<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);    }};
