Android之布局onClick属性写法规则

标签：

/** Called when the user clicks the Send button */
public void sendMessage(View view) {
    // Do something in response to button
}

In order for the system to match this method to the method name given to android:onClick, the signature must be exactly as shown. Specifically, the method must:

• Be public //一定是public的方法
• Have a void return value //一定是无返回值的方法
• Have a View as the only parameter (this will be the View that was clicked) //有且只有一个View类型的形参(希望被点到的View)
