Come aggiungere scrollview a keyboardView in Android

Question

Ho cercato di aggiungere scrollview alla mia tastiera personalizzata Android, Ime, ma nulla di ciò che ho provato non funziona fino ad ora.

Ecco parte del mio codice

keyboard.xml

<?xml version="1.0" encoding="UTF-8"?> 
<ScrollView 
    android:layout_height="wrap_content" 
    android:layout_width="wrap_content" 
    xmlns:android="http://schemas.android.com/apk/res/android"> 

    <android.inputmethodservice.KeyboardView 
     android:id="@+id/keyboard" 
     xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:isScrollContainer="true" 
     android:scrollbarAlwaysDrawHorizontalTrack="true" 
     android:scrollbarStyle="insideOverlay" 
     android:scrollbars="horizontal" 
     android:focusable="true" 
    /> 
</ScrollView> 

.java

@Override 
    public View onCreateInputView() { 
     context = getApplicationContext(); 
     ScrollView scroll = (ScrollView)getLayoutInflater().inflate(R.layout.keyboard,null); 
     kv = (KeyboardView)scroll.findViewById(R.id.keyboard); 
     keyboard = new Keyboard(this, R.xml.qwerty); 
     kv.setPreviewEnabled(false); 
     kv.setKeyboard(keyboard); 
     kv.setHorizontalScrollBarEnabled(true); 
     kv.canScrollHorizontally(1); 
     kv.setOnKeyboardActionListener(this); 

     return kv; 
    } 

ottengo l'errore sotto

> java.lang.IllegalStateException: The specified child already has a 
> parent. You must call removeView() on the child's parent first. 

atteso: Scorri come immagine in basso (non posso caricare qui, sembra che la mia reputazione non è sufficiente per questo :))

provare a fare questo cambiamento:

keyboard.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.inputmethodservice.KeyboardView 
    android:id="@+id/keyboard" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
/> 

my_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
      android:orientation="vertical" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:id="@+id/keyboard_layout"> 

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="match_parent" 
      android:layout_height="@dimen/example_height" 
      android:id="@+id/keyboard_scroll"> 
    </ScrollView> 

</LinearLayout> 

.java

@Override 
public View onCreateInputView() { 

    LinearLayout myView = (LinearLayout) View.inflate(this, R.layout.my_layout, null); 
    ScrollView scrollView = (ScrollView) myView.findViewById(R.id.keyboard_scroll); 

    KeyboardView kv = (KeyboardView) getLayoutInflater().inflate(keyboard.xml, null); 
    keyboard = new Keyboard(this, R.xml.qwerty); 
    kv.setKeyboard(keyboard); 
    kv.setOnKeyboardActionListener(this); 

    scrollView.addView(kv); 
    return myView; 
}
