ตัวอย่างการใช้ Listener กับหลายๆ View

Op1.java

Button btn1 = (Button)findViewById(R.id.btn1);
btn1.setOnClickLlistener(new OnClickListener() {
    public void onClick(View v) {
        // Button 1 Command
    }
});

Button btn2 = (Button)findViewById(R.id.btn2);
btn2.setOnClickLlistener(new OnClickListener() {
    public void onClick(View v) {
        // Button 2 Command
    }
});

Op2.java

OnClickLisetner listener new OnClickListener() {
    public void onClick(View v) {
        int id = v.getId;
        if(id == R.id.btn1) {
            // Button 1 Command
        } else if(id == R.id.btn2) {
            // Button 2 Command
        }
    }
}

Button btn1 = (Button)findViewById(R.id.btn1);
btn1.setOnClickLlistener(listener);

Button btn2 = (Button)findViewById(R.id.btn2);
btn2.setOnClickLlistener(listener);
