extends AppCompatActivity and LinearLayout

Question

there's a way to extends AppCompatActivity and LinearLayout?

when I do this , it's full of error

public class MessageContainerView extends AppCompatActivity,LinearLayout implements OnLayoutChangedListener, OnCreateContextMenuListener,OnClickListener,TextToSpeech.OnInitListener 

How can I solve that?

Answer 1

Java basic :

A class can only extend one other class. A class can implement several interfaces.

Please refer the following link Implements vs extends: When to use? What's the difference?

Answer 2

You can extend either AppCompatActivity or LinearLayout, but not both. Java does not allow to multiple inheritance

Answer 3

you cannot extends multiple class in a single class because android is java based and java cannot support multiple inheritances using the class.So you can only one class extends at a time
