How to add a new object to Layout by Java? Android

Question

For example, I have an ImageView got by this:

public ImageView get_image_by_name(String name)
{
    int image_id = getResources().getIdentifier(name , "drawable", getPackageName());
    return (ImageView)findViewById(image_id);
}

Not sure it works at all.

How shall I add it to layout?

Answer 1

Assuming this function is placed somewhere within Activity, you can try this:

public ImageView get_image_by_name(String name)
{
    int image_id = getResources().getIdentifier(name , "drawable", getPackageName());
    ImageView iv = new ImageView(this);
    ViewGroup.LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    iv.setLayoutParams(lp);
    iv.setImageDrawable(getResources().getDrawable(image_id));
    return iv;
}

You can also change LayoutParams to meet your requirements.
