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

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@Overridepublic 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@Overridepublic 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 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-->
<Buttonandroid:layout_width="match_parent"android:layout_height="wrap_content"android:text="隐藏状态栏"android:id="@+id/btn_hide_status_bar"/><Buttonandroid:id="@+id/btn_show_status_bar"android:layout_width="match_parent"android:layout_height="wrap_content"android:text="显示状态栏"/>
</LinearLayout>

布局效果

最后这里是Activity代码

package com.zx.tab;import androidx.appcompat.app.AppCompatActivity;
import androidx.fragment.app.Fragment;
import androidx.viewpager2.widget.ViewPager2;import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.view.WindowInsets;
import android.view.WindowInsetsController;
import android.view.WindowManager;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;import java.util.ArrayList;
import java.util.List;public class MainActivity extends AppCompatActivity implements HomeFragment.OnDataPassListener{private final List<Fragment> fragmentList = new ArrayList<>();private final int[] tabIds = {R.id.ll_home,R.id.ll_mine};private final int[] iconIds = {R.id.im_home,R.id.im_mine};private final int[] textIds = {R.id.tv_home,R.id.tv_mine};private ViewPager2 viewPager2=null;private ImageView[] tabIcons=null;private TextView[] tabTexts=null;private ImageView imCurrent=null;private TextView tvCurrent=null;private LinearLayout ll_tabbar;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.initializeViews();this.initViewPager();this.changeTab(0);}private void initializeViews() {this.viewPager2 = findViewById(R.id.viewPager2);this.ll_tabbar=findViewById(R.id.ll_tabbar);LinearLayout[] tabLayouts = new LinearLayout[2];this.tabIcons = new ImageView[2];this. tabTexts = new TextView[2];for (int i = 0; i < 2; i++) {tabLayouts[i] = findViewById(tabIds[i]);tabIcons[i] = findViewById(iconIds[i]);tabTexts[i] = findViewById(textIds[i]);final int index = i;tabLayouts[i].setOnClickListener(view -> {viewPager2.setCurrentItem(index, false);changeTab(index);});}}private void initViewPager() {this. fragmentList.add(HomeFragment.newInstance(getString(R.string.tv_home)));this.fragmentList.add(MeFragment.newInstance(getString(R.string.tv_mine)));this.viewPager2.setAdapter(new FragmentAdapter(getSupportFragmentManager(), getLifecycle(), fragmentList));this. viewPager2.setUserInputEnabled(false);//是否滑动this.viewPager2.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {@Overridepublic void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {super.onPageScrolled(position, positionOffset, positionOffsetPixels);changeTab(position);}});}private void changeTab(int position) {if (imCurrent != null && tvCurrent != null) {this.imCurrent.setSelected(false);this.tvCurrent.setSelected(false);}this.imCurrent = tabIcons[position];this.tvCurrent = tabTexts[position];this.imCurrent.setSelected(true);this.tvCurrent.setSelected(true);}//实现接口 隐藏状态栏public void onHideStatusBar(String data) {this.ll_tabbar.setVisibility(View.GONE);// 隐藏顶部状态栏if (getSupportActionBar() != null) {getSupportActionBar().hide();}if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {// 使用WindowInsetsController的动画WindowInsetsController insetsController = getWindow().getInsetsController();if (insetsController != null) {insetsController.hide(WindowInsets.Type.statusBars());insetsController.setSystemBarsBehavior(WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);}} else {// 兼容旧版本，使用系统UI标志，并添加淡出动画getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);}}// 实现接口 显示状态栏public void onShowStatusBar(String data) {this.ll_tabbar.setVisibility(View.VISIBLE);// 显示顶部状态栏if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {WindowInsetsController insetsController = getWindow().getInsetsController();if (insetsController != null) {insetsController.show(WindowInsets.Type.statusBars());insetsController.setSystemBarsBehavior(WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);}} else {getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE);// 同样，这里可以考虑使用淡入动画来平滑显示状态栏}if (getSupportActionBar() != null) {getSupportActionBar().show();}// 如果状态栏颜色需要透明处理，可以在显示时设置（这取决于您的UI设计）// getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);// 或者使用setStatusBarColor设置特定颜色}}

下面是布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/white"android:orientation="vertical"><androidx.viewpager2.widget.ViewPager2android:id="@+id/viewPager2"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1" /><Viewandroid:layout_width="match_parent"android:layout_height="0.1dp"android:background="#f0f0f0" /><LinearLayoutandroid:id="@+id/ll_tabbar"android:layout_width="match_parent"android:layout_height="56dp"android:background="@color/white"android:orientation="horizontal"><LinearLayoutandroid:id="@+id/ll_home"android:layout_width="0dp"android:layout_height="match_parent"android:layout_weight="1"android:gravity="center"android:orientation="vertical"><ImageViewandroid:id="@+id/im_home"android:layout_width="24dp"android:layout_height="24dp"android:background="@drawable/tab_menu_home" /><TextViewandroid:id="@+id/tv_home"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="@string/tv_home"android:textColor="@drawable/tabar_title_text"android:textSize="12sp" /></LinearLayout><LinearLayoutandroid:id="@+id/ll_mine"android:layout_width="0dp"android:layout_height="56dp"android:layout_weight="1"android:gravity="center"android:orientation="vertical"><ImageViewandroid:id="@+id/im_mine"android:layout_width="24dp"android:layout_height="24dp"android:background="@drawable/tab_menu_mine" /><TextViewandroid:id="@+id/tv_mine"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="@string/tv_mine"android:textColor="@drawable/tabar_title_text"android:textSize="12sp" /></LinearLayout></LinearLayout></LinearLayout>
