    <p>So, I've got this code for an AlertDialog in an Android activity, and although it works and pops up at the correct moment, when I press the "OK" buttons it's supposed to save the 2 variables which I put in, into 2 Strings which after the activity should be able to use those strings. </p> <pre><code>private void showDialog(){ AlertDialog.Builder alertdg = new AlertDialog.Builder(this); alertdg.setTitle("Choose page"); alertdg.setMessage("Choose episode/page"); final EditText page = new EditText(this); final EditText episode = new EditText(this); page.setWidth(210); episode.setWidth(210); LinearLayout layout = new LinearLayout(this); layout.addView(episode); layout.addView(page); alertdg.setView(layout); alertdg.setPositiveButton("Ok", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub episodeString = episode.getText().toString(); pageString = page.getText().toString(); } }); alertdg.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub } }); alertdg.show(); } </code></pre> <p>And yes if you're wondering I already declared the 2 strings "episodeString" and "pageString" somewhere in the start of the activity, and I know I declared them correctly. Now what I'm wondering is, why can't I return those values so that the rest of the activity can use them? I've tried many times but the Dialog just won't return/save values... What am I doing wrong?</p>

    1. COHave you debug this portion of code? if yes have you printed the values after onClick. i am assuming there is problem in OnClick only

    2. COWell you are doing everything right. So technically your code should work. Can you tell me how / when you are accessing those variables, and where exactly have you defined them. And like @Drax said, try logging the values in the onClickListener , make sure you are getting the values there atleast.

    3. COI think i know what you are trying to do, Are you trying to use those Variables as soon as you call `showDialog`? See, the variables are filled with values ONLY after the OK button is pushed, until then they are empty. I hope this solves this.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
