如何使用主屏幕小部件上的按鈕？

Question

我有一個小部件，帶有一個按鈕和一個圖像按鈕。 我希望如果您單擊圖像按鈕，則會打開一個帶有編輯文本的透明活動。 例如我們填寫 01 ，當你點擊普通按鈕時，它會加載一個 webview ，顯示 html 文件 01.html。 這可能嗎？

我的代碼是：

 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); 

    }
}

我是 android 的新手，現在我是新手。 但我希望你能理解我，你可以幫助我。 高威

但我的代碼是另一個代碼，也是一個按鈕小部件：

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); 



  } 
 }

Answer 1

而不是使用getBroadcast您可能想要使用getActivity 。
