一般在開發中，都是讓Activity實現OnClickListener()介面,覆寫其onClick（）方法

public class MainActivity extends Activity implements OnClickListener{

private Button buttonOne;
@Override
public void onCreate(Bundle savedInstanceState ){
   super.onCreate(savedInstanceState);
   setContentView(R.id.activity_main);
   buttonOne=(Button)findViewById(R.id.buttonOne);
}
@Override
public void onClick(View v){
switch(v.getId())
case R.id.buttonOne:
Log.i("hello","hello");
 

}
