Actionbarsherlock custom layout clickable imageview

I am trying to make my imageview that is defined in my custom layout for Actionbarsherlock clickable. My activity first sets a layout:

setContentView(R.layout.myLayout);

The actionbar_layout is set in the same activity like this:

View cView = getLayoutInflater().inflate(R.layout.actionbar_layout,
            null);
    actionBar.setCustomView(cView);

The actual actionbar_layout looks like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:orientation="horizontal" >

<ImageView
    android:id="@+id/actionBarLogo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:paddingBottom="50dp"
    android:paddingLeft="10dp"
    android:paddingRight="50dp"
    android:paddingTop="50dp"
    android:scaleType="centerCrop"
    android:src="@drawable/logo" />

</LinearLayout>

Adding this:

actionBarLogo.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //code 
        }
    });

Results in a Nullpointer exception for this line:

actionBarLogo.setOnClickListener(new View.OnClickListener()

The custom layout works fine, i just need the imageview to be clickable. Any ideas how to fix this? How can my activity get a reference to my actionBarLogo id which is defined in actionbar_layout.xml?

Use ImageButton insteadOf ImageView

<ImageButton
    android:id="@+id/actionBarLogo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:paddingBottom="50dp"
    android:paddingLeft="10dp"
    android:paddingRight="50dp"
    android:paddingTop="50dp"
    android:scaleType="centerCrop"
    android:onClick="somemethod"
    android:src="@drawable/logo" />

Try something like this:

//your code
View cView = getLayoutInflater().inflate(R.layout.actionbar_layout,
        null);
actionBar.setCustomView(cView);

ImageView actionBarLogo = (ImageView) cView.findViewById(R.id.actionBarLogo);

actionBarLogo.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        //code 
    }
});

It should work.

as far as i understand your problem, its not possible to access the desired view, because its not part of the view or part of the window decoration. Check this post here, to find a workaround: https://stackoverflow.com/a/10187801/1965084
