dialog的定制 ：

yingyong = (ImageView)findViewById(R.id.yingyong);
yingyong.setOnClickListener(this);
shudian = (ImageView)findViewById(R.id.shudian);
shudian.setOnClickListener(this);
baojia = (ImageView)findViewById(R.id.baojia);
baojia.setOnClickListener(this);
}

效果图：
第二种情况：
addCustomDlg = new Dialog(this, R.style.dialog);
addCustomDlg.setContentView(R.layout.add);
addCustomDlg.show();
confirmBtn = (Button) addCustomDlg.findViewById(R.id.confirmBtn);
edit = (EditText) addCustomDlg.findViewById(R.id.txt);
edit.setText("");
btn_back = (ImageButton) addCustomDlg.findViewById(R.id.btn_back);
btn_back.setOnClickListener(this);
confirmBtn.setOnClickListener(this);
直接从dialog中获取控件，并绑定事件
效果：
