小部件自動完成的TextView

Question

我想創建一個小部件，當點擊打開一個對話框，一個autocompletetextview（來自main.class）和mainclass執行功能..這是我的小部件類，請告訴我應該穿什麼在Android清單也。 THX

public class AppWidget extends AppWidgetProvider 
{ 
@Override 
public void onReceive(Context ctxt, Intent intent) 
{ 
    if(intent.getAction()==null) 
    { 
     ctxt.startService(new Intent(ctxt,ToggleService.class)); 
    } 
    else 
    { 
     super.onReceive(ctxt, intent); 
    } 

} 

@Override 
public void onUpdate(Context context,AppWidgetManager appWidgetManager, int [] appWidgetIds) 
{ 
    context.startService(new Intent(context,ToggleService.class)); 
    //RemoteViews buildUpdate(context); 
} 

public static class ToggleService extends IntentService 
    { 
    public ToggleService() { 
     super("AppWidget$ToggleService"); 

     } 



@Override 
protected void onHandleIntent(Intent intent) 
{ 
    ComponentName me = new ComponentName(this,AppWidget.class); 
    AppWidgetManager mgr= AppWidgetManager.getInstance(this); 
    mgr.updateAppWidget(me,buildUpdate(this)); 
} 

private RemoteViews buildUpdate(Context context) 
{ 
    RemoteViews updateViews=new RemoteViews(context.getPackageName(),R.layout.widget); 


    Intent i=new Intent(this, AppWidget.class); 
    PendingIntent pi= PendingIntent.getBroadcast(context,0, i,0); 
    updateViews.setOnClickPendingIntent(R.id.phoneState,pi); 
    return updateViews; 
} 

} }在res

widgetxml //

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent"

     android:clickable="true" 
     android:layout_centerInParent="true" 
     android:src="@drawable/ic_launcher" 
    /> 



</RelativeLayout> 

//和widget_provider.xml/XML

 <?xml version="1.0" encoding="utf-8"?> 
    <appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" 

    android:minWidth="79px" 
    android:minHeight="79px" 
    android:updatePeriodMillis="1800000" 
    android:initialLayout="@layout/widget"> 


<TextView 

android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="Loading..." /> 

//和部分從我的清單

<receiver android:name=".AppWidget" 
     android:label="Caller" 
     android:icon="@drawable/ic_launcher" > 
     <intent-filter > 
      <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> 

     </intent-filter> 
     <meta-data 
      android:name="android.appwidget.provider" 
      android:resource="@xml/widget_provider" 
      /> 

    </receiver> 
    <service android:name=".AppWidget$ToggleService" />

UPADTE您的manifest.xml

<receiver android:name=".AppWidget" 
     android:label="Caller" 
     android:icon="@drawable/ic_launcher" > 
     <intent-filter > 
      <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> 
<action android:name="com.app.example.MyWidget.ACTION_WIDGET_CLICK_RECEIVER"/> 

     </intent-filter> 
     <meta-data 
      android:name="android.appwidget.provider" 
      android:resource="@xml/widget_provider" 
      /> 

    </receiver> 
    <service android:name=".AppWidget$ToggleService" /> 

和更新您的AppWidgetProvider：

public class MyWidget extends AppWidgetProvider { 
     public static String ACTION_WIDGET_CLICK_RECEIVER = "ActionReceiverWidget"; 

     public static int appid[]; 
     public static RemoteViews rview; 
     @Override 
     public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
       int[] appWidgetIds){ 
      updateWidgetState(context, ""); 
     } 
     @Override 
     public void onReceive(Context paramContext, Intent paramIntent) 
      { 
      String str = paramIntent.getAction(); 
      if (paramIntent.getAction().equals(ACTION_WIDGET_CLICK_RECEIVER)) { 
       updateWidgetState(paramContext, str); 
      } 
      else 
      { 
        if ("android.appwidget.action.APPWIDGET_DELETED".equals(str)) 
         { 
         int i = paramIntent.getExtras().getInt("appWidgetId", 0); 
         if (i == 0) 
         { 

         } 
         else 
         { 
          int[] arrayOfInt = new int[1]; 
          arrayOfInt[0] = i; 
          onDeleted(paramContext, arrayOfInt); 
         } 
         } 
       super.onReceive(paramContext, paramIntent); 
      } 
      } 
     static void updateWidgetState(Context paramContext, String paramString) 
      { 
      RemoteViews localRemoteViews = buildUpdate(paramContext, paramString); 
      ComponentName localComponentName = new ComponentName(paramContext, MyWidget.class); 
      AppWidgetManager.getInstance(paramContext).updateAppWidget(localComponentName, localRemoteViews); 
      } 
     private static RemoteViews buildUpdate(Context paramContext, String paramString) 
      { 
      // Toast.makeText(paramContext, "buildUpdate() ::"+paramString, Toast.LENGTH_SHORT).show(); 
      rview = new RemoteViews(paramContext.getPackageName(), R.layout.widget_layout); 
      Intent active = new Intent(paramContext, MyWidget.class); 
      active.setAction(ACTION_WIDGET_RECEIVER); 
      active.putExtra("msg", "Message for Button 1"); 
      PendingIntent configPendingIntent = PendingIntent.getActivity(paramContext, 0, active, 0); 
      rmViews.setOnClickPendingIntent(R.id.buttonus1, configPendingIntent); 
      if(parmString.equals(ACTION_WIDGET_CLICK_RECEIVER)) 
      { 

       //open a dialog with a autocompletetextview 
      //your code for update and what you want on button click 

      } 
      return rview; 
      } 
     @Override 
     public void onEnabled(Context context){ 
      super.onEnabled(context); 
      // Toast.makeText(context, "onEnabled() ", Toast.LENGTH_SHORT).show(); 
     } 
     // Called each time an instance of the App Widget is removed from the host 
     @Override 
     public void onDeleted(Context context, int [] appWidgetId){ 
      super.onDeleted(context, appWidgetId); 
      // Toast.makeText(context, "onDeleted() ", Toast.LENGTH_SHORT).show(); 
     } 
     // Called when last instance of App Widget is deleted from the App Widget host. 
     @Override 
     public void onDisabled(Context context) { 
      super.onDisabled(context); 
      // Toast.makeText(context, "onDisabled() ", Toast.LENGTH_SHORT).show(); 
     } 

    }
