如何隐藏片段中首选项之间的分隔符

Question

我想隐藏片段中的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>

偏好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,问题是我无法从活动和片段中获取列表视图.

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

Answer 1

如果您使用的是PreferenceFragmentCompat,则它正在使用"回收"视图,因此您必须使用此代码.这会自动隐藏分隔线

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

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

Answer 2

这些解决方案对我不起作用.这是我做的PreferenceFragmentCompat:

@Override
public void setDivider(Drawable divider) {
    super.setDivider(new ColorDrawable(Color.TRANSPARENT));
}

@Override
public void setDividerHeight(int height) {
    super.setDividerHeight(0);
}

第一：如果使用xml中的listview

android:dividerHeight="0dp"在 xml 文件中的 listview 中设置，

第二：

ListView list = (ListView) findViewById(android.R.id.list);
list.setDivider(new ColorDrawable(Color.TRANSPARENT)); // or some other color int
list.setDividerHeight((int) getResources().getDisplayMetrics().density);
