Switch Control in ListView gets UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

Question

I'm creating an android application that will control certain domestic devices such as bulbs. The task of this application is simply to enable the device to turn on and turn off as long as it is connected with my bluetooth module which I'm currently using a HC-05 model.

Everything works fine already. It can now control different devices. The problem is when I want to improve the UI of my app in my controller tab (i'm using 1 tabs in the app) its having an error. Suppose to be I'll be having my 3 switch controls inside a ListView but when I implemented it already I'm having these trouble in my LogCat:

I'm probably sure its in my activity_main.xml where my switch controls are located in which it went wrong. These are my codes in this file:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Switch
        android:id="@+id/switch1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/digitalClock1"
        android:layout_marginBottom="15dp"
        android:text="@string/switch1" />

    <Switch

        android:layout_marginBottom="15dp"
        android:text="@string/switch3" />

    <DigitalClock
        android:id="@+id/digitalClock1"

        android:layout_marginTop="0dp"
        android:layout_marginBottom="5dp"

    <ListView

        android:layout_width="match_parent"
        android:layout_height="wrap_content"

        android:layout_below="@+id/switch3"
        android:layout_marginTop="22dp" >

        <RelativeLayout
        android:id="@+id/groupSub"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >

            <Switch
            android:id="@+id/switch4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="15dp"
            android:text="@string/switch1" />

            <Switch
            android:id="@+id/switch5"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="15dp"
            android:text="@string/switch2" />

        </RelativeLayout>

    </ListView>

</RelativeLayout>

I noticed also that there's a problem with my java file in my class ControllerTab since this error appear in the LogCat: 01-17 23:11:16.662: E/AndroidRuntime(4929): at com.example.javac101.ControllerTab.onCreate(ControllerTab.java:87) But when I check this line its only this code: setContentView(R.layout.activity_main);

Any help will be so much appreciated in for this project. You will really be a big help for this one. Thank you in advance to those who will comment for some help. I already did my best as a beginner.

Answer 1

Please remove the child elements from <ListView> in your layout, as that is not how you use a ListView.

To populate a ListView, you create a ListAdapter, such as an ArrayAdapter, and attach that adapter to the ListView:
