安卓与html混合开发之原生与js相互调用
来源：互联网 发布：一元提现微信红包软件 编辑：程序博客网 时间：2024/05/20 04:09
原生和html的优缺点就不多说了，有些特定条件下用html页面可以很方便，也很容易更新和维护，那么这就涉及到html与安卓原生的交互和通信。
接下来我要分享的是html调用原生的弹窗和位置信息，安卓原生调用JS中的方法。
xml很简单：
<?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之后就开始加载html以及几个关键代码：
webView.setWebChromeClient(new WebChromeClient() ); webView.getSettings().setJavaScriptEnabled(true); //开启JavaScript支持 // 添加一个对象, 让JS可以访问该对象的方法, 该对象中可以调用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，它是解决js中alert不弹出的问题和其它内容的渲染问题。
关键的两行代码说一下，首先是js调用原生的方法：webView.addJavascriptInterface(new JSInterface1(),"baobao");JSInterface1内部类中的方法都是提供给js调用的，“baobao”相当于一个“id”，用于标记原生的对象，被html用来调用原生的方法，就相当于引用一样。另一行重要的代码就是webView.loadUrl("javascript: showMsg()");loadUrl方法内的字符串就是调用js中的方法。
JSInterface1：
class JSInterface1 { //JavaScript调用此方法 @JavascriptInterface public void callAndroidMethod(int a, float b, String c, boolean d) { if (d) { String strMessage = "a+b+c=" + a + b + c; T.showThort(mContext, strMessage);// showPopupWindowIntroDestine(); } } @JavascriptInterface public void callLocation() { runOnUiThread(new Runnable() { @Override public void run() { //获取Location /** * 获取地理位置 */ String locaLocation = getLocaLocation(); } }); } @JavascriptInterface public void callAlert(final String info) { runOnUiThread(new Runnable() { @Override public void run() { PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.getAlert(info, 0.3f); } }); } /** * @param info */ @JavascriptInterface public void callConfirm(final String info) { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.seConfirmButtonText("确认", "取消"); popUtils.getConfirm(info, 0.3f, new PopAlertStyleUtils.CallBackLeftRightButton() { @Override public void rightButton(View v) { popUtils.popDismiss(); } @Override public void leftButton(View v) { T.showThort(mContext, "我是左边按钮"); } }); } }); } @JavascriptInterface public void callPrompt(final String info) { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.setLeftRightBtText("继续", "不玩了"); popUtils.getPromptWindow(info, 0.3f, new PopAlertStyleUtils.CallBackPrompt() { @Override public void rightButton(View v, EditText editText) { popUtils.popDismiss(); } @Override public void leftButton(View v, EditText editText) { T.showThort(mContext, "请继续玩吧-----" + editText.getText().toString()); } }); } }); } @JavascriptInterface public void callLoading(final String info) { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.getLoading(info, 0.3f); new Handler() { }.postDelayed(new Runnable() { @Override public void run() { popUtils.popDismiss(); } }, 2000); } }); } @JavascriptInterface public void callToast(final String info) { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.getToast(info, 1.0f); new Handler() { }.postDelayed(new Runnable() { @Override public void run() { popUtils.popDismiss(); } }, 2000); } }); } @JavascriptInterface public void callActionsheet() { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.setTitle("Who wins"); nameList = new ArrayList<String>(); nameList.add("张赛宝"); nameList.add("小黄"); nameList.add("张绍均"); nameList.add("杨峰"); popUtils.getActionsheet(0.3f, new PopAlertStyleUtils.CallBackActionSheet() { @Override public void backListView(ListView listView, Button button) { button.setText("确定"); NameListAdapter adapter = new NameListAdapter(mContext, nameList); listView.setAdapter(adapter); button.setOnClickListener(new ButtonOnclick()); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { webView.loadUrl("javascript: showMsg()"); } }); } }); } }); } @JavascriptInterface public void callChosen() { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.setTitle("Who wins"); final List<String> choseList = new ArrayList<>(); choseList.add("张赛宝"); choseList.add("小黄"); choseList.add("张绍均"); choseList.add("杨峰"); popUtils.getChosen(0.3f, new PopAlertStyleUtils.CallBackChosen() { @Override public void backChosen(ListView listView) { final ChosenAdapter adapter = new ChosenAdapter(mContext, choseList); listView.setAdapter(adapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { adapter.setSelectNum(position); adapter.notifyDataSetChanged(); } }); } }); } }); } @JavascriptInterface public void callModal() { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.setTitle("2.5版本更新"); popUtils.setLeftRightBtText("了解更多", "知道了"); popUtils.getModal("1.