Android customview中的TextView onTouchEvent
我有一个自定义视图，在自定义视图中我创建了4个文本视图。我希望这些文本视图中的每一个都能响应触控事件。但是，文本视图本身不响应触控事件。但是，我可以为整个自定义视图创建一个ontouch侦听器。但是，我不希望整个视图都有ontouch事件，因为我希望拖放我创建的TextView。我尝试注册ontouch事件的x和y坐标，并假设如果ontouch事件在textview的范围内，则更改textview的坐标，但这太复杂了，因为如果一个textview被拖到另一个textview的坐标，则ontouch事件将“拾取”另一个文本视图，那么我将移动两个文本视图，这不是我想要的。总之，我想知道是否可以在customview中为textview在ontouch listener中设置，如果可能，为什么不工作：Android customview中的TextView onTouchEvent,android,android-canvas,Android,Android Canvas,我有一个自定义视图，在自定义视图中我创建了4个文本视图。我希望这些文本视图中的每一个都能响应触控事件。但是，文本视图本身不响应触控事件。但是，我可以为整个自定义视图创建一个ontouch侦听器。但是，我不希望整个视图都有ontouch事件，因为我希望拖放我创建的TextView。我尝试注册ontouch事件的x和y坐标，并假设如果ontouch事件在textview的范围内，则更改textview的坐标，但这太复杂了，因为如果一个textview被拖到另一个textview的坐标，则ontouc
