How to align TextView around an ImageView
We can achieve this by using the android.text.style.LeadingMarginSpan.LeadingMarginSpan2 interface which is available in API 8.
An extended version of LeadingMarginSpan, which allows the implementor to specify the number of lines of the paragraph to which this object is attached that the "first line of paragraph" margin width will be applied to.
There should only be one LeadingMarginSpan2 per paragraph. The leading margin line count affects all LeadingMarginSpans in the paragraph, adjusting the number of lines to which the first line margin is applied.
As with LeadingMarginSpans, LeadingMarginSpan2s should be attached from the beginning to the end of a paragraph.

Create Custom Leading Margin
class CustomLeadingMargin implements LeadingMarginSpan2 {
private int marginSpace;
private int numberOfLines;
CustomLeadingMargin(int numberOfLines, int marginSpace) {
this.numberOfLines = numberOfLines;
this.marginSpace = marginSpace;
}
@Override
public int getLeadingMargin(boolean firstLineFlag) {
return firstLineFlag ? marginSpace : 0;
}
@Override
public int getLeadingMarginLineCount() {
return numberOfLines;
}
@Override
public void drawLeadingMargin(Canvas c, Paint p, int x, int dir,
int top, int baseline, int bottom, CharSequence text,
int start, int end, boolean first, Layout layout) {}
}
Apply in the TextView
//Get the string from the String File
String descText = getString(R.string.description);
Drawable dIcon = getResources().getDrawable(R.drawable.icon);
int leftMargin = dIcon.getIntrinsicWidth() + 5;
ImageView icon = (ImageView) findViewById(R.id.startImage);
icon.setBackgroundDrawable(dIcon);
SpannableString mSpannableString = new SpannableString(descText);
ss.setSpan(new CustomLeadingMargin(3, leftMargin), 0, mSpannableString.length(), 0);
((TextView) findViewById(R.id.message_view)).setText(mSpannableString);

DeleteIt would seem like flash drives are old news by now. You put more and more memory into them and increase the price, and that’s about it, right?

Also, might I suggest using the RelativeLayout inside a ScrollView, such that it can accommodate large amounts of text inside the TextView.
