Phonegap 3.0 Custom Plugin

问题

I put together a plugin for an app some months ago with phonegap 2.7 and it worked perfectly. The plugin basically opens up the users phonebook and returns to my app the details of the contact the user selects.

I have recently upgraded to Phonegap 3.0 and I am trying to convert my plugin to 3.0; However I can't get the plugin to work now that it's all 3.0....here is what I have

ContactView.java

src\com\huronasolutions\plugins\ContactView.java

package com.huronasolutions.plugins;

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.provider.ContactsContract;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.PluginResult;
import org.apache.cordova.CordovaPlugin;

public class ContactView extends CordovaPlugin {
    private static final int PICK_CONTACT = 1;
    private CallbackContext callback;

    @Override
    public boolean execute(String action, JSONArray args, final CallbackContext callbackContext) throws JSONException {
        if (action.equals("getContact")) {

            this.callback = callbackContext;
            cordova.getActivity().runOnUiThread(new Runnable() {
                        public void run() {
                    startContactActivity();
                    PluginResult mPlugin = new PluginResult(PluginResult.Status.NO_RESULT);
                    mPlugin.setKeepCallback(true);
                    callbackContext.sendPluginResult(mPlugin);
                    }
            });
            return true;
        }
        return false;
    }

    public void startContactActivity() {
        Intent intent = new Intent(Intent.ACTION_PICK);
        intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
        this.cordova.startActivityForResult((CordovaPlugin) this, intent,
                PICK_CONTACT);

    }

                        .query(contactData, null, null, null, null);
                if (c.moveToFirst()) {
                    String ContactID = c.getString(c

                    String hasPhone = c

                        Cursor phoneCursor = this.cordova
                                .getActivity()

                                    null);
                    while (emailCur.moveToNext()) {
                        // This would allow you get several email addresses
                        // if the email addresses were stored in an array
                        email = emailCur

                        contactObject.put("phone", number);
                        contactObject.put("email", email);

                        e.printStackTrace();
                    }

                    callback.success(contactObject);
                }
            }
            break;
        }
    }
}

ContactView.js

\assets\www\js\android\ContactView.js

cordova.define("com.huronasolutions.plugins.ContactView", function (require, exports, module) {
    var exec = require("cordova/exec");

    var contactView = {
        show: function (successCallback, failCallback) {

            function success(args) {
                if (typeof successCallback === 'function')
                    successCallback(args);
            }

            function fail(args) {
                if (typeof failCallback === 'function')
                    failCallback(args);
            }

            return exec(
                function (args) { success(args); },
                function (args) { fail(args); },
                'ContactView',
                'getContact',
                []);
        }
    }
    module.exports = contactView;

});

I have the following in the head of my index.html file

<script type="text/javascript" src="js/android/ContactView.js"></script>

When I call it in my code like this

window.contactView.show(
               function (contact) {
                   success({ "contact": contact, "msg": "success" });
               },
               function (fail) {
                   fail({ "msg": "We were unable to get the contact you selected." });
               }
           );

I get the following error in LogCat

*09-17 22:09:24.285: E/Web Console(1679): Uncaught TypeError: Cannot call method 'show' of undefined at file:///android_asset/www/js/txt2.js:477*

When I call it like this

 contactView.show(
                   function (contact) {
                       success({ "contact": contact, "msg": "success" });
                   },
                   function (fail) {
                       fail({ "msg": "We were unable to get the contact you selected." });
                   }
               );

LogCat says contactView is undefined.

Can someone help, I think I have followed every guide I can find online. Thanks

回答1:

Call your plugin like this:

cordova.require("com.huronasolutions.plugins.ContactView").show(
 function (contact) {
   success({ "contact": contact, "msg": "success" });
 },
 function (fail) {
   fail({ "msg": "We were unable to get the contact you selected." });
 }
);

Also make sure you have defined the plugin in your config.xml:

<feature name="contactView">
      <param name="android-package" value="com.huronasolutions.plugins.ContactView"/
</feature>
