Question

我有一个带有小部件的普通应用程序（小部件是图像按钮）。单击窗口小部件时，我想从MainActivity或WidgetProvider活动中的方法调用方法，或者将onClick附加到窗口小部件，当我单击它时会执行某些操作。我已经阅读了文档，但我发现的唯一一件事就是如何使用小部件打开活动。

我的WidgetProvider活动代码：

package ali.simpleflaslight;

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.hardware.Camera;
import android.media.MediaPlayer;
import android.net.Uri;
import android.widget.ImageButton;
import android.widget.RemoteViews;

public class WidgetProvider extends AppWidgetProvider {

  public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    final int N = appWidgetIds.length;

    // Perform this loop procedure for each App Widget that belongs to this provider
    for (int i = 0; i < N; i++) {
      int appWidgetId = appWidgetIds[i];

      // Create an Intent to launch ExampleActivity
      Intent intent = new Intent(context, MainActivity.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.appwidget_layout);
      views.setOnClickPendingIntent(R.id.imageButton, pendingIntent);

      // Tell the AppWidgetManager to perform an update on the current app widget
      appWidgetManager.updateAppWidget(appWidgetId, views);
    }
  }
  public void someMethod() {
    //I want this method called when imagebutton is pressed.
  }
}

使用上面的代码，点击小部件只会显示我的MainActivity。

向AndroidManifest.xml标记中的<receiver><intent-filter>文件添加操作：

＆＃13;

<action android:name="MY_PACKAGE_NAME.WIDGET_BUTTON" />

＆＃13;

宣告：

＆＃13;

public static String WIDGET_BUTTON = "MY_PACKAGE_NAME.WIDGET_BUTTON";

＆＃13;

在onUpdate()方法中添加与操作匹配的待处理意图：

＆＃13;

Intent intent = new Intent(WIDGET_BUTTON);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.MY_BUTTON_ID, pendingIntent);

＆＃13;

最后，在onRecieve（）方法中：

＆＃13;

 if (WIDGET_BUTTON.equals(intent.getAction())) {
   //Your Code

 }

＆＃13;

Android Widget Onclick Button或其他Activity的方法或方法？
