Activity:

package com.example.work9_10;

import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {
//定义变量
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //获取资源ID
    drawer=findViewById(R.id.drawer);
    //添加侧滑布局
    if (savedInstanceState==null){
        getSupportFragmentManager().beginTransaction()
                //侧滑的id；要为侧滑添加的布局
                .add(R.id.fragment,new leftFragment())
                .commit();
    }
    initData();

}

private void initData() {
  				  //允许标题栏展示左边图标
 			   getSupportActionBar().setDisplayHomeAsUpEnabled(true);
   				 //图标toogle和侧滑联系
    toggle=new ActionBarDrawerToggle(this,drawer,R.string.open_drawer,R.string.close_drawer);
  			  drawer.addDrawerListener(toggle);
  		  toggle.syncState();
}

	  //点击图标，打开或关闭侧滑
public boolean onOptionsItemSelected(MenuItem item){
    if (toggle.onOptionsItemSelected(item)){
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

为侧滑添加的布局（只对布局加了背景）：

package com.example.work9_10;

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 leftFragment extends Fragment {
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.leftfragment,container,false);
return view;
}
}
