Spletni Android pogledi

To poglavje prikazuje kako vlagati Cordova omogočen spletni pogled komponente znotraj večje Android aplikacije. Podrobnosti o tem, kako te komponente lahko komunicirajo med seboj, si oglejte Uporaba Plugins.

Če niste seznanjeni z Android, morate najprej seznanite z Android platformo vodnik in so najnovejši Android SDK nameščen, preden poskusite bolj nenavadnih razvoj možnost vdelave v spletni pogled. Začenši z 1,9 Cordova, platformo Android temelji na a CordovaWebView komponento, ki temelji na zapuščino CordovaActivity komponento, ki pred datumi 1.9 sprostitev.

1. Sledite tem navodilom, poskrbite, da imate najnovejšo distribucijo Cordova. Travnato gričevje to s cordova.apache.org ter odpreti patentno zadrgo Android paket.

2. Krmarite do Android paket /framework naslovnik ter prost dostop ant jar . Ustvarja na Cordova .jar datoteko, ki je nastala kot/framework/cordova-x.x.x.jar.

3. Kopiraj v .jar datoteke v projektu Android /libs imenik.

4. Dodajte naslednje aplikacije /res/xml/main.xml datoteko, z v layout_height , layout_width in id spremenjene, da ustrezajo uporabi:

   <org.apache.cordova.CordovaWebView
       android:id="@+id/tutorialView"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />
   

5. Spreminjanje dejavnosti tako, da izvaja z CordovaInterface . To bi morale izvajati vključeni metodah. Želite kopirati jih iz /framework/src/org/apache/cordova/CordovaActivity.java , ali pa jih izvajati na svoje. Naslednji odlomek prikazuje osnovno aplikacijo, ki se opira na vmesniku. Opomba kako sklicevano pogled id ujema z id atributa, navedenega v XML fragment prikazan zgoraj:

   public class CordovaViewTestActivity extends Activity implements CordovaInterface {
       CordovaWebView cwv;
       /* Called when the activity is first created. */
       @Override
       public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.main);
           cwv = (CordovaWebView) findViewById(R.id.tutorialView);
           Config.init(this);
           cwv.loadUrl(Config.getStartUrl());
       }
   

6. Če uporabite kamero uporabo, izvajati naslednje:

   @Override
   public void setActivityResultCallback(CordovaPlugin plugin) {
       this.activityResultCallback = plugin;
   }
   /**
    * Launch an activity for which you would like a result when it finished. When this activity exits,
    * your onActivityResult() method is called.
    *
    * @param command           The command object
    * @param intent            The intent to start
    * @param requestCode       The request code that is passed to callback to identify the activity
    */
   public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {
       this.activityResultCallback = command;
       this.activityResultKeepRunning = this.keepRunning;
   
       // If multitasking turned on, then disable it for activities that return results
       if (command != null) {
           this.keepRunning = false;
       }
   
       // Start activity
       super.startActivityForResult(intent, requestCode);
   }   
   
   @Override
   /**
    * Called when an activity you launched exits, giving you the requestCode you started it with,
    * the resultCode it returned, and any additional data from it.
    *
    * @param requestCode       The request code originally supplied to startActivityForResult(),
    *                          allowing you to identify who this result came from.
    * @param resultCode        The integer result code returned by the child activity through its setResult().
    * @param data              An Intent, which can return result data to the caller (various data can be attached to Intent "extras").
    */
   protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
       super.onActivityResult(requestCode, resultCode, intent);
       CordovaPlugin callback = this.activityResultCallback;
       if (callback != null) {
           callback.onActivityResult(requestCode, resultCode, intent);
       }
   }
   

7. Nenazadnje, ne pozabite dodati zaloga niti, sicer plugins so nobenih niti, ko želite zagnati:

   @Override
   public ExecutorService getThreadPool() {
       return threadPool;
   }
   

8. Kopirajte HTML in JavaScript datotek programa Android projekt /assets/www imenik.

9. Izvod v config.xml pila s /framework/res/xml v projekt /res/xml imenik.
