项目中Android与Js交互
一、项目涉及的类：
DetailCourseMainActivity,HtmlCountMainFragment,HtmlCountFragment,HtmlCountJSInterface,AnswerWebView
二、逐步分析：
1.MainActivity:
1）点击：打开页面
showFragment(HtmlCountMainFragment.class);
2）针对返回键的处理：
onBackPressed()：
一般的：super.onBackPressed();return;
对于Html的Fragment要交给HtmlCountMainFragment处理：（针对统计页面返回的回调，不是初始页面，关闭当前页面）
HtmlCountMainFragment htmlCountMainFragment = (HtmlCountMainFragment) fragmentMap.get(HtmlCountMainFragment.class);
if (htmlCountMainFragment.handleBack()) {//关闭内部页面
return;
}
2.HtmlMainFragment：外部主框架View，主要用来包含container:webView,处理JS回调我们的方法执行任务
1）html_main_fragment.xml:
<title-><Refresh->主要部分container
<FrameLayout
android:id="@+id/html_count_content_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFFFF" />
2）加载书籍数据，BookInfo,设置title,可以传给js调用
3）加入接口：ICallMainFragment,给js调用咱们的方法，做相应处理，以达到效果
ICallMainFragment iCallMainFragment = new ICallMainFragment() {
@Override
public void setContentView(AnswerWebView webView) {//refreshLayout设置刷新的控件，滑到最顶部的时候才刷新
refreshLayout.setContentView(webView);
}
@Override
public void dismissProgressDialog() {//调用去掉进度转圈
HtmlCountMainFragment.this.dismissProgressDialog();
}
@Override
public void openNewPage(String urlStr_) {//打开新页面
stackFragment.push(curHtmlCountFragment);//把新页面的HtmlCountFragment放到stack
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.addToBackStack("fragmentname");
ft.hide(curHtmlCountFragment);
HtmlCountJSInterface jsInterface = curHtmlCountFragment.jsInterface;
if (jsInterface != null) {
jsInterface.callJSMethod("onPause()");
}
//new 新的HtmlCountFragment加载新界面
curHtmlCountFragment = new HtmlCountFragment();
curHtmlCountFragment.setCallMainFragment(iCallMainFragment);
ft.add(R.id.html_count_content_layout, curHtmlCountFragment).commitAllowingStateLoss();
curHtmlCountFragment.loadPage(urlStr_);
}
@Override
public boolean closePage() {//关闭页面
if (stackFragment.size() > 0) {
getActivity().getSupportFragmentManager().popBackStack();
curHtmlCountFragment = stackFragment.pop();//回到上一个fragment
curHtmlCountFragment.onResumeBack();//显示
refreshLayout.setContentView(curHtmlCountFragment.webView);
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.show(curHtmlCountFragment).commitAllowingStateLoss();
return true;
} else {
getActivity().finish();
}
return false;
}
@Override
public HtmlCountFragment getCurHtmlFragment() {//获取当前页面的fragment
return curHtmlCountFragment;
}
@Override
public void updateTitle(final String titleTxt) {//更新title
TaskUtils.postMainTask(new Task() {
@Override
public void run() throws Exception {
title.setText(titleTxt);
}
});
}
@Override
public BookInfo getBookInfo() {//获取书的信息
return bookInfo;
}
@Override
public void setEnable(boolean enable) {//设置是否启用下拉刷新
refreshLayout.setEnable(enable);
}
};
将这个接口传递给下一个，内部的HtmlFragment:
curHtmlCountFragment = new HtmlCountFragment();
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.html_count_content_layout, curHtmlCountFragment).commitAllowingStateLoss();
curHtmlCountFragment.setCallMainFragment(iCallMainFragment);//重点
注：StackFragment用于打开新页面，关闭页面使用
private Stack<HtmlCountFragment> stackFragment = new Stack<>();//要打开新页面
3.HtmlFragment:内部webView的Framgent,用于显示页面，调用js接口
1）html_fragment.xml:FrameLayout是new WebView()的容器
<FrameLayout
