如何集中时，改变的TableRow的背景颜色？ [英] How to change the background color of a TableRow when focused?

问题描述

我有一个表行，我试过很多事情来改变其颜色，当它集中，但集中时，它永远不会改变颜色。有没有办法做到这一点？我想这也该变了颜色上的点击，但只有当它的聚焦：

  r.setOnTouchListener（新OnTouchListener（）{
    公共布尔onTouch（查看为arg0，MotionEvent ARG1）{
        如果（arg0.isFocused（））
        {
            arg0.setBackgroundColor（Color.BLUE）;
            //arg0.isFocused（）;
        }
        返回false;
}}）;
 

解决方案

您需要设置行的背景颜色为状态列表绘制（处理选择，pressed，主动，非主动）。

I have a table row and I tried many things to change its color when it's focused, but it never changes color when focused. Is there any way to do this? I tried this also which changed color on click but only when its' focused:

r.setOnTouchListener(new OnTouchListener() {
    public boolean onTouch(View arg0, MotionEvent arg1) {
        if(arg0.isFocused())
        {
            arg0.setBackgroundColor(Color.BLUE);
            //arg0.isFocused();
        }
        return false;
}});

解决方案

You need to set the background color of your row to a state list drawable (that handles select, pressed, active, non-active).

http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList

    <?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!--  Active state --> 
    <item android:state_selected="true" android:state_focused="false" android:state_pressed="false" android:drawable="@android:color/transparent" />     
<!--  Inactive state--> 
    <item android:state_selected="false" android:state_focused="false"         android:state_pressed="false" android:drawable="@android:color/transparent" />
     <!--  Pressed state-->
     <item android:state_pressed="true" android:drawable="@android:color/yellow" /> 
    <!--  Selected state (using d-pad) -->
     <item android:state_focused="true" android:state_selected="true"         android:state_pressed="false" android:drawable="@android:color/yellow" />
 </selector>
