【正文】 and WiFi in public places is more and more popular, with function of work munication for the mainstream mobile devices including smartphones have everywhere, the Android system as the most popular mobile operating system, open the strongest brought new application to the user experience, and also brought new development opportunities for mobile software developers, more and more application software based on Android article is to rely on Android for studying the development and related technology. This system uses JAVA and Android SDK (Software Development Kit) Development, including the Android SDK is mainly based on JAVA language, includes a mobile application on the Android platform Development set of can use the Java language to develop software applications on the Android the Eclipse ADT + (Android Development Tools) as a Development tool, the Android emulator with Android mobile phone real machine test image reader design USES the modular approach, the same module implements the high cohesion, realized the low coupling between different whole system is divided into different functional modules, the installation of different function modules, detailed design, coding and development. Design and the implementation of the image of the reader, in a simulator experiment, has achieved fairly good results, good performance in all implement the scanned picture of SD card。較好的實現(xiàn)了對 SD 卡上的圖片進(jìn)行掃描顯示；在放縮圖片、旋轉(zhuǎn)圖片、刪除圖片以及圖片詳細(xì)信息的獲取等方面取得了不小的進(jìn)步。把整個系統(tǒng)劃分為不同的功能模塊，安裝不同的功能模塊，進(jìn) 行詳細(xì)設(shè)計，然后進(jìn)行編碼開發(fā)。采用 Eclipse + ADT（ Android Development Tools）作為開發(fā)工具，在 Android 手機(jī)模擬器和 Android 手機(jī)真機(jī)上測試運(yùn)行。 本系統(tǒng)使用 JAVA 和 Android SDK（ Software Development Kit）開發(fā)，其中 Android SDK 主要是以 Java 語言為基礎(chǔ)，包含了在 Android 平臺上開發(fā)移動應(yīng)用的各種工具集。找畢業(yè)設(shè)計、項目源碼、編程視頻，就上碼農(nóng)網(wǎng) manong365 基于 Android 的圖片閱讀器的設(shè)計與實現(xiàn) 摘 要 隨著 4G 時代的到來以及公共場所 WiFi 越來越普及，以網(wǎng)絡(luò)通信為主流功能的移動終端設(shè)備包括智能手機(jī)已經(jīng)隨處可見，而 Android 系統(tǒng)作為最流行、開放性最強(qiáng)的手機(jī)操作系統(tǒng)給用戶帶來了新的應(yīng)用體驗，也給移動軟件開發(fā)者帶來了新的發(fā)展機(jī)會，以 Android 為平臺的應(yīng)用程序軟件越來越多。本文即是依靠 Android 有關(guān)的技術(shù)來進(jìn)行開發(fā)和研究。用戶可以使用 Java 語言來開發(fā) Android 平臺上的軟件應(yīng)用。該圖片閱讀器的設(shè)計使用了模塊化的方法，同一模塊實現(xiàn)了高內(nèi)聚，不同模塊之間實現(xiàn)了低耦合。 該圖像閱讀器的設(shè)計和實現(xiàn)，在模擬器的實驗中，取得了比較不錯的結(jié)果，各方面性能表現(xiàn)良好。這些都表明本文的工作是有意義的。In scale, rotating pictures, delete pictures and images detailed information retrieval has made big this suggests that the work of this paper is meaningful.
