所有按钮的方法相同（拨号方式）

Question

我正在创建一个电话本应用，其中已经加载了电子邮件。！[布局中有名称和数字。我已经定义了数字。] [1] 应用图片位于此链接中：http://imgur.com/TPIupGg

这是xml文件。

我不得不编写java代码来拨打这个号码。但问题是我必须为每个数字和每个按钮编写java代码。这使得java代码冗长.java代码如下所示。所以有什么办法对所有按钮使用相同的方法（拨号）。因此可以减少java代码。电话号码保存在值＆gt;字符串中。

Answer 1

为什么必须为每个按钮定义？就这样做吧

a1.setOnClickListener(this);
a2.setOnClickListener(this);
.....
a7.setOnClickListener(this);

现在让您的类实现OnClickListener并定义Overridden onClick（）。
您将获得所有点击的事件。
