Android

Question

我想根据获得的数据将 TextView 样式从粗体切换为普通。

我是这样做的：

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);
}

但是风格一点都没有变（一直都是粗体）。

Answer 1

试一试
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));
}

Answer 2

尝试在最后调用reserveCount.invalidate()或reserveCount.requestLayout()强制重绘View

Android - TextView textStyle 没有改变
