Android textview 跑马灯文字滚动效果，androidtextview,设置如下TextView

设置如下TextView控件文件的XML：

<com.example.Mytext android:id="@+id/textview"

     android:layout_width="match_parent"     android:layout_height="20dp"     android:gravity="center"     android:singleLine="true"//限制行数为1行     android:ellipsize="marquee"//marquee 文字滚动     android:marqueeRepeatLimit="marquee_forever"//文字滚动次数：marquee_forever 无限次     android:focusable="true"//获取焦点     android:focusableInTouchMode="true"//获取触摸焦点     android:textColor="@color/red"    android:text="@string/text"         />

有其它布局如ScrollView等抢占焦点，需要自定义控件获取焦点：

public class Mytext extends TextView { public Mytext(Context context, AttributeSet attrs) { super(context, attrs); } @Overrideprotected void onFocusChanged(boolean focused, int direction,Rect previouslyFocusedRect) {if(focused){ super.onFocusChanged(focused, direction, previouslyFocusedRect);

 }}@Override  public void onWindowFocusChanged(boolean hasWindowFocus) {  if(hasWindowFocus){  super.onWindowFocusChanged(hasWindowFocus);

} } @Override publicbooleanisFocused(){ returntrue; } }
