    if (getItem(position).getMonth() != mCal.get(Calendar.MONTH)) 
     txt.setTextColor(Color.parseColor("#FF787878")); 
    else 

     txt.setTextColor(Color.parseColor("#FF000000")); 

     if(DaliyScreenActivity.month_member_id_arr.contains(txt.getText().toString())){    

      convertView.setBackgroundColor(Color.YELLOW); 
      convertView.setBackgroundColor(android.graphics.Color.rgb(230, 187, 60));    
     }  
    } 
static class ViewHolder { 
    TextView txtDate; 
    TextView txtEventCount; 
} 

}

Answer 1

在你getView方法...更改最后if..else

此，

if (getItem(position).getMonth() != mCal.get(Calendar.MONTH)) 
{ 
     txt.setTextColor(Color.parseColor("#FF787878")); 
} 
else 
{ 
     txt.setTextColor(Color.parseColor("#FF000000")); 

      if(DaliyScreenActivity.month_member_id_arr.contains(txt.getText().toString())){    

      convertView.setBackgroundColor(Color.YELLOW); 
      convertView.setBackgroundColor(android.graphics.Color.rgb(230, 187, 60));    
     }  
} 

我的意思是说让你的代码来改变背景到else部分的黄色。

检查，凡不当月的细胞都将置自己灰色的文字颜色和两种文字颜色设置为相同的颜色作为背景，甚至更好设置空文本那些细胞。

if (getItem(position).getMonth() != mCal.get(Calendar.MONTH)) 
    txt.setTextColor(Color.parseColor("#88CCCCCC")); 

或

if (getItem(position).getMonth() != mCal.get(Calendar.MONTH)) 
    txt.setText("");
