[Android TV 按键响应]listview的textview跑马灯在鼠标控制下失效的问题

问题：遥控按键选中的选项有跑马灯效果，但是鼠标事件来说，没有跑马灯效果

解题过程：重写一个类继承textview，永远获取焦点，不行。即使我再OnhoverListener里面实现onHover并且对textview获取了焦点，但是仍旧不行

解决方法：最后重写一个类继承textview，永远获取焦点，并且对textview调用了setSelected(true)之后就可以了。

public class MarqueeTextView extends TextView {
    public MarqueeTextView(Context con) {
        super(con);
    }

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

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

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

    @Override
    protected void onFocusChanged(boolean focused, int direction,
            Rect previouslyFocusedRect) {
    }

}

    <com.jrm.localmm.ui.view.MarqueeTextView
        android:id="@+id/ListNameTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="marquee"
        android:gravity="left"
        android:layout_marginLeft="2dip"
        android:marqueeRepeatLimit="marquee_forever"
        android:singleLine="true"
        android:textColor="@android:color/white"
        android:textSize="15sp" >
    </com.jrm.localmm.ui.view.MarqueeTextView>

holder.settingOptionTextView.setSelected(true);

另外总结下AN TV下的鼠标，遥控按键事件：

首先对于selector而言，在TV下面只有遥控按键能够触发全部的事件：focus,selected,press

<?xml version="1.0" encoding="UTF-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">

	<!-- 无焦点状怿-->

	<item android:state_focused="false" android:state_selected="false" android:state_pressed="false"

		android:drawable="@android:color/transparent" />

	<item android:state_focused="false" android:state_selected="true" android:state_pressed="false"

		android:drawable="@drawable/list_foucs" />

	<!-- 焦点状怿-->	

	<item android:state_focused="true" android:state_selected="false" android:state_pressed="false"

		android:drawable="@drawable/list_foucs" />

	<item android:state_focused="true" android:state_selected="true" android:state_pressed="false"

		android:drawable="@drawable/list_foucs" />

	<!-- 按下状怿-->

	<item android:state_pressed="true" android:drawable="@drawable/list_foucs" />

</selector>

鼠标能触发的只要点击的时候的press事件。

至于在鼠标操控下要怎么模仿按键事件选择某个item之后，背景图像变化的话 ，只能间接通过设置item的背景图像来实现了

    //refresh the focus state of listview item
    public void refreshItemFocusState(int index) {
        // TODO Auto-generated method stub
        Log.d(TAG, "refreshItemFocusState index = "+index) ;
        currentSelectedItemView =  listView.getChildAt(index);
        if(isEnterListviewLocation){
            if(oldSelectedItemView != null)
                oldSelectedItemView.setBackgroundResource(R.drawable.button_normal) ;
            if(currentSelectedItemView != null)
                currentSelectedItemView.setBackgroundResource(R.drawable.list_foucs);
            oldSelectedItemView = currentSelectedItemView ;
        }
    }
