我强烈建议通过 PhoneGap 使用HTML5。没那么难。
编辑：需要几个步骤：
- 将 cordova 添加为库（在我的例子中是
cordova-2.5.0.jar）
- 创建一个将处理返回的 javascript 调用的类（参见下面的
JSComm.java）
- 使用 webview
DroidGap 创建一个活动（见下文）；请注意，Apache 在较新的版本中将其重命名为 CordovaActivity）
- 创建一个 javascript 文件（如下）
- 创建一个 HTML 页面（如下），其中包含对您的 javascript 文件和 cordova javascript 文件的引用（在我的例子中为
cordova-2.5.0.js）
- 在
/res/xml/config.xml中添加一些xml（见下文）
- 不要忘记将您的活动添加到清单中。
JSComm.java
public class JSComm extends CordovaPlugin {
public boolean execute(final String action, final JSONArray args, CallbackContext callbackContext) {
final CallbackContextWrapper callbackContextWrapper = new CallbackContextWrapper(callbackContext);
if (action.equals("MyString")
return handleIt(args.getJSONObject(0));
else
return false;
}
}
MyCordovaActivity.java
public class FormViewer extends DroidGap {
@SuppressLint("SetJavaScriptEnabled")
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.init();
super.appView.getSettings().setJavaScriptEnabled(true);
super.appView.getSettings().setSupportZoom(true);
super.appView.getSettings().setBuiltInZoomControls(true);
super.appView.getSettings().setDisplayZoomControls(false);
super.appView.getSettings().setUseWideViewPort(true);
super.appView.getSettings().setLoadWithOverviewMode(true);
super.loadUrl("file:///" + myHTMLFilePath);
}
public void nextPage() {
this.sendJavascript("nextPage()"); //example
}
}
JSComm.js
function nextPage() {
var inputted = trytogetinputs(); //some method: get all html input elements
cordova.exec(
null, //what to execute when success? Nothing in this case.
function(args) {
addErrorBorders(args); //What to do if fail? add some error borders in this case.
},
"JSComm", //name of CordovaPlugin class
"MyString", //to identify what method was run
[inputted] //some data you can send along.
);
}
