关闭Android键盘后返回沉浸式模式
关闭Android键盘后返回沉浸式模式
提问于 2014-05-04 12:20:49
我在我的应用程序中添加了沉浸式模式。以下是代码：
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus)
{
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}
}但是，如果我在键盘上键入并关闭它(通过单击屏幕上的后退按钮)，导航栏将保持显示，我需要减少/重新打开应用程序以恢复沉浸模式。
如何在关闭键盘后返回沉浸式模式？

之后，我使用处理程序来检测用户的不活动，并隐藏系统ui。它自动检测用户是否没有在屏幕上交互，然后在5秒后自动隐藏系统用户界面。
//Declare handler
private var timeoutHandler: Handler? = null
private var interactionTimeoutRunnable: Runnable? = null在onCreate()
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
. . .
//Initialise handler
timeoutHandler = Handler();
interactionTimeoutRunnable = Runnable {
// Handle Timeout stuffs here
hideSystemUI()
}
//start countdown
startHandler()
. . .处理焦点更改的方法
override fun onWindowFocusChanged(hasFocus: Boolean) {
super.onWindowFocusChanged(hasFocus)
if (hasFocus) hideSystemUI()
}隐藏系统Ui
private fun hideSystemUI() {
// Enables regular immersive mode.
// For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
// Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_IMMERSIVE
// Set the content to appear under the system bars so that the
// content doesn't resize when the system bars hide and show.
or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
// Hide the nav bar and status bar
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_FULLSCREEN)
}
// Shows the system bars by removing all the flags
// except for the ones that make the content appear under the system bars.
private fun showSystemUI() {
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
}
// reset handler on user interaction
override fun onUserInteraction() {
super.onUserInteraction()
resetHandler()
}
//restart countdown
fun resetHandler() {
timeoutHandler!!.removeCallbacks(interactionTimeoutRunnable);
timeoutHandler!!.postDelayed(interactionTimeoutRunnable, 5*1000); //for 10 second
}
// start countdown
fun startHandler() {
timeoutHandler!!.postDelayed(interactionTimeoutRunnable, 5*1000); //for 10 second

主题：Immersive mode navigation becomes sticky after volume press or minimise-restore涵盖了类似的问题。
建议的“延迟”解决方案应该适用于您的情况。
我偶然发现了同样的问题，当你在应用程序之间切换时，导航栏也不会隐藏。我写了一些指南，说明我是如何解决这个问题的：http://vitiy.info/small-guide-how-to-support-immersive-mode-under-android-4-4/
简而言之:我将“延迟处理程序”与以下内容结合在一起：
public void restoreTransparentBars()
{
if (isApplicationInImmersiveMode)
try {
Window w = activity.getWindow();
w.getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
);
w.getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
} catch (Exception e) {}

这不是最好的解决方案，而是最简单的挑战，并为我工作。
试试这个：
final Handler forceImmersive = new Handler();
Runnable runnable = new Runnable() {
@Override
public void run() {
// Enables regular immersive mode.
// For "lean back" mode, remove SYSTEM_UI_FLAG_IMMERSIVE.
// Or for "sticky immersive," replace it with SYSTEM_UI_FLAG_IMMERSIVE_STICKY
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(
View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
// Set the content to appear under the system bars so that the
// content doesn't resize when the system bars hide and show.
| View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
// Hide the nav bar and status bar
| View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
| View.SYSTEM_UI_FLAG_FULLSCREEN);
forceImmersive.postDelayed(this, 1000);
}
};
forceImmersive.postDelayed(runnable, 1000);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
