有一些简单的 docker-compose.yml 文件配置，但我不知道为什么我不能使用pgadmin4@pgadmin.org作为电子邮件和admin作为密码登录 pgAdmin。是否需要更多配置或者我使用了错误的凭据？

version: "3.7"

services:
    db:
        image: postgres:13.1
        restart: unless-stopped
        env_file:
            - ./.env
        ports:
            - 5432:5432
        volumes:
            - db-data:/var/lib/postgresql/data
            - ./init-db.sh:/docker-entrypoint-initdb.d/init-database.sh
        networks:
            - appNetwork

    pgAdmin:
        container_name: pgAdmin
        # restart: unless-stopped
        image: dpage/pgadmin4:4.29
        environment:
            PGADMIN_DEFAULT_EMAIL: ${PGADMIN_DEFAULT_EMAIL:-pgadmin4@pgadmin.org}
            PGADMIN_DEFAULT_PASSWORD: ${PGADMIN_DEFAULT_PASSWORD:-admin}
            PGADMIN_LISTEN_PORT: 5050
        volumes:
            - pgadmin:/root/.pgadmin
        ports:
            - "5050:5050"
        depends_on:
            -   db
        networks:

在导航抽屉我想要两个功能:导入和导出我的数据库.听起来很简单,但在妈妈看来它不起作用.带有import元素和导出元素的导航抽屉列表是不可点击的,为什么会这样？

MainActivity.java

public class MainActivity extends Activity implements OnClickListener {

        private DrawerLayout mDrawerLayout;
        private ListView mDrawerList;
        private ActionBarDrawerToggle mDrawerToggle;

        // nav drawer title
        private CharSequence mDrawerTitle;

        // used to store app title
        private CharSequence mTitle;

        // slide menu items
        private String[] navMenuTitles;
//      private TypedArray navMenuIcons;

        private ArrayList<NavDrawerItem> navDrawerItems;
        private NavDrawerListAdapter adapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        try {
            tap_on_plus = (ImageView) findViewById(R.id.imageNewNote);
            Contact_listview = (ListView) findViewById(R.id.listView1);
            findViewById(R.id.button1).setOnClickListener(this);
