Question

I have a linear layout which I fill with imageviews everytime the user takes a picture with the camera. So these imageviews are added dynamically.

To each of these imageviews I attached an OnClick event to open the picture and show it in another imageview in another activity.

Each imageview has a tag containing an arraylist item with the bitmap information.

The OnClick event:

ImageView iv = new ImageView(this);
LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,     LinearLayout.LayoutParams.WRAP_CONTENT);
iv.setLayoutParams(params);
iv.setImageBitmap(mBitmap);
iv.setTag(pli);
iv.setPadding(5, 5, 5, 5);
lvp.setOnClickListener(new OnClickListener() {

public void onClick(View arg0) {
    PhotoList pli = (PhotoList) arg0.getTag();
    Intent i = new Intent(getBaseContext(), PhotoActivity.class);
    i.putExtra("photo", pli.Photo);
        i.putExtra("PhotoId", pli.id);
    startActivity(i);
}
});

lvp.addView(iv);

Obviously the line with arg0.getTag() is not working.
Variable arg0 is of the linearlayout, but I need the clicked on imageview.

How do I detect wich imageview in the linearlayout was clicked on?

Answer 1

You have set the OnClickListener to the parent LinearLayout instead of the ImageView.

Instead of this:

lvp.setOnClickListener(new OnClickListener() {

    public void onClick(View arg0) {
        ...
    }
});

Use this:

iv.setOnClickListener(new OnClickListener() {

    public void onClick(View arg0) {
        ...
    }
});
