Its quite simple as this:

txtView.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
      // TODO Auto-generated method stub
   }
});

Hope it helps.

it is very simple,do it like that:

TextView textView = (TextView) findViewById(R.id.yourtextview);
textView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // Codes for action
        }
    });

Updated Converting string into TextView?

TextView idText = new TextView(this);
    idText.setText(row.get(0).toString());
    tableRow.addView(idText);

    TextView storeText = new TextView(this);
    storeText.setText(row.get(1).toString());
    tableRow.addView(storeText);

    TextView maggiText = new TextView(this);
    maggiText.setText(row.get(2).toString());
    tableRow.addView(maggiText);

Thanks for your reply. In above i am adding only text to layout.how can i convert text into text view? — PRK449, Mar 14 '14 at 06:03

Set onclickListener to your TextView.

Just like this:-

TextView = textView (TextView) findViewById(R.id.TEXTVIEW_ID); 
textview.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

            }
        });

You can set ArrayList to ListView like this.

private ListView lv;

In onCreate method

lv = (ListView) findViewById(R.id.listView1);

change this line listItems.add(all.get(0)+" \n venue:"+all.get(1)+" Price:"+all.get(3)); like this.

listItems.add("ID"+all.get(0));
listItems.add("Venue"+all.get(1));
......................... etc

Then add to addapter

     ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
     this, 
     android.R.layout.simple_list_item_1,
     listItems );

     lv.setAdapter(arrayAdapter);

After that you can set OnItemClickListner like this

lv.setOnItemClickListener(new OnItemClickListener() {
 public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
            // Put your custom code here
        }
 });

Add this to activity_full_details.xml

<ListView
         android:id="@+id/listView1"
         android:layout_width="288dp"
         android:layout_height="330dp"
         android:layout_alignParentTop="true"
         android:layout_centerHorizontal="true"
         android:layout_marginTop="62dp" >
</ListView>

aha.. you are using ArrayList then you should add it into listView – anuruddhika Mar 14 '14 at 06:19
what do u want to display only one element or more elements? – anuruddhika Mar 14 '14 at 06:30
In present layout many elements.In another layout only one element after `onclick` of text – PRK449 Mar 14 '14 at 06:35
still showing error `java.lang.RuntimeException: Unable to start activity` i placed my full code updated above.I am getting error at ` lv.setAdapter(adapter);` – PRK449 Mar 14 '14 at 06:50
you should add ArrayAdapter arrayAdapter = new ArrayAdapter( this, android.R.layout.simple_list_item_1, listItems ); this befor the lv.setAdapter(arrayAdapter); – anuruddhika Mar 14 '14 at 06:54
did you add ListView to xml? – anuruddhika Mar 14 '14 at 06:55
already i used `ArrayAdapter adapter;` `adapter` in my `onCreate(Bundle icicle)` method so i used ` lv.setAdapter(adapter);`. No i have not added `listview` to xml – PRK449 Mar 14 '14 at 06:58
then how you add data to listView? – anuruddhika Mar 14 '14 at 07:06
i added xml code and change this lv = (ListView) findViewById(R.id.listView1); – anuruddhika Mar 14 '14 at 07:15
yes i mentioned `Listview` in `.xml` but still i am getting error. I mentioned my `activity_full_details.xml` above.showing same error `runtime exception` – PRK449 Mar 14 '14 at 07:18
i mentioned my log message in above – PRK449 Mar 14 '14 at 07:29
you added like this ne (android.R.layout.listView1); you should remove this android world.(R.layout.listView1); like this in onCreate – anuruddhika Mar 14 '14 at 08:03
