Issue

I have an android application, and I use ahbottomnavigation or BottomNavigationView. I need the bottom navigation bar to hide when the keyboard appears.

This is my AndroidManifest.xml:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.newest">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
        android:launchMode="singleTask"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
    </application>
</manifest>

Solution

Refer to android:windowSoftInputMode.

Value	Description
"`stateUnspecified`"	The state of the soft keyboard (whether it is hidden or visible) is not specified. The system will choose an appropriate state or rely on the setting in the theme. This is the default setting for the behavior of the soft keyboard.
"`stateUnchanged`"	The soft keyboard is kept in whatever state it was last in, whether visible or hidden, when the activity comes to the fore.
"`stateHidden`"	The soft keyboard is hidden when the user chooses the activity — that is, when the user affirmatively navigates forward to the activity, rather than backs into it because of leaving another activity.
"`stateAlwaysHidden`"	The soft keyboard is always hidden when the activity's main window has input focus.
"`stateVisible`"	The soft keyboard is made visible when the user chooses the activity — that is, when the user affirmatively navigates forward to the activity, rather than backs into it because of leaving another activity.
"`stateAlwaysVisible`"	The soft keyboard is visible when the window receives input focus.
"`adjustUnspecified`"	It is unspecified whether the activity's main window resizes to make room for the soft keyboard, or whether the contents of the window pan to make the current focus visible on-screen. The system will automatically select one of these modes depending on whether the content of the window has any layout views that can scroll their contents. If there is such a view, the window will be resized, on the assumption that scrolling can make all of the window's contents visible within a smaller area. This is the default setting for the behavior of the main window.
"`adjustResize`"	The activity's main window is always resized to make room for the soft keyboard on screen.
"`adjustPan`"	The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

Just modify android:windowSoftInputMode to adjustPan.

 <activity android:name=".MainActivity"
        android:windowSoftInputMode="adjustPan">
