    copied!<p>My app is about creating surveys. In order to do so, the user should be able to create new fields dynamically.</p> <p>So, when creating a new survey, an Activity is shown with only 2 buttons (add and delete). When a user clicks the add button, a row appears containing a EditText(so he can write the question), a Spinner(that enables user to select the type of field: text, RadioButton, CheckBox, etc..) and another EditText (in which the different available answer choices are written, if applicable).</p> <p>To accomplish this I created a XML file containing these Widgets and each time the user clicks in the add button, the XML is inflated. It works the first time I press the button, but after that... nothing happens.</p> <p>I read somewhere that you cannot inflate the same child 2 times in a parent unless it is done in a loop.</p> <p>So, my questions are:</p> <p>-> How can I get around this and obtain the desired effect?</p> <p>-> Why doesn't this apply in a Loop?</p> <p>Any help or hint is appreciated. Once again, thank you very much for all the support the community has given me.</p> <p>NOTE: In the android documentation they speak about cloning an inflator but the information there is scarce and I couldn't find any other info about it.</p> <p>SOurce code:</p> <p>XML - Main cointainer:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;LinearLayout android:id="@+id/wrapper" android:layout_width="fill_parent" android:layout_height="wrap_content" /&gt; &lt;Button android:id="@+id/mds_new_addfield_button" android:tag="new" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add Field" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" /&gt; &lt;Button android:id="@+id/mds_new_deletefield_button" android:tag="delete" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Delete Field" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>XML -Inflated:</p> <pre><code>&lt;TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" &gt; &lt;TableRow&gt; &lt;TextView android:id="@+id/mdsnew_field_tv" style="@style/dsn_field" android:text="Field Name " /&gt; &lt;TextView android:id="@+id/mdsnew_type_tv" style="@style/dsn_field" android:text="Type of Field " /&gt; &lt;TextView android:id="@+id/mdsnew_choices_tv" style="@style/dsn_field" android:text="Choices" /&gt; &lt;/TableRow&gt; &lt;TableRow&gt; &lt;EditText android:id="@+id/mdsnew_fieldname_et" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Field Name" android:textSize="18sp" /&gt; &lt;Spinner android:id="@+id/mdsnew_type_sp" android:layout_width="wrap_content" android:layout_height="wrap_content" /&gt; &lt;EditText android:id="@+id/mdsnew_choices_et" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Choices " android:textSize="18sp" /&gt; &lt;/TableRow&gt; &lt;/TableLayout&gt; </code></pre> <p>Add Button:</p> <pre><code>LinearLayout myRoot = (LinearLayout) findViewById(R.id.wrapper); LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); inflater.inflate(R.layout.mds_new_row, myRoot); </code></pre>
