判断收件箱是不是为空以及修改textView文本颜色等

Uri uriSMSURI = Uri.parse("content://sms/inbox"); 
Cursor cur = mContext.getContentResolver().query(uriSMSURI, null, null, null, null); 
boolean ret = cur.getCount() > 0; 

 

 

2.通过样式表

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <style name="CodeFont" parent="@android:style/TextAppearance.Medium"> 
        <item name="android:textColor">#00FF00</item> 
        <item name="android:typeface">monospace</item> 
    </style> 
</resources> 

  然后如此使用

<TextView style="@style/CodeFont" />
