抽屉与Fragment的混合实现

依赖

implementation 'com.android.support:design:28.0.0'

抽屉用的是Sliding来实现的

效果图：

布局代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"

fragment继承类的代码：

package com.example.workday13;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Fragment_one extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_one,container,false);
    }
}

package com.example.workday13;

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Fragment_two extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_two,container,false);
    }
}

适配器代码：

package com.example.workday13;

import android.content.Context;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

import java.util.ArrayList;

public class MyViewPagerAdapter extends FragmentPagerAdapter {

    private ArrayList<Fragment> fragments;
    private Context context;
    private ArrayList<String> strings = new ArrayList<>();
    public MyViewPagerAdapter(FragmentManager fm,ArrayList<Fragment> fragments,Context context) {
        super(fm);
        this.fragments = fragments;
        this.context = context;
        strings.add("TAG1");
        strings.add("TAG2");
    }

    @Override
    public Fragment getItem(int i) {
        return fragments.get(i);
    }

    @Override
    public int getCount() {
        return fragments.size();
    }

    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return strings.get(position);
    }
}
