Answer 1

There are several options.

Create a static variable:

private static int buttonClickCount = 0;

public void but1_Count(View v){
    buttonClickCount++;
    v.settext("Clicked " + buttonClickCount);
}

Create custom button by extending base button class and implement onClickListener:

public class MyButton extends Button implements View.OnClickListener {
    private int counter = 0;
    public MyButton(...){
        this.setOnClickListener(this);
    }
    public void onClick(View v) {
        counter++;
        v.setText("Clicked"+counter);
    }
}

Extract value from clicked button, parse it as int, and increment:

public void but1_count(View v){
    int curr = Integer.parseInt(v.getText().toString());
    v.setText(""+curr);
}

Answer 2

private static int counter = 0;

button1.setOnClickListener(new OnClickListener(){
    @Override
    onClick(View v){
       counter += 1
       button.setText("Some text" + counter);
    }
 });
