Question

I have created an Android RSS Reader App.I have a text marquee in my android app.Iam fetching RSS feed and store RSS title as an array.Iam setting this array as the marque text.Check the code,

String MarqueeStr="";
TextView flashnews;

for (int i = 0; i < nl.getLength(); i++) {

    MarqueeStr = MarqueeStr +" | "+ Headlines.Title[i];
        }

           flashnews.setText(MarqueeStr);

Now I have to set an onclick listener for my marquee, so that user can view detailed description of title which they are clicked.I know how to set it.But my problem is, how can i get the array index of clicked string in the marquee text when a user click on the marquee?

here is my XML layout,

<TextView
  android:id="@+id/flashs"
  android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:lines="1"
    android:ellipsize="marquee"
    android:layout_marginLeft="70dp"
    android:fadingEdge="horizontal"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="true"
    android:singleLine="true"
    android:textColor="#e7e7e7" />

screen shote here..

I think that will only be possible if you will create your textviews dynamically and set id for them. like if you are having 10 news link then use 10 textviews

        TextView txt = null;
        View.OnClickListener marquee_click = new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                int selected_item = v.getTag();
                switch (selected_item) {
                case 0:

                    break;
                case 1:

                    break;
                case 2:

                    break;
                default:
                    break;
                }
            }
        };


        LinearLayout news_text_layout = new LinearLayout(getApplicationContext());
        news_text_layout.setOrientation(LinearLayout.HORIZONTAL);

        for (int i = 0; i < 10; i++) {
            txt = new TextView(getApplicationContext());
            txt.setTag(i);   // OR txt.setId(i);
            txt.setText("new " + i);
            txt.setOnClickListener(marquee_click);
            news_text_layout.addView(txt);
        }
        // ADD YOUR LINEAR LAYOUT ON WHICH YOU HAVE ADDED ALL TEXT VIEW IN YOUR LISTVIEW FOOTER.
        // NOW PERFORM SAME ANIMATION OR TRICK ON LINEAR LAYOUT WHICH YOU WERE PERFORMING ON marquee text.

Hope it can help you…
