本文介绍如何在Android应用中为按钮设置点击事件。主要包括使用Button的onClick属性声明动作方法，在显示按钮布局的活动中添加对应的方法，并确保该方法接受一个View参数。此外还介绍了从XML到Java代码实现方式。
Make a button action
1. use the Button onClick attribute to declare the name of the action method
2.Open the Activity that displays the layout with the Button
3.Add a method with a name matching the onClick attribute value
4.Make sure that method takes in a single View as a parameter
@string/haiku:
find it at strings.xml
<string name="haiku">I dreamed of a phone</string>
android development refernece:
developer.android.com
android:visibility="invisible"
<Button ...
android:onClick="onLoveButtonClicked">
The action method will be called on the activity that launched the screen.
public void onLoveButtonClicked(View view) {...}
From XML to Java (use the method: findViewById)
R file:
Button button = (Button) findViewById(R.id.Button01)
