开发中遇到的问题, Mark下

1.修改PreferenceFragment的ScrollBar样式

PreferenceFragment并没有提供相关接口,因此想要修改的话,需要重新写layout

package com.android.abc;

import android.content.Context;
import android.os.Bundle;
import android.preference.PreferenceFragment;
import android.support.annotation.Nullable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

import com.example.my.demo.R;

import java.util.jar.Attributes;

public class CustomPreferenceFragment extends PreferenceFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.custom_preference_list_fragment, container, false);
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.demo_preference);
    }

}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container_material"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent">

    <FrameLayout
        android:id="@android:id/list_container"
        android:layout_height="0px"
        android:layout_weight="1"
        android:layout_width="match_parent" >

        <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clipToPadding="false"
            android:divider="@null"
            android:dividerHeight="0dp"
            android:drawSelectorOnTop="false"
            android:fadeScrollbars="false"
            android:scrollbarAlwaysDrawVerticalTrack="true"
            android:scrollbarFadeDuration="0"
            android:scrollbarSize="1dp"
            android:scrollbarStyle="outsideOverlay"
            android:scrollbarThumbVertical="@drawable/scrollbar_vertical_thumb"
            android:scrollbarTrackVertical="@drawable/scrollbar_vertical_track"
            android:scrollbars="vertical" />

    </FrameLayout>

</LinearLayout>

scrollbar_vertical_thumb.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <size android:width="1dp" android:height="60dp" />
            <corners android:radius="2px" />
            <solid android:width="2px" android:color="#FF3098FA" />
        </shape>
    </item>
</selector>

scrollbar_vertical_track.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <corners android:radius="6px" />
            <solid android:width="6px" android:color="#FF2A3039" />
        </shape>
    </item>
</selector>

效果如下:
