底部导航栏使用键盘向上移动 [英] Bottom Navigation bar moves up with keyboard
本文介绍了底部导航栏使用键盘向上移动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在片段中使用滚动视图，但当键盘按应有的方式显示时，屏幕不会向上滚动。 以下是场景： 我有mainActivity，它有底部导航栏，外加一个框架布局，作为活动的容器。 代码如下：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity"
>
<FrameLayout
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" />
<android.support.design.widget.BottomNavigationView
android:background="@color/clear_white"
android:id="@+id/navigation"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_alignParentBottom="true"
app:itemIconTint="@color/blue_navbar_icon"
app:itemTextColor="@color/blue_navbar_icon"
app:menu="@menu/navigation" />
</RelativeLayout>
片段屏幕有一些输入字段和按钮，这些输入字段和按钮包装在受限布局中，然后在scllView中包装约束布局，以便在键盘处于活动状态时可以向上滚动。 以下是片段XML文件的代码：

这里还有我的清单文件：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.eapple.tripdatacollection">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".Main2Activity"
android:windowSoftInputMode="adjustResize"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ViewSavedLocations" />
<activity android:name=".fireBaseUpdates" />
<activity android:name=".SignInActivity" />
<activity android:name=".ForgotPasswordActivity" />
<activity android:name=".UploadDataActivity" />
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main2" />
</application>
</manifest>
但它不能按预期方式工作。 1)底部导航栏随键盘弹出，如下图所示：Screenshot
我希望底部导航栏保持在底部，或者在键盘处于活动状态时消失。
推荐答案
解决方案如下，我使用此接口解决问题：https://github.com/yshrsmz/KeyboardVisibilityEvent。
步骤：
1)在androidManifest文件中：
Add the following tag: android:windowSoftInputMode="adjustResize"
就像我在这里做的：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.eapple.tripdatacollection">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".Main2Activity"
android:windowSoftInputMode="adjustResize"
>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ViewSavedLocations" />
<activity android:name=".fireBaseUpdates" />
<activity android:name=".SignInActivity" />
<activity android:name=".ForgotPasswordActivity" />
<activity android:name=".UploadDataActivity" />
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main2" />
</application>
</manifest>
2)在build.grade文件(App)中添加以下依赖项
依赖项{ 实施‘net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:2.1.0’ )
3)将以下代码添加到Activity onCreate方法中：
KeyboardVisibilityEvent.setEventListener(
getActivity(),
new KeyboardVisibilityEventListener() {
@Override
public void onVisibilityChanged(boolean isOpen) {
// some code depending on keyboard visiblity status
}
});
这是我的Java文件：

private static SavedLocationsFragment savedLocationsFragment;
private View rootView;

private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_profile:
loadFragment(profileFragment);
return true;
case R.id.navigation_saved_locations:
loadFragment(savedLocationsFragment);
return true;
case R.id.navigation_add_location:
loadFragment(addLocationFragment);
return true;
}
return false;
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
addLocationFragment = new AddLocationFragment();
savedLocationsFragment = new SavedLocationsFragment();
profileFragment = new ProfileFragment();
rootView = findViewById(R.id.root_view);
final BottomNavigationView navigation = findViewById(R.id.navBar);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
navigation.setSelectedItemId(R.id.navigation_add_location);
loadFragment(addLocationFragment);
KeyboardVisibilityEvent.setEventListener(
this,
new KeyboardVisibilityEventListener() {
@Override
public void onVisibilityChanged(boolean isOpen) {
Log.d(TAG,"onVisibilityChanged: Keyboard visibility changed");
if(isOpen){
Log.d(TAG, "onVisibilityChanged: Keyboard is open");
navigation.setVisibility(View.INVISIBLE);
Log.d(TAG, "onVisibilityChanged: NavBar got Invisible");
}else{
Log.d(TAG, "onVisibilityChanged: Keyboard is closed");
navigation.setVisibility(View.VISIBLE);
Log.d(TAG, "onVisibilityChanged: NavBar got Visible");
}
}
});
}
private void loadFragment(android.support.v4.app.Fragment fragment) {
android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
}
