How to remove repeatable keys, key preview of the Android custom keyboard

Question

How to remove repeating keys, key preview of Android Custom Keyboard. I used following method to remove key preview of the keys that I want. But that method is not working for repeatable keys. (android:isRepeatable="true") If the key is not repeatable, following method is working.

delete key xml

<Key android:codes="-5"
        android:keyWidth="13%p"
        android:keyIcon="@drawable/ic_key_delete_white"
        android:keyBackground="@color/dark_key_background"
        android:isRepeatable="true"
        android:horizontalGap="3.5%p"
        android:keyEdgeFlags="right"/>

Input method service Class

@Override
public void onPress(int primaryCode) {
    if (primaryCode == -1 
            || primaryCode == -5){
        kv.setPreviewEnabled(false);
    }
}

@Override
public void onRelease(int primaryCode) {
    if(primaryCode == -1 
            || primaryCode == -5){
        kv.setPreviewEnabled(true);
    }
}

Revers setPreviewEnabled flag..

public void onCreate() {

    mInputView.setPreviewEnabled(false);

}

public void onPress(int primaryCode) {
    if (primaryCode==-1||primaryCode==-2||primaryCode==-5||primaryCode==-4){

    } else {
       mInputView.setPreviewEnabled(true);
    }
}

public void onRelease(int primaryCode) {
    mInputView.setPreviewEnabled(false);
}
