Refresh listview setvisible all checkbox

I have a listview with my custom row.xml. Row.xml has a checkbox, imageview, textview and an imageview.

By default, the checkbox is visibility:GONE in the row.xml

In the code, I override the next method:

 @Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, v, menuInfo);

    checkBox=(CheckBox)findViewById(R.id.checkBox);
    checkBox.setVisibility(View.VISIBLE);

    myArrayAdapter.notifyDataSetChanged();

    }

}

But only get one row visible. I tried everything with the code, but i can´t find the solution. Any idea?

Kisses ^^

EDIT with my custom_row.xml

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://ift.tt/nIICcg"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <CheckBox
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/checkBox"
        android:checked="false"

        android:visibility="gone"
        />

    <ImageView
            android:layout_width="25dp"
            android:layout_height="25dp"
            android:src="@drawable/image"/>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="New Text"
            android:id="@+id/text1"/>

        <ImageView
            android:layout_width="25dp"
            android:layout_height="25dp"
            android:id="@+id/imageView"
            android:src="@android:drawable/ic_menu_add"
