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

java 复制代码

package com.zx.tab;

import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.fragment.app.Fragment;

/**
 * 首页Fragment，用于展示和控制状态栏的显示与隐藏。
 */
public class HomeFragment extends Fragment {

    private static final String ARG_PARAM1 = "首页";
    private Button btn_hide_status_bar; // 控制隐藏状态栏的按钮
    private Button btn_show_status_bar; // 控制显示状态栏的按钮
    // 数据传递监听器接口
    public interface OnDataPassListener {
        void onHideStatusBar(String data); // 当隐藏状态栏时被调用
        void onShowStatusBar(String data); // 当显示状态栏时被调用
    }

    // 用于接收Activity传回的监听实例
    private OnDataPassListener mDataPassListener;

    // 创建HomeFragment实例的方法，用于传入参数
    public static HomeFragment newInstance(String param1) {
        HomeFragment fragment = new HomeFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        fragment.setArguments(args);
        return fragment;
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View contentView = inflater.inflate(R.layout.home, container, false);
        btn_hide_status_bar = contentView.findViewById(R.id.btn_hide_status_bar);
        btn_show_status_bar = contentView.findViewById(R.id.btn_show_status_bar);
        // 设置按钮点击事件
        btn_hide_status_bar.setOnClickListener(v -> {
            if (mDataPassListener != null) {
                mDataPassListener.onHideStatusBar("状态栏已隐藏");
            }
        });

        btn_show_status_bar.setOnClickListener(v -> {
            if (mDataPassListener != null) {
                mDataPassListener.onShowStatusBar("状态栏已显示");
            }
        });

        return contentView;
    }
    // 在Fragment与Activity建立关联时设置监听器
    @Override
    public void onAttach(@NonNull Context context) {
        super.onAttach(context);
        try {
            mDataPassListener = (OnDataPassListener) context;
        } catch (ClassCastException e) {
            throw new ClassCastException(context.toString() + " 必须实现 OnDataPassListener 接口");
        }
    }
}

布局

XML 复制代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_height="match_parent">
<!--  隐藏状态栏 显示状态栏-->
<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="隐藏状态栏"
    android:id="@+id/btn_hide_status_bar"/>
    <Button
        android:id="@+id/btn_show_status_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="显示状态栏"/>
</LinearLayout>

最后这里是Activity代码

java 复制代码

        }

    }

    //实现接口 隐藏状态栏
    public void onHideStatusBar(String data) {

        if (getSupportActionBar() != null) {

    }
