Displayutil

The system provides a method for converting to PX:

  /*** Replace the SP value with the PX value to ensure the text is not changed * *@paramContext *@paramSpvalue *@return     */     Public Static intSP2PX (Context context,floatspvalue) {        return(int) typedvalue.applydimension (typedvalue.complex_unit_sp, Spvalue, Context.getresources (). GetDisplayMetrics ()); }    /*** Change the dip to PX to ensure the size is unchanged * *@paramContext *@paramDipvalue *@return     */     Public Static intDIP2PX (Context context,floatdipvalue) {        return(int) typedvalue.applydimension (Typedvalue.complex_unit_dip, Dipvalue, Context.getresources (). GetDisplayMetrics (    )); }
