每当用户选择EditText
中的文字时,我都想显示一个弹出窗口。
以下是我要做的事情:(来自Google文档应用的屏幕截图)
我还想在该弹出窗口中添加自定义操作。
关于如何实现这一目标的任何想法?
编辑:我特别想要一个浮动弹出窗口,就像屏幕截图中显示的那样,而不是ActionMode
,因为有很多有价值的信息会显示在appbar中。
我知道我可以让动作模式按下它下面的屏幕内容。但我真的需要一个文本选择弹出窗口。
答案 0 :(得分:0)
让我们看看如果为给定textIsSelectable
设置true
属性textView
,您将获得的默认行为。
onLongPress
上的{p> TextView
你会得到这个
根据android的API级别,事情可能会有所不同,
现在让我们自定义一些东西,
我假设您将使用support library v7
,因此为ToolBar
制作了内容。
确保您的应用程序主题具有包含此元素的样式。

长按textView
