1.使用內部匿名類：

private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// 在此處新增邏輯
}
});
}
 

public class MainActivity extends Activity implements View.OnClickListener {
  private Button button;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button);
        button.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
    switch (v.getId()){
        case R.id.button:{
            Toast.makeText(MainActivity.this,"採用實現介面的方式實現了監聽", Toast.LENGTH_SHORT).show();
        }break;
        default:break;
    }
    }
}
