Android - TextView textStyle 没有改变

Question

我想根据我得到的数据将 TextView 样式从粗体切换为正常。

我这样做：

reserveCount.setText("Reservations " + reservationCount);
if(reservationCount<20){
  Log.i("reserveCount", "typeface: NORMAL");
  reserveCount.setTypeface(reserveCount.getTypeface(), Typeface.NORMAL);
} else {
  Log.i("reserveCount", "typeface: BOLD");
  reserveCount.setTypeface(reserveCount.getTypeface(), Typeface.BOLD);
}

但是风格根本没有改变（它一直保持大胆）。

Answer 1

尝试在最后调用

reserveCount.invalidate()

或

reserveCount.requestLayout()

强制重画

View

Answer 2

尝试一下

reserveCount.setText("Reservations " + reservationCount);  
if(reservationCount<20){
  Log.i("reserveCount", "typeface: NORMAL"); 
  reserveCount.setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));
} else {
  Log.i("reserveCount", "typeface: BOLD");  
  reserveCount.setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));  
}
