不知道怎么在drawable里建item的自行百度

先看目录结构：

        }
    }
}

HomePageFragment 其中的一个界面 首页

package com.example.matsonga.tabbaractivity;

import android.content.Context;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class HomePageFragment extends BasePageTitleFragent {

    @Override
    protected View initView() {
        setTitleIcon("首页",true); //设置第一个首页不显示标题
        View homeFragment = View.inflate(getContext(), R.layout.fg_homepage, null);
        return homeFragment ;
    }

    @Override
    protected void initData() {

    }
}

homepage的drawabe 其他界面和他一样 改一下图片名字就行

屏幕快照 2019-05-27 下午11.55.10.png

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/tab_assistant_gray" android:state_selected="true" />
    <item android:drawable="@drawable/tab_assistant_light" />
</selector>

homepage的XML 其他界面和他一样 内容自定义

屏幕快照 2019-05-27 下午11.56.28.png

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

</LinearLayout>
