                        case R.id.nav_help:
    //                        Pesan("Menu Help");
                            break;
                    }
    
                    DrawerLayout drawer = findViewById(R.id.drawer_layout);
                    drawer.closeDrawer(GravityCompat.START);
                    return true;
                }
    
                private void Pesan(String pesan) {
        
                    Toast.makeText(MainActivity.this, pesan, Toast.LENGTH_SHORT).show();
                }
            });
        }
    
        @Override
        public void onBackPressed() {
        
            DrawerLayout drawer = findViewById(R.id.drawer_layout);
            if (drawer.isDrawerOpen(GravityCompat.START)) {
        
                drawer.closeDrawer(GravityCompat.START);
            } else {
        
                super.onBackPressed();
            }
        }
    }

这个代码实现了以下功能：

1.  设置了一个工具栏（Toolbar），它是应用栏的一部分，用于显示应用的标题和操作按钮。
2.  初始化了底部导航栏（`AnimatedBottomBar`），在 `onCreate` 方法中选中了默认选项并加载了相应的碎片（`Fragment`）。
3.  底部导航栏的选择监听器在选项切换时加载不同的碎片。
4.  设置了抽屉式导航栏（`NavigationView`），允许用户通过滑动侧边栏来访问不同的菜单选项。
5.  处理了抽屉式导航栏中各菜单选项的点击事件。
6.  处理了后退按钮的行为，如果抽屉式导航栏打开，会关闭它，否则会执行默认的后退操作。

这段代码实现了一个具有底部导航栏和抽屉式导航栏的Android应用的主活动。不同的选项卡切换不同的碎片内容，而侧边栏菜单提供了额外的导航选项。

SplashActivity.java

package com.project.petApp;
    
    import android.content.Context;
    import android.content.Intent;
    import android.os.Bundle;
    import android.os.Handler;
    import android.widget.TextView;
    
    import androidx.appcompat.app.AppCompatActivity;
    
    import com.project.petApp.util.TypefaceUtil;
    
    public class SplashActivity extends AppCompatActivity {
        protected Handler mHandler=new Handler();
        protected TextView tv1,tv2;
        protected Context mContext= SplashActivity.this;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_splash);
    
            tv1=findViewById(R.id.text1);
            tv2=findViewById(R.id.text2);
    
    //        FontsUtils.setAppTypeface(mContext);
    
            TypefaceUtil tfUtil = new TypefaceUtil(mContext, "fonts/aa.ttf");
            tfUtil.setTypeface(tv1,false);
            tfUtil.setTypeface(tv2,false);
    //        TextView tv = findViewById(R.id.text1);
    //        Typeface typeface = Typeface.createFromAsset(mContext.getAssets(), "fonts/simkai.ttf");  // mContext为上下文
    //        tv.setTypeface(typeface );
    
            mHandler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    startActivity(new Intent(SplashActivity.this, MainActivity.class));
                }
            },4000);//2秒钟之后进入闪屏页
        }
    }

以下是一个Android应用的`SplashActivity`的代码，它用于在应用启动时显示一个闪屏屏幕，然后在一段时间后切换到主活动。下面是代码的详细解释：

*  代码开始定义了包名，并导入了Android应用所需的类和库，包括`Context`、`Intent`、`Handler`和`TextView`。还导入了一个自定义的实用工具类`TypefaceUtil`。

protected Handler mHandler = new Handler();
        protected TextView tv1, tv2;
        protected Context mContext = SplashActivity.this;

*  在这里，声明了实例变量，包括`Handler`、两个`TextView`小部件（`tv1`和`tv2`）以及一个`Context`对象（`mContext`）。`Handler`用于在指定的时间后发布一个延迟操作。

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

*  这是`onCreate`方法，当活动创建时会被调用。它将内容视图设置为在`R.layout.activity_splash`中定义的布局。这个布局可能包含了闪屏屏幕的可视元素。

tv1 = findViewById(R.id.text1);
            tv2 = findViewById(R.id.text2);

*  这些代码行通过它们的ID（`text1`和`text2`）在布局中找到两个`TextView`元素，并将它们分配给`tv1`和`tv2`变量。这些`TextView`小部件用于在闪屏屏幕上显示文本。

TypefaceUtil tfUtil = new TypefaceUtil(mContext, "fonts/aa.ttf");
            tfUtil.setTypeface(tv1, false);
            tfUtil.setTypeface(tv2, false);

*  在这里，创建了一个`TypefaceUtil`对象（`tfUtil`），这是一个自定义的实用程序类，用于将自定义字体应用于文本视图。它将来自"fonts/aa.ttf"文件的自定义字体设置给`tv1`和`tv2`。

mHandler.postDelayed(new Runnable() {
        
                @Override
                public void run() {
        
                    startActivity(new Intent(SplashActivity.this, MainActivity.class));
                }
            }, 4000); // 2秒延迟后开始主活动
        }
    }

*  最后，在`Handler`上发布一个带有4000毫秒（4秒）延迟的`Runnable`。在此延迟后，将执行`Runnable`中的`run`方法。在`run`方法内部，创建了一个`Intent`以启动`MainActivity`，然后调用`startActivity`以在显示闪屏屏幕4秒后切换到主活动。

这段代码演示了Android闪屏屏幕活动的典型结构，包括布局设置、字体自定义以及在延迟后切换到主活动。
