目錄(?)[+]
1.需求
在Android應(yīng)用中打開百度地圖或者高德地圖進(jìn)行路線規(guī)劃，如果沒有安裝則打開網(wǎng)頁百度地圖進(jìn)行路線規(guī)劃。
2.API
2.1 打開百度地圖應(yīng)用
地址：http://lbsyun.baidu.com/index.php?title=uri/api/android
打開文檔可以看到功能還是很多的，這里只介紹 公交、駕車、導(dǎo)航、步行和騎行導(dǎo)航
這里寫圖片描述
注：必選項一定要填
2.2 打開瀏覽器并跳轉(zhuǎn)到網(wǎng)頁百度地圖
參數(shù)
這里寫圖片描述
2.3.打開高德地圖應(yīng)用
參數(shù)
這里寫圖片描述
3.使用

注：百度地圖和高德地圖使用的坐標(biāo)系不同，但是用上面兩個方法轉(zhuǎn)換的坐標(biāo)還是有問題。測試時把百度地圖定位的坐標(biāo)用上面的方法轉(zhuǎn)換成高德地圖的坐標(biāo)，然后在高德地圖網(wǎng)站對轉(zhuǎn)換后的坐標(biāo)進(jìn)行查找，能找到正確的位置，然而打開高德地圖app后提示位置不在支持范圍內(nèi)。幸運的是，高德地圖sdk中有相應(yīng)的工具類CoordinateConverter對坐標(biāo)進(jìn)行轉(zhuǎn)換。
