看到網上有很多 android:priority="2147483647" 這樣的取值，但是查看官方文檔發現 priority 的取值范圍是-1000 至 1000 。 對于 android:priority="2147483647" 的取值表示疑問，望各位解答，謝謝！官方文檔：The value must be an integer, such as "100". Higher numbers have a higher priority. The default value is 0. The value must be greater than -1000 and less than 1000.
