    <p>i'm trying to extend an HorizontalScrollView with a RadioGroup inside, when i populate the radiogroup all the button become selected on click, instead only the one i clicked</p> <pre><code>this is my class: package widgets; import java.util.ArrayList; import android.annotation.SuppressLint; import android.content.Context; import android.graphics.drawable.Drawable; import android.graphics.drawable.StateListDrawable; import android.util.AttributeSet; import android.widget.CompoundButton; import android.widget.HorizontalScrollView; import android.widget.RadioButton; import android.widget.RadioGroup; import android.widget.RadioGroup.OnCheckedChangeListener; public class HorizontalListView extends HorizontalScrollView { ArrayList&lt;String&gt; lista = new ArrayList&lt;String&gt;(); ArrayList&lt;RadioButton&gt; listaButton = new ArrayList&lt;RadioButton&gt;(); int selected = -1; Drawable itemSelector; Context context; android.widget.CompoundButton.OnCheckedChangeListener listener; RadioGroup group; public HorizontalListView(Context context, AttributeSet attrs) { super(context, attrs); this.context = context; initView(); } public HorizontalListView(Context context, ArrayList&lt;String&gt; stringhe, Drawable itemBackground) { super(context); this.context = context; this.lista = stringhe; this.itemSelector = itemBackground; initView(); } @SuppressLint("NewApi") private synchronized void initView() { this.removeAllViews(); group = new RadioGroup(getContext()); group.setOrientation(RadioGroup.HORIZONTAL); LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT); this.addView(group, params); int i = 0; for (String string : lista) { RadioButton button = new RadioButton(getContext()); if (android.os.Build.VERSION.SDK_INT &lt; android.os.Build.VERSION_CODES.JELLY_BEAN) { button.setBackgroundDrawable(itemSelector); } else { button.setBackground(itemSelector); } button.setButtonDrawable(new StateListDrawable()); button.setText(string); button.setTag(i); LayoutParams paramsButton = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT); button.setPadding(20, 0, 20, 0); listaButton.add(button); group.addView(button, paramsButton); i++; } } </code></pre> <p>and this is my selector, i made all the state i need to select the correct one, but as i said the radiogroup select all the items (they also become selected if i scroll the horizontalscrollview)</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_checked="true" android:state_pressed="false"&gt;&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;stroke android:width="1dp" android:color="@color/sinottica_button_border" /&gt; &lt;solid android:color="@color/sinottica_button_bg_selected" /&gt; &lt;padding android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="2dp" /&gt; &lt;/shape&gt;&lt;/item&gt; &lt;item android:state_checked="false" android:state_pressed="false"&gt;&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;stroke android:width="1dp" android:color="@color/sinottica_button_border" /&gt; &lt;solid android:color="@color/sinottica_button_bg" /&gt; &lt;padding android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="2dp" /&gt; &lt;/shape&gt;&lt;/item&gt; &lt;item android:state_checked="true" android:state_pressed="true"&gt;&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;stroke android:width="1dp" android:color="@color/sinottica_button_border" /&gt; &lt;solid android:color="@color/sinottica_button_bg_selected" /&gt; &lt;padding android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="2dp" /&gt; &lt;/shape&gt;&lt;/item&gt; &lt;item android:state_checked="false" android:state_pressed="true"&gt;&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;stroke android:width="1dp" android:color="@color/sinottica_button_border" /&gt; &lt;solid android:color="@color/sinottica_button_bg" /&gt; &lt;padding android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="2dp" /&gt; &lt;/shape&gt;&lt;/item&gt; &lt;/selector&gt; </code></pre> <p>UPDATE:</p> <p>i tried to not remove the StateListDrawable, so i commented this row </p> <pre><code> button.setButtonDrawable(new StateListDrawable()); </code></pre> <p>now i have the checkbox over my textview, but while the background is out of sync with the selection, (change when i scroll, the other radiobutton in the group change their selection state when i touch one button) the checkmark is correct... there is a way to put the statelist drawable as background for the Button instead of the default (on the left of the button)</p>

    1. COCan you show how you instantiate your selector as a drawable? I don't see any issues in the above code. Although when creating padding in code, I would multiply the values by the screen density so you're working in density-independent units instead of pixels.

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).
