    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:lines="1"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="true"
    android:text="hello all how are you"
    android:textColor="#ff4500" 
    />

MarqueeText = (TextView)ShowTheMessages.this.findViewById(R.id.marqueetext);

改变这一行，并尝试...

change this line and try...

android:text="hello all how are you hello all how are you hello all how are you hello all how are you"
TextView txtView=(TextView) findViewById(R.id.marqueetext);
txtView.setSelected(true);

 <TextView
    android:id="@+id/marqueetext"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:lines="1"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="true"
    android:text="hello all how are you hello all how are you hello all how are you hello all how are you"
    android:textColor="#ff4500" 
    />
