Android API 30后设置系统栏

从Android API 30开始，setSystemUIVisibilty就不被推荐使用了，而是使用WindowInsetsController，为了兼容低版本引入：

implementation "androidx.core:core:1.8.0"

1.系统栏

API

WindowInsetsControllerCompat controller = WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
// 设置状态栏反色
controller.setAppearanceLightStatusBars(true);
// 取消状态栏反色
controller.setAppearanceLightStatusBars(false);
// 设置导航栏反色
controller.setAppearanceLightNavigationBars(true);
// 取消导航栏反色
controller.setAppearanceLightNavigationBars(false);
// 隐藏状态栏
controller.hide(WindowInsetsCompat.Type.statusBars());
// 显示状态栏
controller.show(WindowInsetsCompat.Type.statusBars());
// 隐藏导航栏
controller.hide(WindowInsetsCompat.Type.navigationBars());
// 显示导航栏
controller.show(WindowInsetsCompat.Type.navigationBars());
// 同时隐藏状态栏和导航栏
controller.hide(WindowInsetsCompat.Type.systemBars());
// 同时隐藏状态栏和导航栏
controller.show(WindowInsetsCompat.Type.systemBars());

使用示例

private WindowInsetsControllerCompat controller;

/**
 * 是否显示状态栏
 */
private boolean isStatusBars = true;

public void setStatusBars(boolean isStatusBars) {
    this.isStatusBars = isStatusBars;
}

/**
 * 是否显示导航栏
 */
private boolean isNavigationBars = true;

public void setNavigationBars(boolean isNavigationBars) {
    this.isNavigationBars = isNavigationBars;
}

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        //设置状态栏透明
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        //false 表示沉浸，true表示不沉浸
        WindowCompat.setDecorFitsSystemWindows(getWindow(), false);

        controller = WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
        //是否开启反色
        controller.setAppearanceLightStatusBars(true);
        controller.setAppearanceLightNavigationBars(true);

        if (isStatusBars) {
            controller.show(WindowInsetsCompat.Type.statusBars());
        } else {
            controller.hide(WindowInsetsCompat.Type.statusBars());
        }
        if (isNavigationBars) {
            controller.show(WindowInsetsCompat.Type.navigationBars());
        } else {
            controller.hide(WindowInsetsCompat.Type.navigationBars());
        }
    }
}

/**
 * 显示系统栏
 */
public void showSystemUI() {
    if (isStatusBars) {
        controller.show(WindowInsetsCompat.Type.statusBars());
    }
    if (isNavigationBars) {
        controller.show(WindowInsetsCompat.Type.navigationBars());
    }
}

/**
 * 隐藏系统栏
 */
public void hideSystemUI() {
    // 同时隐藏状态栏和导航栏
    controller.hide(WindowInsetsCompat.Type.systemBars());
    //当系统栏在此模式下隐藏时，可以通过系统手势暂时显示它们
    controller.setSystemBarsBehavior(WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
}

2.键盘

code包还有键盘方面的引用

/**
 * 控制软键盘弹出和关闭
 */
public class InputMethodUtils {

    /**
     * 显示键盘
     */
    public static void showSoftKeyboard(WindowInsetsControllerCompat controller) {
        controller.show(WindowInsetsCompat.Type.ime());
    }

    /**
     * 显示键盘
     */
    public static void showSoftKeyboard(@NonNull Window window, @NonNull View view) {
        WindowInsetsControllerCompat controller = WindowCompat.getInsetsController(window, view);
        showSoftKeyboard(controller);
    }

    /**
     * 隐藏键盘
     */
    public static void hideSoftKeyboard(WindowInsetsControllerCompat controller) {
        controller.hide(WindowInsetsCompat.Type.ime());
    }

    /**
     * 隐藏键盘
     */
    public static void hideSoftKeyboard(@NonNull Window window, @NonNull View view) {
        WindowInsetsControllerCompat controller = WindowCompat.getInsetsController(window, view);
        hideSoftKeyboard(controller);
    }
}

在Activity'中使用

controller = WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
InputMethodUtils.hideSoftKeyboard(controller);

在dialog中使用

InputMethodUtils.hideSoftKeyboard(dialog.getWindow(), view);
