    <p>I've got an onCreateDialog method in my activity, which has a case switch to bring up different dialogs that I want to display depending on the request.</p> <p>I cannot use the showDialog() method from my view because it's not accessible from the context that is passed when the view is created. At least, I can't find a way to access it.</p> <p>How do I use showDialog from my application's view? Do I need to create a listener? And if so, how? Is there a better method?</p> <p>Here is my onCreateDialog code that exists in my application's activity:</p> <pre><code>protected Dialog onCreateDialog(int id) { AlertDialog alert=null; switch(id) { case DIALOG_GAMEOVER_ID: AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("You died. Play again?") .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //init(); //oGameState = eGameState.PLAYING; dialog.cancel(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { finish(); } }); alert = builder.create(); break; default: break; } return alert; } </code></pre> <p>I tried passing a reference to my activity, and I get crashes. Perhaps I am doing it wrong?</p> <p>In my activity:</p> <pre><code> // set our MainView as the View oNebulaMainView = new NebulaMainView(this, this); setContentView(oNebulaMainView); </code></pre> <p>In my view:</p> <pre><code>public NebulaMainView(Context context, Activity oActivity) { super(context); // adding the callback (this) to the surface holder to intercept events getHolder().addCallback(this); // create the game loop thread thread = new NebulaMainThread(getHolder(), this); setFocusable(true); oActivity.showDialog(DIALOG_GAMEOVER_ID); } </code></pre>

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.

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