    <p>I am creating a custom dialog that will show the information of a food item: the xml layout for the dialog is</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout_root" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" &gt; &lt;TextView android:id="@+id/lblCal" android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; &lt;/TextView&gt; &lt;TextView android:id="@+id/lblFat" android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; &lt;/TextView&gt; &lt;TextView android:id="@+id/lblCarb" android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; &lt;/TextView&gt; &lt;TableRow android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; &lt;Button android:layout_width="wrap_content" android:text=" OK " android:id="@+id/btnOK" android:layout_height="wrap_content"&gt; &lt;/Button&gt; &lt;Button android:layout_width="wrap_content" android:text="Home" android:id="@+id/btnHome" android:layout_height="wrap_content"&gt; &lt;/Button&gt; &lt;/TableRow&gt; &lt;/LinearLayout&gt; </code></pre> <p>the onCreatDialog method is defined like this:</p> <pre><code>@Override protected Dialog onCreateDialog(int id) { Dialog d; switch (id) { case 0: d = new Dialog(this); d.setContentView(R.layout.result_dialog); d.setTitle(item); TextView lblEnergy = (TextView) d.findViewById(R.id.lblCal); lblEnergy.setText("Energy: "+ String.valueOf(cal)); TextView lblFat = (TextView) d.findViewById(R.id.lblCal); lblFat.setText("Fat: "+ String.valueOf(fat)); TextView lblCarbs = (TextView) d.findViewById(R.id.lblCal); lblCarbs.setText("Carbs: " + String.valueOf(carb)); Button ok = (Button) d.findViewById(R.id.btnOK); ok.setOnClickListener(i); Button home = (Button) d.findViewById(R.id.btnHome); home.setOnClickListener(i); break; default: d = null; } return d; } </code></pre> <p>but when I run the program the first two textview don't appear. </p> <p><strong>what is the problem?!!</strong></p> <p>what I should add to the ok button to close the dialog, because when I call DissmisDialog(0); when I click again on another item the dialog contents never changed</p>

    2. COAnother problem with your layout: you are using a TableRow just out of nowhere: "A TableRow should always be used as a child of a TableLayout"

Guidance
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).
