嗨，我想要做的是读取一个 xml 文件，该文件具有两个值颜色和名称，并显示名称并更改列表中该单个项目的背景颜色。有谁知道如何做到这一点？

这是我的xml

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

<resources>
    <string-array name="menu_array">
    <item>
        <name>Page1</name>
        <colour>#ffffff</colour>
    </item> 
    <item>
        <name>Page2</name>
        <colour>#ffffBB</colour>
    </item> 
     <item>
        <name>Page3</name>
        <colour>#fff45f</colour>
    </item> 
    <item>
        <name>Page4</name>
        <colour>#ffff00</colour>
    </item> 
 </string-array> 
</resources>

Change your String Array to atleast look like this:

    <string-array name="menu_array">

    <item>
      Page1 #ffffff
    </item> 

    <item>
      Page2 #ffffBB
    </item> 

    <item>
     Page3 #fff45f
    </item> 

    <item>
     Page4 #ffff00
    </item> 

    </string-array>

I have tried to parse the string-array you specified,I obtained the result of the form:

   Page1 #ffffff

This is,as far as I am concerned practically useless as you will have to still split your code using(where list is the actual string array):

        String[] cmenu =list[i].split("#");
        item.name=cmenu[0];
        item.colour="#"+cmenu[1];
        menuList.add(item);

Or you could use a subString method to do it.However I could not parse the colour value from your arrangement(always gave me a NumberFormatException) while the one I specifed seemed to work fine with:

           int Color.parseColor(String color)

This is the code of the getView method of the custom adapter I created for the purpose of solving the problem:

            @Override
        public View getView(int position, View convertView, ViewGroup parent) {
       View row=convertView;
       TextView textView;
       if(row==null)
      {
        row=inflater.inflate(resourceId, parent, false);
        textView=(TextView)row.findViewById(R.id.text1);
        row.setTag(R.id.text1,textView);
      }
       else
        textView=(TextView)row.getTag(R.id.text1);
        textView.setText(menuList.get(position).name);        
    try{    
        Log.d(TAG, menuList.get(position).colour);                  
        row.setBackgroundColor(Color.parseColor(menuList.get(position).colour));    
       }
       catch(Exception ex)
       {
         Log.e(TAG, "Still does not work");
       }
    return row;
}

NOTE:item is an object of ColouredMenuItem which just wraps String name,colour in a class.

The customAdapter has the constructor:

     MadAdapter(Context context,List<ColouredMenuItem> list,int resourceId)
{
    this.context=context;
    this.menuList=list;
    this.resourceId=resourceId;
    inflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

EDIT:You could also create an XML file that you could add to assets and parse it using any of the parsers available.

I'm afraid you'll have to parse item values in your custom adapter or use two different arrays, one for names and another for colors
