控件的思路是2個TextView壓在一起

-------注意更改第二版為可以居中版本,下載Demo后請覆蓋內(nèi)容

文件名:item_rcl.xml

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

        android:layout_centerHorizontal="true">

        <TextView

            android:layout_height="wrap_content"

            android:text="XINHAO_HAN"
            android:textColor="#00ff00"

    </LinearLayout>

    <RelativeLayout
        android:id="@+id/two"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/one">

        <TextView
            android:id="@+id/zzzz"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:scrollbars="horizontal"
            android:text="XINHAO_HAN"
            android:textColor="#ff00ff"
            android:textSize="20sp" />


    </RelativeLayout>


</RelativeLayout>

TextView使用的屬性如下:

XML:
android:scrollbars="horizontal"
java:
   textView.setMovementMethod(ScrollingMovementMethod
                .getInstance());
        textView.setHorizontallyScrolling(true); // 不讓超出屏幕的文本自動換行，使用滾動條