android:id="@+id/html_count_web_view"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
2）WebView初始化
webView = new AnswerWebView(Up366Application.getGlobalContext());
webView.setHasAnim(false);
callMainFragment.setContentView(webView);
FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.MATCH_PARENT);
webView.setLayoutParams(params);
webviewLayout.removeAllViews();
webviewLayout.addView(webView);
//webView显示出来
webView.setOnFinishedInterface(new AnswerWebView.IOnFinishedInterface() {
@Override
public void onFinish() {
visible(webView);
iCallFragment.dissmissProgressDialog();
jsInterface.callJSMethod("onEnterPage()");//调用Js的onEnterPage方法
}
});
jsInterface = new HtmlCountJSInterface(webView, iCallFragment);
webView.addJavascriptInterface(jsInterface, "jsCountObj");//用于得到网页端的源码
2）加载数据：
if (!StringUtil.isEmptyOrNull(loadUrl)) {
webView.loadUrl(loadUrl);
}else{
loadHtmlCountPage();
}
public void loadHtmlCountPage() {
webView.setBackgroundColor(0xFFF0F0F0);
invisible(webView);
String fileUrl = "file:///" + FileHelper.getAppRootPath() + "/src/count.html";
webView.loadUrl(fileUrl);
}
3）调用Js内部的方法实现显示、隐藏
@Override
public void onResume() {
if (jsInterface != null && resumeCount++ > 0 && callMainFragment.getCurHtmlFragment() == this) {
jsInterface.callJSMethod("onResume()");
}
}
@Override
public void onPause() {
if (callMainFragment.getCurHtmlFragment() == this) {
jsInterface.callJSMethod("onPause()");
}
}
@Override
public void onDestroy() {
jsInterface.callJSMethod("onPageExchange()");
super.onDestroy();
}
4）过渡接口
public interface ICallFragment {
void dissmissProgressDialog();
void setContentView(AnswerWebView webView);
void openNewPage(String url);
void closePage();
void updateTitle(String title);
BookInfo getBookInfo();
void disableRefresh(boolean b);
}
都调用外部Fragment的：callMainFragment.openNewPage(url);
4.HtmlJSInterface：Js调用android接口
1）初始化：
private final HtmlCountFragment.ICallFragment callFragment;
private AnswerWebView webView;
public HtmlCountJSInterface(AnswerWebView webView, HtmlCountFragment.ICallFragment callFragment) {
this.webView = webView;
this.callFragment = callFragment;
}
2）接口：
*1、js用来传递数据
// 保存页面数据接口
@JavascriptInterface
public int saveData(String data, String dataId) {
// 获取页面数据接口
@JavascriptInterface
public String loadData(String dataId) {
*2、js用来传递数据
/**
* 打开新页面
* <p>
* 2016/10/10
*
* @param url [页面路径，相对路径或者绝对路径（以 http:// 开头）]
* @param mode [0 当前webview加载新页面 1 弹出新页面]
*/
@JavascriptInterface
public String open(String url, final int mode) {
*3、js关闭页面
/**
* 关闭当前 webview
*/
@JavascriptInterface
public String closePage() {
*4、js调用android的网络请求
/**
* 通用网络请求GET方法
*/
@JavascriptInterface
public void requestDataFromServer(final int sessionId, String url) {
*5、js获取用户信息
/**
* 判断用户是否登录
*/
@JavascriptInterface
public boolean isAuthed() {//
return AuthInfo.isAuth();
}
*6、获取客户端的书籍信息
/**
* 获取客户端bookId,courseId
*
* @return getCourseBookInfo
*/
@JavascriptInterface
public String getCourseBookInfo() {
BookInfo bookInfo = callFragment.getBookInfo();
CallFragment.get一般般一直回调到能获取到数据的界面，获取到值给他。
5.AnswerWebView
initWebView
loadNextWebViewUrl：ViewPager中，预防多加载页面空白
onScrollChanged：ViewPager中的滑动出现一半的问题
setOnFinishedInterface：webView加载完成后再显示数据的回调
6.Js：Report.html
