好久沒有寫Andorid程式碼啦！最近剛好要實現一個這個功能，順便就在部落格裡分享一下。

實現目標

先來一張微信功能截圖看看要做什麼

其實就是有一個目的地，點選目的地的時候彈出可選擇的應用進行導航。

大腦動一下，要實現這個功能應該大體分成兩步：

1. 底部彈出可選的地圖選單進行展示
2. 點選具體選單某一項的時候呼叫對應地圖的api進行導航就ok啦

底部選單這裡用PopupWindow來做。

實現

1、選單顯示
PopupWindow支援傳入view進行彈出展示，所有我們直接寫一個選單佈局，高德、百度、騰訊 再加一個取消。

map_navagation_sheet.xml

<?xml version="1.0" encoding="utf-8"?>
 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical">

    <Button
            android:id="@+id/baidu_btn"
            android:layout_width
 
="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/ulz_white_selector"
            android:text="百度地圖"/>
    <include layout="@layout/common_line_view"/>

    <Button
            android:id="@+id/gaode_btn"
            android:layout_width
 
="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/ulz_white_selector"
            android:text="高德地圖"/>
    <include layout="@layout/common_line_view"/>
    <Button
        android:id="@+id/tencent_btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/ulz_white_selector"
        android:text="騰訊地圖"/>
    <include layout="@layout/common_line_view"/>
    <Button
            android:id="@+id/cancel_btn2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/ulz_white_selector"
            android:text="取消"/>
</LinearLayout>

這裡為了顯示效果，自己寫了個PopupWindow的子類，一般你直接用PopupWindow就可以了。

然後在需要呼叫的地方顯示PopupWindow

mapSheetView = LayoutInflater.from(this).inflate(R.layout.map_navagation_sheet, null);

mBottomSheetPop = new BottomSheetPop(this);
                mBottomSheetPop.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
                mBottomSheetPop.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
                mBottomSheetPop.setContentView(mapSheetView);
                mBottomSheetPop.setBackgroundDrawable(new ColorDrawable(0x00000000));
                mBottomSheetPop.setOutsideTouchable(true);
                mBottomSheetPop.setFocusable(true);
                mBottomSheetPop.showAtLocation(this.getWindow().getDecorView(), Gravity.BOTTOM, 0, 0);

2、點選每個選單呼叫對用地圖的導航api
這個每個地圖的官網都會有介紹，你只需要把目的地名稱，經緯度資訊傳過去就好了，沒什麼多說的，直接貼程式碼。

@Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.navigation_btn:
                mBottomSheetPop = new BottomSheetPop(this);
                mBottomSheetPop.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
                mBottomSheetPop.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
                mBottomSheetPop.setContentView(mapSheetView);
                mBottomSheetPop.setBackgroundDrawable(new ColorDrawable(0x00000000));
                mBottomSheetPop.setOutsideTouchable(true);
                mBottomSheetPop.setFocusable(true);
                mBottomSheetPop.showAtLocation(this.getWindow().getDecorView(), Gravity.BOTTOM, 0, 0);
                break;
            case R.id.cancel_btn2:
                if (mBottomSheetPop != null) {
                    mBottomSheetPop.dismiss();
                }
                break;
            case R.id.baidu_btn:
                if (isAvilible(this, "com.baidu.BaiduMap")) {//傳入指定應用包名
                    try {
                        Intent intent = Intent.getIntent("intent://map/direction?" +
                                "destination=latlng:" + mInfo.getLat() + "," + mInfo.getLng() + "|name:我的目的地" +        //終點
                                "&mode=driving&" +          //導航路線方式
                                "&src=appname#Intent;scheme=bdapp;package=com.baidu.BaiduMap;end");
                        startActivity(intent); //啟動呼叫
                    } catch (URISyntaxException e) {
                        Log.e("intent", e.getMessage());
                    }
                } else {//未安裝
                    //market為路徑，id為包名
                    //顯示手機上所有的market商店
                    Toast.makeText(this, "您尚未安裝百度地圖", Toast.LENGTH_LONG).show();
                    Uri uri = Uri.parse("market://details?id=com.baidu.BaiduMap");
                    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                    if (intent.resolveActivity(getPackageManager()) != null){
                        startActivity(intent);
                    }
                }
                mBottomSheetPop.dismiss();
                break;
            case R.id.gaode_btn:
                if (isAvilible(this, "com.autonavi.minimap")) {
                    Intent intent = new Intent();
                    intent.setAction(Intent.ACTION_VIEW);
                    intent.addCategory(Intent.CATEGORY_DEFAULT);

                    //將功能Scheme以URI的方式傳入data
                    Uri uri = Uri.parse("androidamap://navi?sourceApplication=appname&poiname=fangheng&lat=" + mInfo.getLat() + "&lon=" + mInfo.getLng() + "&dev=1&style=2");
                    intent.setData(uri);

                    //啟動該頁面即可
                    startActivity(intent);
                } else {
                    Toast.makeText(this, "您尚未安裝高德地圖", Toast.LENGTH_LONG).show();
                    Uri uri = Uri.parse("market://details?id=com.autonavi.minimap");
                    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                    if (intent.resolveActivity(getPackageManager()) != null){
                        startActivity(intent);
                    }
                }
                mBottomSheetPop.dismiss();
                break;
            case R.id.tencent_btn:
