Just use a LinearLayout and pretend it’s a Button – setting background and clickable is the key:

<LinearLayout
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@android:drawable/btn_default"
    android:clickable="true"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="5dp"
        android:src="@drawable/image" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_margin="5dp"
        android:text="Do stuff" />
</LinearLayout>

In this method just current activity receive this event
Add to android Manifest

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

In your activity, create a Broadcast Receiver:

private BroadcastReceiver networkStateReceiver=new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo ni = manager.getActiveNetworkInfo();
        doSomethingOnNetworkChange(ni);
    }
};

@Override
public void onResume() {
    super.onResume();
    registerReceiver(networkStateReceiver, new IntentFilter(android.net.ConnectivityManager.CONNECTIVITY_ACTION));
}

@Override
public void onPause() {
    unregisterReceiver(networkStateReceiver);
    super.onPause();
}

For < Android Nougat:

myTextView.setText(Html.fromHtml("<h2>Title</h2><br><p>Description here</p>"));

For >= Android Nougat:

myTextView.setText(Html.fromHtml("<h2>Title</h2><br><p>Description here</p>", Html.FROM_HTML_MODE_COMPACT));

To distinguish between Android versions use Build.VERSION.SDK_INT >= Build.VERSION_CODES.N.
