我需要为xml drawable中的颜色设置不透明度值.但是当我尝试添加两个不透明度值(#20C0C0C0)时,不起作用.颜色看起来完全透明.

这是我的代码......

  <?xml version="1.0" encoding="utf-8"?>
  <shape xmlns:android="http://schemas.android.com/apk/res/android" >
     <corners
        android:radius="2dp" />
     <solid
        android:color="#CDCDCD" />
     <stroke
        android:width="2dp"
        android:color="@android:color/darker_gray" />
     <size 
        android:height="60dp"
        android:width="80dp"/>
   </shape>

有人有想法吗？谢谢你的帮助.

filter = nome.getText().toString();

tempCurs = getContentResolver().query(ContactsContract.Groups.CONTENT_URI,
    new String[]{ContactsContract.Groups._ID,ContactsContract.Groups.TITLE},
    ContactsContract.Groups.ACCOUNT_NAME + " =? " + " AND " + ContactsContract.Groups.TITLE + " !=? ",
    new String[]{accountName,nomeGrupo},
    null
    );      
if(tempCurs.moveToFirst())
    do{
        cursorContactosGrupos = getContentResolver().query(ContactsContract.Data.CONTENT_URI,
                new String[]{ContactsContract.CommonDataKinds.GroupMembership.DISPLAY_NAME, ContactsContract.CommonDataKinds.GroupMembership._ID},
