1、判斷手機是否安裝地圖軟體

public static boolean isAvilible(Context context, String packageName){
    //獲取packagemanager
final PackageManager packageManager = context.getPackageManager();
    //獲取所有已安裝程式的包資訊
List<PackageInfo> packageInfos = packageManager.getInstalledPackages(0);
    //用於儲存所有已安裝程式的包名
List<String> packageNames = new 
 
ArrayList<String>();
    //從pinfo中將包名字逐一取出，壓入pName list中
if(packageInfos != null){
        for(int i = 0; i < packageInfos.size(); i++){
            String packName = packageInfos.get(i).packageName;
            packageNames.add(packName);
        }
    }
    //判斷packageNames中是否有目標程式的包名，有TRUE，沒有FALSE
 
return packageNames.contains(packageName);
}

2、根據地圖軟體進行導航

double  latitudes=0.0;
double  longitude=0.0;

  private  void  goDanghang(){
        Intent intent;
        if(isAvilible(SmallDetailActivity.this,"com.baidu.BaiduMap")){//傳入指定應用包名
//                          intent = Intent.getIntent("intent://map/direction?origin=latlng:34.264642646862,108.95108518068|name:我家&destination=大雁塔&mode=driving®ion=西安&src=yourCompanyName|yourAppName#Intent;scheme=bdapp;package=com.baidu.BaiduMap;end");
 
StringBuffer stringBuffer = new StringBuffer("baidumap://map/navi?location=")
                        .append(latitudes).append(",").append(longitude).append("&type=TIME");
                intent = new Intent(Intent.ACTION_VIEW, Uri.parse(stringBuffer.toString()));
                intent.setPackage("com.baidu.BaiduMap");
                startActivity(intent);

        }else if(isAvilible(SmallDetailActivity.this, "com.autonavi.minimap")){

                StringBuffer stringBuffer = new StringBuffer("androidamap://navi?sourceApplication=")
                        .append("yitu8_driver").append("&lat=").append(latitudes)
                        .append("&lon=").append(longitude)
                        .append("&dev=").append(1)
                        .append("&style=").append(0);
                ;
//        if (!TextUtils.isEmpty(poiname)) {
//            stringBuffer.append("&poiname=").append(poiname);
//        }
Intent intent1 = new Intent(Intent.ACTION_VIEW, android.net.Uri.parse(stringBuffer.toString()));
                intent1.addCategory(Intent.CATEGORY_DEFAULT);
                intent1.setPackage("com.autonavi.minimap");
                startActivity(intent1);

        }else if (isAvilible(SmallDetailActivity.this,"com.google.android.apps.maps")){//網頁版的 
            StringBuffer stringBuffer = new StringBuffer("google.navigation:q=").append(latitudes).append(",").append(longitude).append("&mode=d");
            Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(stringBuffer.toString()));
            i.setPackage("com.google.android.apps.maps");
            startActivity(i);
        } else{//未安裝
            //market為路徑，id為包名
            //顯示手機上所有的market商店
showToast("您尚未安裝地圖軟體");
//            Uri uri = Uri.parse("market://details?id=com.baidu.BaiduMap");
//            intent = new Intent(Intent.ACTION_VIEW, uri);
//            startActivity(intent);
}

    private void openWebGoogleNavi() {
        StringBuffer stringBuffer = new StringBuffer("http://ditu.google.cn/maps?hl=zh&mrt=loc&q=").append(lat).append(",").append(lng);
        Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(stringBuffer.toString()));
        startActivity(i);
    }
