在Android上关闭键盘后返回沉浸式模式

我将沉浸式模式添加到我的应用程序中。代码如下：

 @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），导航栏将保持显示状态，我需要减少/重新打开应用程序以恢复沉浸式模式

关闭键盘后如何返回沉浸式模式

编辑：这是一个Cordova应用程序

此主题：涵盖类似的问题

这里提出的“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，告诉我如何解决这个问题，使事情保持一致：

简而言之：我将“延迟处理程序”与以下内容结合起来：

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) {}
}

这是你的答案

您需要在背压上重新启用浸入模式。这是那篇文章的代码

public class EditTextBackEvent extends EditText {

    private EditTextImeBackListener mOnImeBack;

    public EditTextBackEvent(Context context) {
        super(context);
    }

    public EditTextBackEvent(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public EditTextBackEvent(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onKeyPreIme(int keyCode, KeyEvent event) {
       if (event.getKeyCode() == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) {
            if (mOnImeBack != null) mOnImeBack.onImeBack(this, this.getText().toString());
        }
        return super.dispatchKeyEvent(event);
    }

    public void setOnEditTextImeBackListener(EditTextImeBackListener listener) {
        mOnImeBack = listener;
    }

    public interface EditTextImeBackListener {
       public abstract void onImeBack(EditTextBackEvent ctrl, String text);
    }

}

试试看。我已经搜索了3个多小时，这个解决方案效果很好。我希望它会有用。

这不是最好的解决方案，而是最简单、最适合我的解决方案

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);

我使用处理程序来检测用户的不活动性，并在此后隐藏系统ui。它会自动检测用户是否未在屏幕上交互，然后在5秒后自动隐藏系统UI

//Declare handler
private var timeoutHandler: Handler? = null
private var interactionTimeoutRunnable: Runnable? = null

在onCreate（）中

处理焦点更改的方法

    override fun onWindowFocusChanged(hasFocus: Boolean) {
        super.onWindowFocusChanged(hasFocus)
        if (hasFocus) hideSystemUI()
    }

隐藏系统用户界面

    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
}

你找到解决这个问题的方法了吗？没有，我没有：/。您有解决方案吗？它正在工作，但当键盘处于活动状态时，我无法在页面上滚动：/4全屏主题会在软键盘可见时（在4.4中）阻止滚动视图滚动。选择一个在manifest.xml中不是全屏的主题，例如：android:theme=“@android:style/theme.DeviceDefault.Light.NoActionBar”我使用@Victor Laskin的解决方案解决了这个问题。但现在我无法滚动页面查看键盘后面的内容。默认情况下，系统会猜测您希望调整活动的平移还是调整大小。我猜它是在使用调节盘。在上述活动的清单中添加以下

android:windowSoftInputMode=“adjustResize”
