全屏活动向导活动。 如何在与设备交互时停止显示操作栏?

当我使用全屏活动向导创建活动时,它会创建一个全屏活动,但每当我点击屏幕上的任何位置时,操作栏会显示几秒钟。 我怎么能阻止它这样做?

FullScreenActivity.java的完整代码

/** * An example full-screen activity that shows and hides the system UI (ie * status bar and navigation/system bar) with user interaction. * * @see SystemUiHider */ public class FullscreenActivity extends Activity { /** * Whether or not the system UI should be auto-hidden after * {@link #AUTO_HIDE_DELAY_MILLIS} milliseconds. */ private static final boolean AUTO_HIDE = true; /** * If {@link #AUTO_HIDE} is set, the number of milliseconds to wait after * user interaction before hiding the system UI. */ private static final int AUTO_HIDE_DELAY_MILLIS = 3000; /** * If set, will toggle the system UI visibility upon interaction. Otherwise, * will show the system UI visibility upon interaction. */ private static final boolean TOGGLE_ON_CLICK = true; /** * The flags to pass to {@link SystemUiHider#getInstance}. */ private static final int HIDER_FLAGS = SystemUiHider.FLAG_HIDE_NAVIGATION; /** * The instance of the {@link SystemUiHider} for this activity. */ private SystemUiHider mSystemUiHider; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_fullscreen); final View controlsView = findViewById(R.id.fullscreen_content_controls); final View contentView = findViewById(R.id.fullscreen_content); // Set up an instance of SystemUiHider to control the system UI for // this activity. mSystemUiHider = SystemUiHider.getInstance(this, contentView, HIDER_FLAGS); mSystemUiHider.setup(); mSystemUiHider .setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() { // Cached values. int mControlsHeight; int mShortAnimTime; @Override @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2) public void onVisibilityChange(boolean visible) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) { // If the ViewPropertyAnimator API is available // (Honeycomb MR2 and later), use it to animate the // in-layout UI controls at the bottom of the // screen. if (mControlsHeight == 0) { mControlsHeight = controlsView.getHeight(); } if (mShortAnimTime == 0) { mShortAnimTime = getResources().getInteger( android.R.integer.config_shortAnimTime); } controlsView .animate() .translationY(visible ? 0 : mControlsHeight) .setDuration(mShortAnimTime); } else { // If the ViewPropertyAnimator APIs aren't // available, simply show or hide the in-layout UI // controls. controlsView.setVisibility(visible ? View.VISIBLE : View.GONE); } if (visible && AUTO_HIDE) { // Schedule a hide(). delayedHide(AUTO_HIDE_DELAY_MILLIS); } } }); // Set up the user interaction to manually show or hide the system UI. contentView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (TOGGLE_ON_CLICK) { mSystemUiHider.toggle(); } else { mSystemUiHider.show(); } } }); // 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); } @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); // Trigger the initial hide() shortly after the activity has been // created, to briefly hint to the user that UI controls // are available. delayedHide(100); } /** * 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. */ View.OnTouchListener mDelayHideTouchListener = new View.OnTouchListener() { @Override public boolean onTouch(View view, MotionEvent motionEvent) { if (AUTO_HIDE) { delayedHide(AUTO_HIDE_DELAY_MILLIS); } return false; } }; Handler mHideHandler = new Handler(); Runnable mHideRunnable = new Runnable() { @Override public void run() { mSystemUiHider.hide(); } }; /** * Schedules a call to hide() in [delay] milliseconds, canceling any * previously scheduled calls. */ private void delayedHide(int delayMillis) { mHideHandler.removeCallbacks(mHideRunnable); mHideHandler.postDelayed(mHideRunnable, delayMillis); } } 

如果我理解正确,你只想隐藏动作栏?

