Android 当键盘显示时,状态栏显示

Android 当键盘显示时,状态栏显示,android,android-layout,android-statusbar,Android,Android Layout,Android Statusbar,我的活动使用了CollasingToolbarLayout,我成功地删除了状态栏,执行以下操作: View decorView = getWindow().getDecorView(); // Hide the status bar. int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN; decorView.setSystemUiVisibility(uiOptions); 问题是,当软键盘弹出时,状态栏会再次出现,占用宝贵的空间 如何将其永久隐藏在活

我的活动使用了CollasingToolbarLayout,我成功地删除了状态栏,执行以下操作:

View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
问题是,当软键盘弹出时,
状态栏会再次出现,占用宝贵的空间

如何将其永久隐藏在
活动视图中

如果我将其设置为全屏,它可以工作,但我松开了
SOFT\u INPUT\u ADJUST\u RESIZE
参数。当出现
软键盘时,主窗口将滚动,而不是根据需要调整大小

该活动正在使用NoActionBar方案(在清单上声明)。

在样式活动样式中添加此行

<item name="android:windowFullscreen">true</item>

告诉我它是否有效。

需要注意的要点:-

1) 一旦清除了UI标志(例如,通过导航离开活动),如果要再次隐藏栏,应用程序需要重置它们。有关如何侦听UI可见性更改以便应用程序能够相应响应的讨论,请参阅更改

2) 设置UI标志的位置会有所不同。如果在活动的onCreate()方法中隐藏系统栏,并且用户按Home键,系统栏将重新出现。当用户重新打开活动时,不会调用onCreate(),因此系统栏将保持可见。如果希望系统UI更改在用户进出活动时保持不变,请在onResume()或onWindowFocusChanged()中设置UI标志

3) 方法setSystemMivibility()只有在从中调用它的视图可见时才有效

4) 离开视图导航会导致清除使用setSystemMivibility()设置的标志

您应该在创建时添加此代码

View decorView = getWindow().getDecorView();
decorView.setOnSystemUiVisibilityChangeListener
        (new View.OnSystemUiVisibilityChangeListener() {
    @Override
    public void onSystemUiVisibilityChange(int visibility) {
        // Note that system bars will only be "visible" if none of the
        // LOW_PROFILE, HIDE_NAVIGATION, or FULLSCREEN flags are set.
        if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
            // TODO: The system bars are visible. Make any desired
            // adjustments to your UI, such as showing the action bar or
            // other navigational controls.
// again hide it
        } else {
            // TODO: The system bars are NOT visible. Make any desired
            // adjustments to your UI, such as hiding the action bar or
            // other navigational controls.
        }
    }
});

工作,但它松开了软输入调整大小参数。我没有使用ScroolView。我会发布布局。不,只是继续滚动。设置全屏不应影响windows行为,但确实会影响。请查找支持此行为的文档。检查。不管怎样,我会查看的,谢谢:)发布你的布局代码
