Cómo agregar scrollview a keyboardView en android

Question

He estado tratando de agregar scrollview a mi teclado personalizado de Android Ime, pero nada he intentado hasta ahora.

Aquí hay parte de mi código

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;
}

Aparece el siguiente error

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

Esperado: desplácese como la imagen a continuación (no se puede cargar aquí, parece que mi reputación no es suficiente para eso :))

Intenta hacer este cambio:

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;
}
