问题

        @Override
        public void onItemClick(final AdapterView<?> parent, View view, final int position, long id) 
        {

         // My code is here. I want make my image clickable. I don't want make it clickable in my CustomAdapter getView() method because it doesn't allows me open DialogFragment from there.
         // I already setted in xml of image clickable="true" and focusable = "false"
         //I'll admit for any help and thanks in advance

        }
}

If you take image Onclick from adapter,you cannot take setOnItemClickListener from listview event.I suggested you may take Onclick and insteadof setOnItemClickListener take Onclick from adapter.

First you have to add OnClickListener for Imageview in Adapter class like

viewHolder.button1.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    ((ListView) parent).performItemClick(v, position, 0); // Let the event be handled in onItemClick()
}

});

Then after you can access ImageView in onItemClick like

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    long viewId = view.getId();


if (viewId == R.id.button1) {
        Toast.makeText(this, "Button 1 clicked", Toast.LENGTH_SHORT).show();
    } else if (viewId == R.id.button2) {
        Toast.makeText(this, "Button 2 clicked", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(this, "ListView clicked" + id, Toast.LENGTH_SHORT).show();
    }
}

Enjoy!...

It shouldn't be a problem to show a dialog from the adapter. If your adapter needs something that it doesn't have, then you can add a field for your adapter with some listener like private final OnImageClickListener and create an interface:

public interface OnImageClickListener {
    void onImageClicked(View view, int position, int id);
}

When you create the adapter from your activity or a fragment, you can implement this interface either in your activity/fragment or inside an anonymous class, and in there you have access to the fragment manager and can do whatever you want.
