Html.fromHtml not working

Question

I have a textview and I want to display 0.0 in normal fontSize of the TextView and then the StringResult() in a smaller text size.

If I add "0.0" + it's not working. Why?

public String StringResult(){
String displayLbl = this.getResources().getString(R.string.displayLbl);
TextView myUnitLbl = (TextView)findViewById(R.id.lbl_unit_res);
String myFinalLbl = displayLbl + " " + myUnitLbl.getText() + " ";
return myFinalLbl;
}


public void cmd_rst(View v){
TextView lblText = (TextView) findViewById(R.id.lblresult);
lblText.setText("0.0" + Html.fromHtml("<small>" + StringResult() + "</small>"));
}

lblText.setText(Html.fromHtml("<small>" + StringResult() + "</small>")); //only this works — dunrad

Thats because the Spanned returned from Html.fromHtml gets used as a normal String (thereby loosing any formatting) when you try to concatenate it with "0.0". To make this work, pass the whole stuff into fromHtml:

Html.fromHtml("0.0<small>" + StringResult() + "</small>")

The same principle applies in more complex cases:

lblResult.setText(Html.fromHtml(String.format("%.1f", myCalc) + " " + "<br>" +
    "<small>" + StringResult() + "</small>"));

YES. It was simple, thanks. But how about in this case more complex? lblResult.setText(String.format("%.1f", myCalc) + " " + "\n" + Html.fromHtml("<small>" + StringResult() + "</small>"));

Thanks Henry! It was pretty obvious that I had to include everything under Html.fromHtml() as you suggested. Works like a charm!!!

just

Html.fromHtml("0.0<small>" + StringResult() + "</small>")

changed to

Html.fromHtml("0.0<small>" + StringResult() + "</small>").toString()

Because fromHtml() method takes argument of Spanned type not String type.

Hmm, I don't get that. Html.fromHtml() returns a Spanned, if you call toString() on it the formatting will be lost.
