Puede haber un problema de falta de coincidencia de la hora actual en Android, simplemente configure la zona horaria para resolverlo
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
df.setTimeZone(TimeZone.getTimeZone("GMT+08:00"));
Obtenga la diferencia horaria entre la hora actual y una hora determinada

Agregue aquí donde sea necesario en la vista de texto para cambiar el color y el contenido
String time_group = getTime("2020-10-1 10:30:27" );
int[] time_array = handle_time(time_group);
GradientDrawable gd = (GradientDrawable) holder.tv_log_tag.getBackground();
gd.setColor(view.getResources().getColor(getColor(time_array[1])));
textview.setText(parse_time(time_array));
/*--------------------------------以下用于设置日志小标签2min前--------------------------------*/
private int[] handle_time(String input_time){
StringTokenizer fenxi = new StringTokenizer(input_time,"|");
int[] result = new int[2];
int i = 0;
while (fenxi.hasMoreTokens()){
result[i] = Integer.parseInt(fenxi.nextToken());
i++;
}
return result;
}
private String parse_time(int[] input_array){
String[] time_list = {
"年","月","天","小时","分钟","秒"};
if (input_array[1] == 5)
return "刚刚";
else
return ""+input_array[0]+time_list[input_array[1]]+"前";
}
private int getColor(int time_index){
int[] color = {
R.color.darkblue,R.color.red,R.color.search_opaque,R.color.orchid,R.color.medium_spring_green,R.color.medium_purple};
if (time_index>=0 && time_index<=5)
return color[time_index];
return color[0];
}
Finalmente, el fondo de la vista de texto en el diseño está representado por el xml en el directorio dibujable
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<!-- 设置圆角-->
<corners android:radius="8dp" />
<solid android:color="@color/blue"/>
</shape>
Tenga en cuenta que
el xml de fondo que usa textview no debe ser usado por otros controles, ya que afectará la visualización normal del fondo de otros controles.
