StatusBar显示键盘何时显示

Question

我的活动使用了CollapsingToolbarLayout,我成功删除了StatusBar这样做:

View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

问题是,当softkeyboard弹出时,StatusBar再次出现,消耗宝贵的空间.

如何让它永久隐藏在ActivityView？

如果我将它设置为FullScreen,它可以工作,但我松了SOFT_INPUT_ADJUST_RESIZE参数.主窗口在softkeyboard显示时滚动,而不是根据需要调整大小.

@Override

    super.onResume();

    View decorView = getWindow().getDecorView();
    // Hide the status bar.
    int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    decorView.setSystemUiVisibility(uiOptions);
}

该活动使用NoActionBar方案(在清单上声明).

在您的样式活动样式中添加此行

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

除非你用你的活动内容包装ScrollView你不能在全屏活动中使用SOFT_INPUT_ADJUST_RESIZE

为此，您需要将布局内容包装在里面 ScrollView

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <!-- everything you already have -->

</LinearLayout>

告诉我它是否有效..
