Here we are using two buttons for these two further actions. so please help us to get these two actions in a single button click..

回答1:
Looking at your code and assuming that the individual clicks to all the buttons are working well, here's what you have to do,
Move the emailing code pre4sent in your button4.setOnClickListener to a seperate method, say emailRecordng()
Call this method from your onActivityResult in the *if(resultCode==RESULT_CANCELED)*
block.
This way, when you click the imageButton, it will first record the voice for you and then it will be directly sent via the email from your onActivityResult()
Let me know if this helps
