安卓與html混合開發之原生與js相互呼叫
阿新 • • 發佈：2019-02-02
原生和html的優缺點就不多說了，有些特定條件下用html頁面可以很方便，也很容易更新和維護，那麼這就涉及到html與安卓原生的互動和通訊。
接下來我要分享的是html呼叫原生的彈窗和位置資訊，安卓原生呼叫JS中的方法。
xml很簡單：
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:id="@+id/linearlayout" android:layout_height="match_parent"> <include layout="@layout/layout_title"></include> <WebView android:id="@+id/wv_location" android:layout_width="match_parent" android:layout_height="match_parent"></WebView> </LinearLayout>
初始化WebView之後就開始載入html以及幾個關鍵程式碼：
webView.setWebChromeClient(new WebChromeClient() ); webView.getSettings().setJavaScriptEnabled(true); //開啟JavaScript支援 // 新增一個物件, 讓JS可以訪問該物件的方法, 該物件中可以呼叫JS中的方法 webView.addJavascriptInterface(new JSInterface1(), "baobao"); webView.setWebViewClient(new MyWebViewClient()); webView.loadUrl("file:///android_asset/PriseLocation.html");
webView.setWebChromeClient(new WebChromeClient());必不可少，它是解決js中alert不彈出的問題和其它內容的渲染問題。
關鍵的兩行程式碼說一下，首先是js呼叫原生的方法：webView.addJavascriptInterface(new JSInterface1(),"baobao");JSInterface1內部類中的方法都是提供給js呼叫的，“baobao”相當於一個“id”，用於標記原生的物件，被html用來呼叫原生的方法，就相當於引用一樣。另一行重要的程式碼就是webView.loadUrl("javascript: showMsg()");loadUrl方法內的字串就是呼叫js中的方法。
JSInterface1：
class JSInterface1 {
//JavaScript呼叫此方法
@JavascriptInterface
public void callAndroidMethod(int a, float b, String c, boolean d) {
if (d) {
String strMessage = "a+b+c=" + a + b + c;
