Textview onclick() in widget android

Question

we have stored some text in an arraylist. we want to display it in a single textview,when I click the textview the next value(text) in the arraylist should be updated in the widget.

Could you post some code? What exactly is not working. This question provides some info on how to use onClick() in a widget http://stackoverflow.com/questions/9851000/change-icon-when-textview-is-clicked-in-widget — Lukas Ruge, Jul 03 '13 at 08:07

If I understand what you're trying to do correctly, try this out:

public class MyActivity extends Activity {
    ArrayList<String> values = new ArrayList<String>();
    TextView myText;
    private int index;
    protected void onCreate(Bundle saved) {
         super.onCreate(saved);

         setContentView(R.layout.content_layout_id);
         index = 0;

         //example values:
         values.add("foo");
         values.add("bar");
         values.add("another value");

         myText = (TextView) findViewById(R.id.myTextId);
         //show the first value on myText
         myText.setText(values.get(index));

         myText.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 // Show next value in our text view:
                myText.setText(values.get(++index));
                //be sure to consider the ArrayList.size() so you won't try to present the 6th value in a 5 values ArrayList.
                //but this depends on your implementation.
             }
         });
     }
 }
