    <p>In my code, If we need particular number of checkbox or radio button, by giving the count value in EditText, we can get the particular number of checkbox. But It is displaying the checkbox with random alphabets from a to z. But, I need it to change/rename specifically based on my need. Your help is highly appreciated. Thanks in advance. Here is my code.</p> <p>XML Layout:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" &gt; &lt;EditText android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="12dp" android:layout_marginTop="05dp" android:hint="Enter Text" /&gt; &lt;Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/button1" android:layout_alignBottom="@+id/button1" android:layout_alignParentRight="true" android:layout_marginRight="05dp" android:text="Edit Text" /&gt; &lt;Button android:id="@+id/button4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_below="@+id/button2" android:text="Check Box" /&gt; &lt;Button android:id="@+id/button5" android:layout_width="98dp" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_below="@+id/button4" android:text="Radio Button" /&gt; &lt;EditText android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/button4" android:layout_alignParentLeft="true" android:hint="Enter no" /&gt;

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).
