Android How to set click listener of a button which is from another layout xml file

Question

MainActivity shows a viewpager so there are 3 layout files:activity_main.xml、card1.xml and card2.xml Now I want to get view from card1.xml and set the listener. what should I do?

I tried using this:

LayoutInflater layout=this.getLayoutInflater();
View view=layout.inflate(R.layout.card1, null);
Button b=(Button)view.findViewById(R.id.b);

then set OnClickListener:

b.setOnClickListener(new MyClickListener(0));

but useless.

you have to use adapter for this. – akhil batlawala Sep 21 '15 at 05:14 — akhil batlawala, Sep 21 '15 at 05:14

In your card1.xml, you can add a onClick attribute, and just provide the method name as the attribute's value, like this:

<Button android:id="@+id/mybutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click me!"
android:onClick="myMethod" />

Now in you MainActivity.java file, create a public method with return type as void, and which takes in a View parameter, like this:

    public void myMethod(View v) {  
    // do your thing here  
    }

public class MyClickListener implements OnClickListener {

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.your_btn_id:
            // your code 

            break;


        }

    }

}

another way is you can add button click listener in your card1.xml fragment class.