如果是,请更改此行(将flag_hide_navigation更改为0)。

 private static final int HIDER_FLAGS = 0;// SystemUiHider.FLAG_HIDE_NAVIGATION; 

并将其添加到onCreate调用:

 protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_ACTION_BAR); //new getActionBar().hide(); //new getWindow().setFlags( WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_fullscreen); 

之后,如果您想要显示操作栏,只需从活动中的任何位置进行呼叫:

 getActionBar().show(); 

我试着用0代替3000

 private static final int AUTO_HIDE_DELAY_MILLIS = 3000; 

但它变得太迟了……所以,在androidmanifest.xml添加更改的技巧

 android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 

AndroidManifest.xml underApplication

这对我有用。 尽管导航器未完全移除,但用户无需花费太多时间进行交互,而且按钮图标也是小点。 此外,这减少了整个屏幕全屏所需的代码量。

 SystemUiHider hider = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //go full screen with no title this.requestWindowFeature(Window.FEATURE_PROGRESS); //show progress on loadup this.requestWindowFeature(Window.FEATURE_NO_TITLE); //hide the title bar this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); //go fullscreen setContentView(R.layout.activity_main); //hide the navigation controls final RelativeLayout mainLayout = (RelativeLayout)this.findViewById(R.id.mainLayout); hider = SystemUiHider.getInstance(this, mainLayout, SystemUiHider.FLAG_HIDE_NAVIGATION); hider.setup(); hider.setOnVisibilityChangeListener(new SystemUiHider.OnVisibilityChangeListener() { @Override @TargetApi(Build.VERSION_CODES.HONEYCOMB_MR2) public void onVisibilityChange(boolean visible) { if (visible) { //will make navigator into small dots hider.hide(); //must use delayed to force navigator to disappear completely final Handler mHideHandler = new Handler(); final Runnable mHideRunnable = new Runnable() { @Override public void run() { hider.hide(); } }; mHideHandler.removeCallbacks(mHideRunnable); mHideHandler.postDelayed(mHideRunnable, 1000); //min 1 sec to work } } }); hider.hide(); //do the rest of your onCreate stuff here } 

我仔细研究了代码并在没有物理导航按钮的Android 4.2设备上启动了活动。 默认配置尽可能为全屏。 它隐藏状态栏操作栏导航栏 。 那么,如果不是在屏幕上的任何地方点击,用户将如何退出您的活动? 其他任何东西都会受到非常严格的限制和糟糕的可用性。 我认为这就是为什么不能操纵这种行为的原因。

您可以做的是更改SystemUiHider ,使其隐藏状态栏和操作栏,但不会隐藏导航栏。 它反而将导航栏变为三个淡点,请参见下面的屏幕截图。

变暗的导航栏

必须有更好的方法来实现这一目标,但以下工作。 在SystemUiHiderHoneycomb()构造函数的末尾注释这些行:

 if ((mFlags & FLAG_HIDE_NAVIGATION) != 0) { // If the client requested hiding navigation, add relevant flags. mShowFlags |= View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION; mHideFlags |= View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION; mTestFlags = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION; } 

然后,活动将全屏显示用户交互,您可以在特定事件中toggle() 。 当然,您仍然需要从原始答案进行更改以禁用单击行为。


原始答案:

我想你必须评论这部分:

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

在api19中我们可以使用:

 getWindow().getDecorView() .setSystemUiVisibility(View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION); 

隐藏导航栏和状态栏

将活动主题更改为没有操作栏。 最好是inheritance动作栏Sherlock活动并删除动作栏

虽然发布答案为时已晚,但据我所知,问题是因为我正在使用Android Studio提供的全屏活动模板,我认为这个问题的答案是禁用动作栏,用户与UI交互,这可以通过在contentView上禁用OnClickListener来实现

 contentView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (TOGGLE_ON_CLICK) { mSystemUiHider.toggle(); } else { mSystemUiHider.show(); } } }); 

即注释掉onClick方法实现。

只是评论出来

 if (TOGGLE_ON_CLICK) { mSystemUiHider.toggle(); } else { mSystemUiHider.show(); } 

默认情况下,状态为Off。 切换发生是因为还添加了一个切换屏幕的onclick监听器。 您可以简单地添加它并删除代码段。

最新代码是//设置用户交互以手动显示或隐藏系统UI。

 mContentView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // toggle(); } 

我简单地评论了toggle()和瞧
