如何设置Crouton Toast内按钮的监听器并使用该按钮清除Crouton Toast？

Question

我有一个应用程序，在操作栏下方显示吐司。我正在使用Crouton库来显示吐司。在这里，我为toast放置自定义布局，该布局包含一个textview和一个按钮（用于关闭选项）。所以Toast出现了按钮。如果我点击它应该关闭吐司但没有任何反应..下面这个例子的代码。感谢任何帮助

MainActivity.java

public class MainActivity extends SherlockActivity implements OnClickListener {

private View customToastView;
private TextView customToastMessageView;
private Button customToastCloseButton;
private Button doneButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    doneButton = (Button) findViewById(R.id.done_button);
    customToastView = getLayoutInflater().inflate(R.layout.toast_custom_layout, null);
    customToastMessageView = (TextView) customToastView.findViewById(R.id.messages);
    customToastCloseButton = (Button) customToastView.findViewById(R.id.close_button);
    customToastCloseButton.setOnClickListener(this);
    doneButton.setOnClickListener(this);
}

@Override
public void onClick(View v) {

    switch (v.getId()) {
        case R.id.done_button:
            Crouton.cancelAllCroutons();
            customToastMessageView.setText("Message");
            Crouton.show(this, customToastView);
            break;
        case R.id.close_button:
            Crouton.cancelAllCroutons();
            break;
      }
  }
}
