceC"/>
    </PreferenceCategory>
</PreferenceScreen>

首选项中有系统默认分隔符。我想隐藏分隔线。

如何隐藏分隔线？非常感谢。

谢谢大家的回答。但是，问题是我无法从 Activity 和 fragment 中获取 ListView 。

ListView list = (ListView) findViewById(android.R.id.list);

如果您正在使用 PreferenceFragmentCompat，它正在使用 Recycle View ，因此您必须使用此代码。这会自动隐藏分隔符

@Nullable
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {

   setDivider(new ColorDrawable(Color.TRANSPARENT));
   setDividerHeight(0);
}
