让TextView中的文本动起来

public class MarqueeTextView extends TextView {

    public MarqueeTextView(Context context) {
        super(context);
    }

    public MarqueeTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MarqueeTextView(Context context, AttributeSet attrs,
                           int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean isFocused() {
        return true;
    }

}

使用方法为

 <com.xxx.MarqueeTextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:ellipsize="marquee"
                android:marqueeRepeatLimit="marquee_forever"
                android:singleLine="true"
                 />
