我有一个小部件,有一个按钮和一个图像按钮。 我希望如果你点击图像按钮,用edittext打开一个透明活动。 例如我们填写01 比单击正常按钮时,它将加载显示html文件01.html的webview。 这可能吗?如何使用主屏幕小部件上的按钮?

的代码,我是:

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); 

    } 
}

但我的代码是另一码,同时也是一个按钮控件:

包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); 



    } 
}

而不是使用getBroadcast,你可能想使用getActivity

我把它放在我的代码中,但是当我点击一个按钮时, 。我不明白吗? – Gaauwe
