无法将TextView更改为Button

 

 activity_main.xml

<RelativeLayout  xmlns：android = “ http://schemas.android.com/apk/res/android” 

android：layout_width = “ match_parent” android：layout_height = “ match_parent” > <TextView android：layout_width = “ wrap_content” android：layout_height “ = ” wrap_content“ />     android：text =”蚂蚁在早晨醒来时会伸展。“

    android：id =“ @ + id / TextView”

 </ RelativeLayout>  

 

 

答：发现了你的问题。复制TextView代码并将其粘贴到下方TextView，现在您要做的就是更改TextView为Button：

 

<RelativeLayout  xmlns：android = “ http://schemas.android.com/apk/res/android” 

android：layout_width = “ match_parent” android：layout_height = “ match_parent” > <TextView android：layout_width = “ wrap_content” android：layout_height = “ wrap_content” /> <按钮android：layout_width = “ wrap_content” android：layout_height = “” wrap_content“ /> </ RelativeLayout>
