資源簡介
當(dāng)我們?cè)谔幚硐螺d或是其他需要長時(shí)間執(zhí)行的任務(wù)時(shí)，如果直接把處理函數(shù)放Activity的OnCreate或是OnStart中，會(huì)導(dǎo)致執(zhí)行過程中整個(gè)Activity無響應(yīng)，如果時(shí)間過長，程序還會(huì)掛掉。Handler就是把這些功能放到一個(gè)單獨(dú)的線程里執(zhí)行，與Activity互不影響。當(dāng)用戶點(diǎn)擊一個(gè)按鈕時(shí)如果執(zhí)行的是一個(gè)常耗時(shí)操作的話，處理不好會(huì)導(dǎo)致系統(tǒng)假死，用戶體驗(yàn)很差，而Android則更進(jìn)一步，如果任意一個(gè)Acitivity沒有響應(yīng)5秒鐘以上就會(huì)被強(qiáng)制關(guān)閉，因此我們需要另外起動(dòng)一個(gè)線程來處理長耗時(shí)操作，而主線程則不受其影響，在耗時(shí)操作完結(jié)發(fā)送消息給主線程，主線程再做相應(yīng)處理。那么線程之間的消息傳
