Issue in adding images dynamically to TextView

Below is my Activity Layout XML

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

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:bufferType="spannable"
    android:id="@+id/textView"
    android:text="@string/empty" />

</RelativeLayout>

and this below is the code which I use within my Activity

    TextView tView = (TextView) findViewById(R.id.textView);
    for(int i=0;i<15;i++){
    appendDrawable(tView,R.drawable.ic_launcher);
    appendText(tView,R.string.message);
    }

and the methods are :

private void appendDrawable(TextView tView, int drawableId) {
    SpannableStringBuilder builder = new SpannableStringBuilder();
    String THREE_SPACES = "   ";
    builder.append(THREE_SPACES);
    Drawable drawable = getResources().getDrawable(drawableId);
    drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
    ImageSpan image = new ImageSpan(drawable);      
    builder.setSpan(image, 1,  2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    tView.append(builder);  
}

private void appendText(TextView tView, int stringId) {
    tView.append(getResources().getString(stringId));
}

and the output which I got is not what I expected 3 missing output from Nexus

and if I tilt the screen 1 missing output from Nexus

Can anyone help me in finding out why the images went missing and if there is a better way of doing this.

Expected Output : As per the loop it should display (drawable, Hello World)15 times but in this example the drawable wasn't rendered thrice(and once when I tilted). Some issues with wrapping?

builder.setSpan(image, 1,  2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

should be

builder.setSpan(image, 0,  3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

since you're using 3 spaces as your span range
