Question

MY code is

 Paint paint= new Paint();
 paint.setTextSize(size); 
 int iRet = 0; 
 if (str != null && str.length() > 0) {
     int len = str.length(); 
     float[] widths = new float[len]; 
     paint.getTextWidths(str, widths); 
     for (int j = 0; j < len; j++) {
     iRet += (int) Math.ceil(widths[j]); 
    } 
}
 return iRet;

I want to get the width of string ,but the return result has errors with TextView.

Don’t know the right way.

thanks.

I show it in the virtual machine.

Answer 1

you can try to use canvas,Once a time I found the Textview can’t show my text in right size ,so I use Canvas draw the text out ,the I get the width I want,that’s maybe some wrong cause by dp,sp or px.
