2、以很好的解決這個(gè)問(wèn)題。而且軟件操作界面簡(jiǎn)潔，操作容易上手。任何人都可以使用，沒(méi)有技術(shù)門(mén)檻。1.3 流程圖1.4 使用環(huán)境(1) 黑暗環(huán)境(2) 需要屏幕燈光的環(huán)境(3) 需要警示燈，警燈，SOS求救信號(hào)的環(huán)境第二部分 軟件功能介紹2.1 打開(kāi)軟件打開(kāi)軟件后，就會(huì)出現(xiàn)下面的主界面。 主界面很簡(jiǎn)潔，上面部分是軟件的名字，中間部分是顯示電量，往下在屏幕的中央是開(kāi)關(guān)按鈕，再往下有一個(gè)框，如果在框中打鉤的話(huà)，每次啟動(dòng)軟件后會(huì)自動(dòng)打開(kāi)閃關(guān)燈。最下面是五個(gè)按鈕。左側(cè)四個(gè)是功能按鈕，不同圖標(biāo)對(duì)應(yīng)著各自的功能，從左至右依次為屏幕燈光，警示燈，警燈，SOS求救信號(hào)。用戶(hù)可通過(guò)點(diǎn)按圖標(biāo)打開(kāi)對(duì)應(yīng)功能，操作十分簡(jiǎn)便。具

3、體功能及其操作詳見(jiàn)2.2-2.4。2.2 屏幕燈光點(diǎn)擊屏幕燈光按鈕時(shí)會(huì)出現(xiàn)下面的界面屏幕最下面是各種顏色的按鈕，例如點(diǎn)擊藍(lán)色就會(huì)出現(xiàn)藍(lán)色的界面。一共可以顯示八種顏色，點(diǎn)擊不同顏色按鈕，屏幕就會(huì)出現(xiàn)相應(yīng)的顏色界面。 2.3 警示燈點(diǎn)擊該按鈕后·會(huì)出現(xiàn)警示燈界面上下兩個(gè)燈可以輪流閃亮，在特定的情況下可以起到一定的警示作用。2.4 警燈打開(kāi)此按鈕，會(huì)出現(xiàn)紅色和藍(lán)色交替閃爍的界面，以模仿警燈。2.5 SOS求救信號(hào)。點(diǎn)擊此按鈕，會(huì)出現(xiàn)紅色閃爍的界面。此功能為某些特殊的情況尤其在危急情況下而設(shè)計(jì)，必要的時(shí)候可用來(lái)求救以脫離險(xiǎn)境。第三部分 注意事項(xiàng)3.1 使用注意長(zhǎng)時(shí)間使用會(huì)導(dǎo)致電量消耗過(guò)快，而

4、且可能會(huì)對(duì)閃關(guān)燈造成損害，請(qǐng)注意使用時(shí)間，注意合理使用。 3.2 源代碼package com.flashlightfree;import java.io.IOException;import java.util.List;import java.util.Random;import com.flashlightfree.R;import com.google.ads.AdRequest;import com.google.ads.AdSize;import com.google.ads.AdView;import android.media.AudioManager;import andro
