Displays text to the user and optionally allows them to edit it. A TextView is a complete text editor, however the basic class is configured to not allow editing; seeEditText for a subclass that configures the text view for editing.
向用户显示文本，并且可以选择允许用户编辑它。TextView是一个完整的文本编辑器，但是基类被配置成不可编辑的；请参考EditText子类，它被配置成可编辑的文本视图。

To allow users to copy some or all of the TextView's value and paste it somewhere else, set the XML attributeandroid:textIsSelectable to "true" or callsetTextIsSelectable(true). ThetextIsSelectable flag allows users to make selection gestures in the TextView, which in turn triggers the system's built-in copy/paste controls.
为了允许用户复制部分或全部TextView的内容并将其粘贴到其他地方，可以设置XML属性android:textIsSelectable为true或调用setTextIsSelectable(true)。textIsSelectable表示允许用户在TextView中做出手势，这将会触发系统内置的复制/粘贴操作。
