我整個移動的view是繼承了HorizontalScrollView,但是發現我遙控器向右移動的時候,view沒焦點了,我view裡面有一個跑馬燈效果,就是在有焦點的時候才出現跑馬燈,沒焦點的時候隱藏這段顯示的文字,如下就是跑馬燈的效果並解決了焦點衝突問題：

public class AutoScrollTextView extends TextView {

    public AutoScrollTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
 
init();
}

    public AutoScrollTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
init();
}

    public AutoScrollTextView(Context context) {
        super(context);
init();
}

    @Override
protected void onFocusChanged(boolean focused, int direction,
Rect previouslyFocusedRect) {
        if 
 
(focused){
            super.onFocusChanged(focused, direction, previouslyFocusedRect);
}else{
            super.onFocusChanged(false, direction, previouslyFocusedRect);
}
    }

    @Override
public void onWindowFocusChanged(boolean focused) {
        if (focused)
            super.onWindowFocusChanged(focused);
 
}

    @Override
public boolean isFocused() {
        return true;
}

    private void init() {
        setEllipsize(TextUtils.TruncateAt.MARQUEE);// 對應android:ellipsize="marquee"
setMarqueeRepeatLimit(-1);// 對應android:marqueeRepeatLimit="marquee_forever"
setSingleLine();// 等價於setSingleLine(true）
}
    @Override
public void setVisibility(int visibility) {
        super.setVisibility(visibility);
        if(visibility== View.VISIBLE){
            setFocusable(true);
}else if(visibility==View.INVISIBLE){
            setFocusable(false);
}
    }
}
