                    android:scrollbars="vertical"
                    android:scrollingCache="false" />
                 <!-- 按“返回键”回到我的空间 -->
                <TextView" />
            </RelativeLayout>
        </LinearLayout></RelativeLayout>补充这个ListView所在的xml文件的架构

        </LinearLayout>
     
    </RelativeLayout>
      

  3.   

    public class AlwaysMarqueeTextView extends TextView { public AlwaysMarqueeTextView(Context context) { super(context); } public AlwaysMarqueeTextView(Context context, AttributeSet attrs) { super(context, attrs); } public AlwaysMarqueeTextView(Context context, AttributeSet attrs,
    int defStyle) { super(context, attrs, defStyle); } // 始终返回true，即一直获得焦点 @Override
    public boolean isFocused() { return true; }}
     <com.atool.ui.AlwaysMarqueeTextView
                        android:id="@+id/tvContent"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:ellipsize="marquee"
                        android:marqueeRepeatLimit="marquee_forever"
                        android:singleLine="true"
                        android:text="12345678901234567890 "
                       />
    这个是我写的
      

  4.   

    你这种方法我试过了不行，不过有一种情况可以行的通，就是把我上面的那个xml文件里ListView所在的RelativeLayout上面的那些空间都去掉，也即是只剩下<RelativeLayout
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" >
                <!-- 暂无节目预告信息 -->
                <TextView />
                <!-- 显示节目预告的数据 -->
                <ListView
                    android:id="@+id/program_detail_listview"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginBottom="@dimen/launcher_detail_listview_marginbottom"
                    android:layout_marginLeft="@dimen/launcher_detail_padding"
                    android:layout_marginRight="@dimen/launcher_detail_padding"
                    android:layout_marginTop="@dimen/launcher_detail_listview_margintop"
                    android:alwaysDrawnWithCache="true"
                    android:clickable="false"
                    android:focusable="true"
                    android:divider="@null"
                    android:dividerHeight="@dimen/launcher_detail_listview_scrollbar_divider"
                    android:fadeScrollbars="false"
                    android:fadingEdge="none"
                    android:listSelector="#00000000"
                    android:scrollbarFadeDuration="0"
                    android:scrollbarSize="@dimen/launcher_detail_listview_scrollbar_size"
                    android:scrollbarThumbVertical="@drawable/scroll_thum_selector"
                    android:scrollbarTrackVertical="@drawable/scroll_track_selector"
                    android:scrollbars="vertical"
                    android:scrollingCache="false" />
                 <!-- 按“返回键”回到我的空间 -->
                <TextView" />
            </RelativeLayout>这种情况下，可以实现跑马灯效果，但是加上上面的东西就不会出现跑马灯效果
      

  5.   

    现在的情况是只有获取焦点的时候才能实现跑马灯，我要的效果是每一个TextView都实现跑马灯
      

  6.   

    必须要获取焦点才能实现跑马灯，可以强制每个textview获取焦点啊
      

  7.   


     <com.atool.ui.AlwaysMarqueeTextView
                        android:id="@+id/tvContent"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:ellipsize="marquee"
                        android:marqueeRepeatLimit="marquee_forever"
                        android:singleLine="true"
                        android:text="12345678901234567890 "
                       />

    我也遇到过这个问题，不太记得怎么搞得了。你试试去掉所有控件这两个属性
    android:clickable
    android:focusable
    item的布局，给LinearLayout加一个属性：
    android:descendantFocusability="blocksDescendants"
    我也不知道行不行，试试吧。
