Drawer layout

MainActivity

这是 MAinActivity.java：

package com.neuron.hw_0;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;

import androidx.appcompat.app.ActionBarDrawerToggle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.view.GravityCompat;
import androidx.drawerlayout.widget.DrawerLayout;

import com.google.android.material.navigation.NavigationView;

public class MainActivity extends AppCompatActivity {
    private DrawerLayout drawer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        androidx.appcompat.widget.Toolbar toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);

        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar,
                R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.addDrawerListener(toggle);
        toggle.syncState();
    }
    @Override
    public void onBackPressed() {
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    public void opbr(View view){

        //Get url from tag
        String url = (String)view.getTag();

        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);

        //pass the url to intent data
        intent.setData(Uri.parse("https://www.facebook.com/AadeshGurav99"));

        startActivity(intent);
    }

    public void opbr1(View view){

        //Get url from tag
        String url = (String)view.getTag();

        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);

        //pass the url to intent data
        intent.setData(Uri.parse("https://github.com/Aadesh9985?tab=repositories"));

        startActivity(intent);
    }

}

这是抽屉菜单：

        <item
