Android實(shí)現(xiàn)ping功能 ? Andriod實(shí)現(xiàn)ping功能，輸入需要ping的地址、ping的數(shù)據(jù)包個(gè)數(shù)和大小、以及每隔多久ping一次，ping功能比較耗時(shí)，所以在開啟的子線程中進(jìn)行，然后把ping結(jié)果發(fā)送到主線程中更新Textview顯示結(jié)果。對(duì)結(jié)果可以有兩種操作，一是復(fù)制，二是保存到本地SD卡中，方便以后查看。 ? 資源可以從http://download.csdn.net/detail/offerfinder/8903779免費(fèi)下載，下面是效果圖： 主界面：
