如何使用代码模拟按钮单击? [英] How to simulate a button click using code?

问题描述

如何使用Android中的代码触发按钮点击事件?我想在发生其他事件时以编程方式触发按钮单击.

How can I trigger a button click event using code in Android? I want to trigger the button click programmatically when some other event occurs.

我正面临同样的问题

public void onDateSelectedButtonClick(View v){
    /*Something  Alarm Management 
    http://www.java2s.com/Code/Android/Core-Class/Alarmdemo.htm
    copied code from this site*/
}

按钮代码:

<Button
    android:onClick="onDateSelectedButtonClick"
    android:text="Set notification for this date" />

但是我想在没有OnClickEvent的情况下调用该函数OnLoadLayout

But I want to call that function OnLoadLayout without OnClickEvent

推荐答案

还有一种更好的方法.

View.performClick();

http://developer.android.com/reference/android/view/View.html#performClick()

这应该回答您所有的问题.每个View都会继承此功能，包括Button，Spinner等.

this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

请澄清一下，View没有静态的performClick()方法.您必须在View实例上调用performClick(). 例如，您不能只拨打

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call

View.performClick();

相反，请执行以下操作:

Instead, do something like:

View myView = findViewById(R.id.myview);
myView.performClick();
