• 安卓在Fragment控制状态栏显示隐藏

    废话不多上效果

    隐藏

    显示

    核心代码

    首先是Framgrent

    1. package com.zx.tab;
    2.  
    3. import android.content.Context;
    4. import android.os.Bundle;
    5. import android.view.LayoutInflater;
    6. import android.view.View;
    7. import android.view.ViewGroup;
    8. import android.widget.Button;
    9.  
    10. import androidx.annotation.NonNull;
    11. import androidx.annotation.Nullable;
    12. import androidx.fragment.app.Fragment;
    13.  
    14. /**
    15.  * 首页Fragment，用于展示和控制状态栏的显示与隐藏。
    16.  */
    17. public class HomeFragment extends Fragment {
    18.  
    19.     private static final String ARG_PARAM1 = "首页";
    20.     private Button btn_hide_status_bar; // 控制隐藏状态栏的按钮
    21.     private Button btn_show_status_bar; // 控制显示状态栏的按钮
    22.     // 数据传递监听器接口
    23.     public interface OnDataPassListener {
    24.         void onHideStatusBar(String data); // 当隐藏状态栏时被调用
    25.         void onShowStatusBar(String data); // 当显示状态栏时被调用
    26.     }
    27.  
    28.     // 用于接收Activity传回的监听实例
    29.     private OnDataPassListener mDataPassListener;
    30.  
    31.     // 创建HomeFragment实例的方法，用于传入参数
    32.     public static HomeFragment newInstance(String param1) {
    33.         HomeFragment fragment = new HomeFragment();
    34.         Bundle args = new Bundle();
    35.         args.putString(ARG_PARAM1, param1);
    36.         fragment.setArguments(args);
    37.         return fragment;
    38.     }
    39.  
    40.     @Nullable
    41.     @Override
    42.     public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    43.         View contentView = inflater.inflate(R.layout.home, container, false);
    44.         btn_hide_status_bar = contentView.findViewById(R.id.btn_hide_status_bar);
    45.         btn_show_status_bar = contentView.findViewById(R.id.btn_show_status_bar);
    46.         // 设置按钮点击事件
    47.         btn_hide_status_bar.setOnClickListener(v -> {
    48.             if (mDataPassListener != null) {
    49.                 mDataPassListener.onHideStatusBar("状态栏已隐藏");
    50.             }
    51.         });
    52.  
    53.         btn_show_status_bar.setOnClickListener(v -> {
    54.             if (mDataPassListener != null) {
    55.                 mDataPassListener.onShowStatusBar("状态栏已显示");
    56.             }
    57.         });
    58.  
    59.         return contentView;
    60.     }
    61.     // 在Fragment与Activity建立关联时设置监听器
    62.     @Override
    63.     public void onAttach(@NonNull Context context) {
    64.         super.onAttach(context);
    65.         try {
    66.             mDataPassListener = (OnDataPassListener) context;
    67.         } catch (ClassCastException e) {
    68.             throw new ClassCastException(context.toString() + " 必须实现 OnDataPassListener 接口");
    69.         }
    70.     }
    71. }

    布局

    1. "1.0" encoding="utf-8"?>
    2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    3.     android:layout_width="match_parent"
    4.     android:orientation="vertical"
    5.     android:layout_height="match_parent">
    7. <Button
    8.     android:layout_width="match_parent"
    9.     android:layout_height="wrap_content"
    10.     android:text="隐藏状态栏"
    11.     android:id="@+id/btn_hide_status_bar"/>
    12.     <Button
    13.         android:id="@+id/btn_show_status_bar"
    14.         android:layout_width="match_parent"
    15.         android:layout_height="wrap_content"
    16.         android:text="显示状态栏"/>
    17. LinearLayout>

    布局效果
