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>"));
}

Answer 1

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>"));
