Android：不同按钮的活动相同，但动作不同

Question

I was wondering if there is any way to call the same activity for different buttons, but do different things for each one..
More specific.. I have one activity with about 10 buttons on it and if I do it traditionally, every time I press a button, I have to create an activity for each one and as a result, I will have more than 15 java files..
So, I was wondering if there is any way, all the buttons, show to the same activity (which is easy, I will "intent" to show the same activity), but on that activity, depending on the button I press, do different actions..

For example, all the buttons show on Buttons.java, but inside exist a TextView and every time show another text, depending on the buttons I press -> Text1 (for Button1), Text2 (for Button2), Text3 (for Button3)...

Do you have any ideas?? Thank you!!

You can pass some information to activity when you want to start it... for example:

        button1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(getContext(), ExampleActivity.class);
                //There is no limit for number of Extras you want to pass to activity
                intent.putExtra("buttonNumber", 1);
                startActivity(intent);
            }
        });

ExampleActivity.java

public class ExampleActivity extends Activity {

int pressedButtonNumber;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_add_poll);
    pressedButtonNumber = getIntent().getExtras().getInt("buttonNumber");
    switch(pressedButtonNumber){
         case 1:
         //Do Something for clicking button 1 scenario
         break;
    }
}
