    <p>Sounds like a good opportunity to use an <a href="http://developer.android.com/reference/android/app/AlertDialog.html" rel="noreferrer">AlertDialog</a>.</p> <p>As basic as it seems, Android does not have a built-in dialog to do this (as far as I know). Fortunately, it's just a little extra work on top of creating a standard AlertDialog. You simply need to create an EditText for the user to input data, and set it as the view of the AlertDialog. You can customize the type of input allowed using <a href="http://developer.android.com/reference/android/widget/TextView.html#setInputType%28int%29" rel="noreferrer">setInputType</a>, if you need.</p> <p>If you're able to use a member variable, you can simply set the variable to the value of the EditText, and it will persist after the dialog has dismissed. If you can't use a member variable, you may need to use a listener to send the string value to the right place. (I can edit and elaborate more if this is what you need).</p> <p>Within your class:</p> <pre><code>private String m_Text = ""; </code></pre> <p>Within the OnClickListener of your button (or in a function called from there):</p> <pre><code>AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("Title"); // Set up the input final EditText input = new EditText(this); // Specify the type of input expected; this, for example, sets the input as a password, and will mask the text input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD); builder.setView(input); // Set up the buttons builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { m_Text = input.getText().toString(); } }); builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); builder.show(); </code></pre>

    1. COThe app seems to crash when I call "builder.show();". I get the following error message: "Can't create handler inside thread that has not called Looper.prepare();".

    2. COI've got a thread that constantly updates and renders a screen object, and I call the builder.show() method within the update method of the screen object.

    3. COOh. If you're on a worker thread, try putting the builder.show(); call with runOnUiThread, similar to this example: http://stackoverflow.com/a/3134720/1098302 Or maybe it would be better to put all the code above (that creates the AlertDialog) in a separate method, and call that method from within runOnUiThread.

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).
