多个OnClick事件不适用于所有对象

时间:2017-06-26 20:40:58

标签: java android onclick

我已经制作了一个基本的Android布局,其中包含框架,图像和每个文本视图。

我遇到的问题是OnClick事件似乎只适用于前两个。我重新阅读了我的代码,无法理解为什么它不适用于所有的framelayouts ......

我对Android很陌生,所以我可能错过了一些明显的东西。

适用的java /活动代码:

    setContentView(R.layout.grid_current);

从ImageView和TextView中删除android:clickable=true

ImageView / TextView位于FrameLayout之上,因此如果您将android:clickable=true设置为这些子级,则会干扰点击侦听器而不会委托给父级(FrameLayout)。

实际上,您可以在此xml中的任何位置删除clickable属性,setOnClickListener会自动在视图上将Clickable设置为true。
