Question

Can anyone please guide me on how to setOnClickListener for the TextViews that are generated dynamically.
I have few buttons in my app.Now when a particular button is clicked than some specific text elements are retrieved from the database based on the the number of elements returned corresponding TextViews are generated in order to display the retrieved text elements.
Now the problem that i’m having is that i don’t know how to set onClickListner for the dynamically generated TextViews.Following is the piece of code where i’m creating my TextViews.Please guide me on what should i do.thank you

public void onClick(View v) {
    switch (v.getId()) {
    case R.id.imageButton1:
catagory = "General";
            IndependentDB genData = IndependentDB.getInstance();
            genData.open(this);
            ArrayList<TextHolder> genList = new ArrayList<TextHolder>();
            genList = genData.getAllTextFromGenT();
            genData.close();
            x = genList.size();
            String xstr = new StringBuilder().append(x).toString();
            System.out.println(xstr);
            mainText = new TextView[x];
            textLayout = new LinearLayout[x];
            llseperator = new LinearLayout[x];
            textLayoutContainer
                    .setBackgroundResource(R.color.dark_navy_blue);
            if (!genList.isEmpty()) {
                for (int i = 0; i < x; i++) {
                    TextHolder firstOne = genList.get(i);
                    String text = firstOne.getText();
                    mainText[i] = new TextView(this);
                    mainText[i].setId(i);
                    mainText[i].setText("Text");
                    mainText[i].setLayoutParams(new LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT));
                    mainText[i].setTextSize(25);
                    mainText[i].setGravity(Gravity.CENTER);
                    mainText[i].setText(text);
                    mainText[i].setTextColor(0xFFFFFFFF);
                    mainText[i].setClickable(true);
                    mainText[i].setOnClickListener(this);
                    llseperator[i] = new LinearLayout(this);
                    llseperator[i].setId(i);
                    llseperator[i].setLayoutParams(new LayoutParams(
                            LayoutParams.FILL_PARENT,
                            LayoutParams.WRAP_CONTENT));
                    llseperator[i].setGravity(Gravity.CENTER);
                    llseperator[i]
                            .setBackgroundResource(R.drawable.tv_seperator);

                    textLayout[i] = new LinearLayout(this);
                    textLayout[i].setId(i);
                    textLayout[i].setLayoutParams(new LayoutParams(

                    textLayout[i].setGravity(Gravity.CENTER);
                    textLayout[i].addView(mainText[i]);
                    textLayoutContainer.addView(textLayout[i]);
                    textLayoutContainer.addView(llseperator[i]);
                }// End of for
                }// End of If

You already have onClick() method in Activity class (implemented View.setOnClickListener) so I suggest you to create a new class which implements View.setOnClickListener interface to handle click of TextView.

Try,

class TextClick implements View.setOnClickListener {
  @Override
  public void onClick(View view) {
     TextView tx=(TextView) view;
     ...
   }
}

and set click listener,

 TextClick click=new TextClick();
 for (int i = 0; i < x; i++) {
    TextHolder firstOne = genList.get(i);
    String text = firstOne.getText();
    mainText[i] = new TextView(this);      
    mainText[i].setOnClickListener(click);
    ...
 }
