How To Add Imageview's That Are Depending On The Text Of The Textview In A Listview

I have a custom ListView with a RowItem that contains TextView and a ImageView . The RowItems will be added dynamically. I just want to know how to add the ImageView to a specific

Solution 1:

You can make a switch-case statement based on the text of the TextView like below

switch(tv.getText().toString()){

                case"Title1" : image.setImageResource(R.drawable.ic_title1);
                    break;

                case"Title2" : image.setImageResource(R.drawable.ic_title2);
                    break;

                default:
                    //Default image here, if no case foundbreak;
}

Note: above answer requires JRE 1.7 compliance

The solution in this instance would be to add methods for getting and setting the individual fields for your ListView object. For example, since you have a TextView and an ImageView in your row item, let us assume that your row object looks something like the following:

publicclassListObject
{

    publicListObject (String textView, String imageView)
    {
        super();
        this.textView                      = textView;
        this.imageView                     = imageView;
    }

    privateString     textView;
    privateString     imageView;

    publicString getTextView ()
    {
        return textView;
    }

    publicvoid setTextView (String pTextView)
    {
        this.textView = pTextView;
    }

    publicString getImageView ()
    {
        return imageView;
    }

    publicvoid setImageView (String pImageView)
    {
        this.imageView = pImageView;
    }
}

Once these are implemented, you can easily set your ImageView based on your TextView like so:

// As an example, let us use the first list itemListObjectlistObject= (ListObject) parent.getItemAtPosition(0);

if (listObject.getTextView == "Title1")
{
    listObject.setImageView("NameOfResource");
}
// so on and so forth

Solution 3:

What about something like this.

image.setImageResource(getImageId(this, "ic_" + tv.getText().toString().toLowerCase());

So basically you're getting the title from the text view manipulating it to be in the format you're storing your images and calling the below helper to get the correct image id.

publicstatic int getImageId(Context context, String imageName) {
    return context.getResources().getIdentifier("drawable/" + imageName, null, context.getPackageName());
}
