使用< include>时如何使用Onclick事件标签 [英] How to use Onclick event when using <include> tag

问题描述

我两个班都有两个 java类和两个布局. 每个布局中都有一个按钮. 这两个类都扩展了Activity. 现在在第一种布局中，我使用了这样的 include 标签

I have two java class and two layout for both the class. Each layout is having one button in it. Both classes are extending Activity. Now in first layout I used include tag like this

<include 
    android:id="@+id/clicked" 
    layout="@layout/activity_main" />

我现在可以看到两个按钮，但是第二个按钮不起作用.

I can now see two buttons but the second button is not working.

推荐答案

首先您必须声明并初始化 include 视图，然后使用 view.findViewById()方法如下:

First You have to declare and initialise the include view and then decalre and initialise both buttons using view.findViewById() method as follows:

View includeView = (View)findViewById(R.id.clicked);
Button button1 = (Button)includeView.findViewById(R.id.button1ID); //decalre button like this
Button button2 = (Button)includeView.findViewById(R.id.button2ID);

然后设置其 onClickListeners

button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                //code whatever you want to do here
            }
        });

 button2.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                //code whatever you want to do here
            }
        });

解决了错字问题.应为 findViewById 上的 includeView . 很好的解释！

Fixed the typo. Should be includeView on the findViewById. Good explanation though!
