1添加主题样式

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>


<!-- 全屏 actionbar切换界面 -->
<style name="FullscreenTheme" parent="AppTheme">
    <item name="android:actionBarStyle">@style/FullscreenActionBarStyle</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:windowBackground">@null</item>
    <item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
    <item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
</style>

<!-- 全屏样式 欢迎界面-->
<style name="FullscreenActionBarStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:background">@color/black_overlay</item>
    <item name="android:windowFullscreen">true</item>
</style>

2. manifest 使用

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".common.welcome.SplashActivity"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/FullscreenActionBarStyle">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

3. activity 接切换

// Set up the user interaction to manually show or hide the system UI.
mContentView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        toggle();
    }
});

// Upon interacting with UI controls, delay any scheduled hide()
// operations to prevent the jarring behavior of controls going away
// while interacting with the UI.
findViewById(R.id.dummy_button).setOnTouchListener(mDelayHideTouchListener);

/**
 * Touch listener to use for in-layout UI controls to delay hiding the
 * system UI. This is to prevent the jarring behavior of controls going away
 * while interacting with activity UI.
 */
private final View.OnTouchListener mDelayHideTouchListener = new View.OnTouchListener() {
    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        if (AUTO_HIDE) {
            delayedHide(AUTO_HIDE_DELAY_MILLIS);
        }
        return false;
    }
};

private void toggle() {
    if (mVisible) {
        hide();
    } else {
        show();
    }
}

private void hide() {
    // Hide UI first
    ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.hide();
    }
    mControlsView.setVisibility(View.GONE);
    mVisible = false;

    // Schedule a runnable to remove the status and navigation bar after a delay
    mHideHandler.removeCallbacks(mShowPart2Runnable);
    mHideHandler.postDelayed(mHidePart2Runnable, UI_ANIMATION_DELAY);
}

@SuppressLint("InlinedApi")
private void show() {
    // Show the system bar
    mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
    mVisible = true;

    // Schedule a runnable to display UI elements after a delay
    mHideHandler.removeCallbacks(mHidePart2Runnable);
    mHideHandler.postDelayed(mShowPart2Runnable, UI_ANIMATION_DELAY);
}

private final Runnable mHidePart2Runnable = new Runnable() {
    @SuppressLint("InlinedApi")
    @Override
    public void run() {
        // Delayed removal of status and navigation bar

        // Note that some of these constants are new as of API 16 (Jelly Bean)
        // and API 19 (KitKat). It is safe to use them, as they are inlined
        // at compile-time and do nothing on earlier devices.
        mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
                | View.SYSTEM_UI_FLAG_FULLSCREEN
                | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
    }
};
private View mControlsView;
private final Runnable mShowPart2Runnable = new Runnable() {
    @Override
    public void run() {
        // Delayed display of UI elements
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.show();
        }
        mControlsView.setVisibility(View.VISIBLE);
    }
};
