    <p>I understand that there is this documentation</p> <p><a href="http://developer.android.com/reference/android/app/DialogFragment.html#AlertDialog">http://developer.android.com/reference/android/app/DialogFragment.html#AlertDialog</a></p> <p>but as a new Android/Java learner it is not easy to understand the amount of code involved from writing a simple alert dialog that pops up with 2 options (yes/no) message.</p> <p>Here is the code I currently have in my MainActivity file:</p> <pre><code>final private int RESET_DIALOG = 0; private OnClickListener resetButtonListener = new OnClickListener() { @Override public void onClick(View v) { showDialog(RESET_DIALOG); } }; protected android.app.Dialog onCreateDialog(int id) { switch(id) { case RESET_DIALOG: AlertDialog.Builder builder = new Builder(this); return builder .setMessage("Are you sure you want to reset the count?") .setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { Toast.makeText(MainActivity.this, "Did not reset!", 5).show(); } }) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { Toast.makeText(MainActivity.this, "Did Reset!", 5).show(); } }) .create(); } return null; }; </code></pre> <p>This is my attempt to following the instructions on the android site: Main Activity file:</p> <pre><code>final private int RESET_DIALOG = 0; private OnClickListener resetButtonListener = new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(MainActivity.this, MainDialog.class); startActivity(intent); } }; protected android.app.Dialog onCreateDialog(int id) { switch(id) { case RESET_DIALOG: AlertDialog.Builder builder = new Builder(this); return builder .setMessage("Are you sure you want to reset the count?") .setNegativeButton("No", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { Toast.makeText(MainActivity.this, "Did not reset!", 5).show(); } }) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { Toast.makeText(MainActivity.this, "Did Reset!", 5).show(); } }) .create(); } return null; }; </code></pre> <p>Then created a MainDialog class: (I am actually lost in how to do this correctly or apply it)</p> <pre><code>package com.proteintracker; import android.support.v4.app.DialogFragment; public class MainDialog extends DialogFragment { public static MyAlertDialogFragment newInstance(int title) { MyAlertDialogFragment frag = new MyAlertDialogFragment(); Bundle args = new Bundle(); args.putInt("title", title); frag.setArguments(args); return frag; } } </code></pre> <p>I am not sure if I was suppose to create a new class for the fragment and how to apply it to my current dialog in the activity screen.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
