Android的TextView中，在一个ListView选取框将无法运行动画它显示在拳头时间 [英] Android's TextView with marquee in a ListView won't animate for the fist time it is shown

问题描述

我有一个自定义适配器一个ListView。在它的每一个项目都包含一个TextView。

I've got a ListView with a custom adapter. Every item in it contains a TextView.

<TextView
    android:id="@+id/chat_name"
    android:layout_height="48dp"
    android:layout_width="match_parent"
    android:textColor="#FFFFFF"
    android:gravity="center_vertical"
    android:ellipsize="marquee"
    android:marqueeRepeatLimit="marquee_forever"
    android:singleLine="true"
    android:focusable="false"
    android:focusableInTouchMode="false"/>

我需要这个TextView中不成为焦点，因为我靠 onListItemClick（）方法。当我了解， onListItemClick（）如果你设置不会触发聚焦的=真正的。

I need this TextView to not be focusable, because I rely on the onListItemClick() method. As I learned, onListItemClick() won't fire if you set focusable="true".

在我设置适配器：

TextView chatName = (TextView) v.findViewById(R.id.chat_name);
chatName.setText(chat.getChatName());
chatName.setSelected(true);

和它的作品每一次，但第一个。当一个项目被添加到该适配器它示出了在列表视图，但它不marqueed。当单击项目时，则显示另一个活动。用户返回到ListView之后，该项目突然marqueed。我想这marqueed所有的时间。

And it works every time but first one. When an item is added to the adapter it shows on the listview, but it isn't marqueed. When item is clicked, another activity is displayed. After the user returns to the ListView, the item is suddenly marqueed. I want it marqueed all the time.

我已经尝试与覆盖 isFocused（）来始终返回true的方法继承TextView的，但是这并没有帮助。行为保持不变。我也尝试了不同值可聚焦和 focusableInTouchMode 属性，但没有成功。

I have already tried subclassing the TextView with a method that overwrites isFocused() to always return true, but that didn't help. Behavior remained the same. I also experimented with various values of focusable and focusableInTouchMode attributes, but with no success.

推荐答案

请使用requestFocus（）方法的功能如下。

Please use requestFocus() function as follows.

chatName.setSelected(true);
chatName.requestFocus();

我会工作。
