Question

I am really stuck here. What I want is not simple (for me), however I’ve been programming android a year now.
What I want is a listview with an imageview, a textview, a checkbox, and another textview in each row.
Let’s have a textview and a checkbox first in the layout.
Based on this tutorial I managed to do that (there are a lot, but this seems to be the best for me). I have a listview populated with textviews and checkboxes.

This is the result:

This is how I get the text of textview I click on:

 textView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            TextView tv = (TextView) v ;
            String text_of_clicked_textview = tv.getText().toString();
            Log.i("TAG", "" + text_of_clicked_textview);
        }
    });

So When I click on Mercury, I get Mercury in the text_of_clicked_textview variable.

But how can i check which checkbox I clicked on? E.g I click on the 3rd checkbox, I want to now it is in the row of Earth. Best would be if I get to know both the text of textview in the row of the listview(Earth) and and number of the item (3).

I guess I have to set an onClickListener on the checkbox but what next?

checkBox.setOnClickListener( new View.OnClickListener() {
      public void onClick(View v) {
        CheckBox cb = (CheckBox) v ;

      }
    });

This is XML for Custom Row in ListView :

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

        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/camera_icon" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <CheckBox
            android:id="@+id/checkBox1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="" 
     />

</LinearLayout>

This is Complete Activity in which List is implemented :
Just Copy this Activity for test then understand code. Place one listview in main Activity
