我有一个小部件,带有一个按钮和一个图像按钮。 我希望如果您单击图像按钮,则会打开带有edittext的transparant活动。 例如我们填写01 与单击普通按钮时相比,它将加载显示html文件01.html的webview。 这可能吗?

我的代码是:

 package com.kerk.liedboek.widget;

 import android.app.Notification;
 import android.app.NotificationManager;
 import android.app.PendingIntent;
 import android.appwidget.AppWidgetManager;
 import android.appwidget.AppWidgetProvider;
 import android.content.Context;
 import android.content.Intent;
 import android.util.Log;
 import android.widget.RemoteViews;
 import android.widget.Toast;

  public class main extends AppWidgetProvider {

      public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
      public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";

      @Override 
      public void onUpdate(Context context, AppWidgetManager 
 appWidgetManager, 
        int[] appWidgetIds) { 
            Intent i = new Intent(context, edit.class); 
            PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0); 
            RemoteViews rv = new RemoteViews(context.getPackageName(), 
 R.layout.main); 
            rv.setOnClickPendingIntent(R.id.button_one, pi); 

            Intent i2 = new Intent(context, webview.class); 
            PendingIntent pi2 = PendingIntent.getBroadcast(context,0, i2,0); 
            RemoteViews rv2 = new RemoteViews(context.getPackageName(), 
 R.layout.main); 
            rv2.setOnClickPendingIntent(R.id.button_two, pi2); 

    }
}

但是我的代码是另一个代码,但也是一个按钮小部件:

package com.liedboek.widget;

 import android.app.Activity;
 import android.app.PendingIntent; 
 import android.appwidget.AppWidgetManager;
 import android.appwidget.AppWidgetProvider;
 import android.content.Context;
 import android.content.Intent;
 import android.os.Bundle;
 import android.widget.RemoteViews;

 public class main extends AppWidgetProvider {

public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";

@Override 
public void onUpdate(Context context, AppWidgetManager 
appWidgetManager, 
  int[] appWidgetIds) { 
    // Create an Intent to launch ExampleActivity
    Intent intent = new Intent(context, aantekening.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

    // Get the layout for the App Widget and attach an on-click listener
    // to the button
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main);
    views.setOnClickPendingIntent(R.id.button_one, pendingIntent);

    // Tell the AppWidgetManager to perform an update on the current app widget
    appWidgetManager.updateAppWidget(appWidgetIds, views); 



  } 
 }

答案 0 :(得分:1)

您可能希望使用getBroadcast

,而不是使用getActivity
