背景

其實程序猿要開發(fā)一個demo的背景，都！一！樣！
說什么為了社會進(jìn)步，為了挑戰(zhàn)自我，都！是！瞎！扯！蛋！
無非就是一個背景，產(chǎn)品經(jīng)理要求實現(xiàn)該功能?。?！

生無可戀

廢話小說，先上gif為敬！

這是一個gif動態(tài)圖

功能

沒什么好說的，用上最新版微信，打開“位置”---“發(fā)送位置”，萌萌噠，感覺一個樣子有木有，相似度99.99%不是夢

還是循例說一下：

• 定位
• 定位數(shù)據(jù)地圖標(biāo)志并列表顯示
• 移動地圖獲取最新位置信息并顯示
• 提供搜索關(guān)鍵字功能
• 一鍵發(fā)送獲取具體地址信息經(jīng)緯度什么的
• ！@#￥%…………&&**（）

步驟

前期準(zhǔn)備

去高德地圖開發(fā)中心，注冊賬號，申請key，下載jar包！@#￥%……&*（）
（順便吐槽一下高德的文檔看的真讓人蛋！痛?。?/p>

GPS定位

• 使用高德定位獲取AMapLocation數(shù)據(jù)
• 將地圖使用動態(tài)般絲滑移動到定位數(shù)據(jù)頁面顯示
• 繪制出GPS定位到的Marker標(biāo)記
• 使用PoiSearch將定位附近地標(biāo)信息獲取并顯示在RecycleView當(dāng)中去

移動地圖畫布

• 為綁定的AMap添加OnCameraChangeListener監(jiān)聽器
• 移動結(jié)束后，來一波Marker標(biāo)記圖案動畫
• 利用GeocodeSearch將經(jīng)緯度逆地址編碼變成PoiItem的文字信息
• 將PoiItem顯示在RecycleView當(dāng)中去

貌似看起來也不難吧

這是一只生無可戀的狗