功能更新2.功能更新", 0.3f, new PopAlertStyleUtils.CallBackModal() { @Override public void rightButton(View v) { T.showThort(mContext, "我是左边按钮"); } @Override public void leftButton(View v) { T.showThort(mContext, "我是右边按钮"); } @Override public void initImag(ImageView imageView) { Glide.with(mContext).load(R.mipmap.bg_banner).transform(new GlideRoundTransform(mContext, 15)).into(imageView); } }); } }); } @JavascriptInterface public void callTimepicker() { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.getDatePicker(); } }); } @JavascriptInterface public void callDatepicker() { runOnUiThread(new Runnable() { @Override public void run() { final PopAlertStyleUtils popUtils = new PopAlertStyleUtils(mContext, parentsView); popUtils.getTimePicker(); } }); } @JavascriptInterface public void btBack() {//返回 runOnUiThread(new Runnable() { @Override public void run() { finish(); } }); } @JavascriptInterface public void btHelp() { runOnUiThread(new Runnable() { @Override public void run() { Intent intent = new Intent(mContext, HelpDemoActivity.class); startActivity(intent); } }); } @JavascriptInterface public void setTitle(final String title) { runOnUiThread(new Runnable() { @Override public void run() { tvTitle.setText(title); } }); } }Html代码，主要就是通过定义的引用 baobao.XXX()调用原生中的方法，可以传递参数。<!DOCTYPE html><html><head> <meta charset="utf-8"/> <script src="http://api.map.baidu.com/api?v=1.2" type="text/javascript"></script><script> function showMsg(){ alert("hello world!"); }function showHelp(){ alert("我是帮助回调"); }function getTitle(){ var id=document.getElementById("text").value; baobao.setTitle(id);} </script></head><body><div className="page-dialog" ><button class="btn"onClick="baobao.callAndroidMethod(100,100,'ccc',true)">我是弹窗按钮</button></div> <div className="page-dialog" ><button class="btn"onClick="baobao.callLocation()">我是地理位置按钮</button></div><div className="page-dialog" > <button class="btn" onClick="baobao.callAlert('我是提示信息')">alert</button></div><div className="page-dialog" > <button class="btn" onClick="baobao.callConfirm('我是提示信息')">confirm</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callPrompt('我是提示信息')">prompt</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callLoading('使劲加载中...')">loading...</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callToast('提交成功')">toast</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callActionsheet()">actionsheet</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callChosen()">chosen</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callModal()">modal</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callTimepicker()">timepicker</button></div> <div className="page-dialog"> <button class="btn" onClick="baobao.callDatepicker()">datepicker</button></div></div><div className="page-dialog"> <button class="btn" onClick="baobao.btBack()">返回页面</button><button class="btn" onClick="baobao.btHelp()">帮助</button></div><div > <input class = "title" id="text"><input type="button" value="修改标题" id="btnn" onclick ="getTitle()"></div></body><style> .btn{background:#00acff;

各个弹窗的效果如下：
效果大概就是这些，还有一个是调用js中的方法然后弹窗显示我就不展示了。获取地理位置和这个弹窗原理是一样的，具体操作请看我另一篇博文。http://blog.csdn.net/jhl122/article/details/53205345。 博客上还有另一种简便的方式弹窗，有兴趣的请看http://blog.csdn.net/u012124438/article/details/53371102。
