我是Android应用程序的新手,因此有一些问题。 使用下面的代码,我正在尝试对ImageButton采取行动。重要的是要记住,这是一个 Widget ,而不是一个Activity。

我在网上搜索了在Widget中使用ImageButton的例子,发现的信息非常少。但是,这个工作示例似乎在Android的不同版本中存在问题。

现在,代码适用于Android的旧版本(2.1-update1),而不适用于新版手机(2.3.5)或平板电脑(3.2.1)

  • 工作 - (2.1-update1,Samsung 5700)
  • 不工作 - (2.3.5,HTC Desire HD)
  • 不工作 - (3.2.1,ASUS)

似乎API已经发生了一些变化,因为它已停止工作。 (我建议的可能性。虽然不确定。)

2.1-update1的LogCat

日志:

D / AAAAAA(3408):======= onReceive

D / AAAAAA(3408):======= onUpdate

在其他版本中看起来甚至函数onUpdate()和onReceive()都不起作用。

我的代码:(测试代码...... :))

请您查看代码并解释此行为。

public class A_Org_WidgetActivity extends AppWidgetProvider {
    private static final String LOG_TAG = "AAAAAA";

    Button btn;
    TextView txt1;
    ImageButton button; 
    boolean bIcon = true;

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

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        Log.d(LOG_TAG, "  ======= onUpdate");

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.hor_bott_4x3);

        Intent configIntent = new Intent(context, ClickOneActivity.class);
        configIntent.setAction(ACTION_WIDGET_CONFIGURE);

        Intent active = new Intent(context, A_Org_WidgetActivity.class);
        active.setAction(ACTION_WIDGET_RECEIVER);
        active.putExtra("msg", "Message for Button 1");

        PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
        PendingIntent configPendingIntent = PendingIntent.getActivity(context, 0, configIntent, 0);

        remoteViews.setOnClickPendingIntent(R.id.ImageButton06, actionPendingIntent);
        remoteViews.setOnClickPendingIntent(R.id.ImageButton07, configPendingIntent);

        appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);

    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // v1.5 fix that doesn't call onDelete Action
        final String action = intent.getAction();
        String msg = "null";

        Log.d(LOG_TAG, "  ======= onReceive");

        if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
            final int appWidgetId = intent.getExtras().getInt(
                AppWidgetManager.EXTRA_APPWIDGET_ID,
                AppWidgetManager.INVALID_APPWIDGET_ID );

            if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                this.onDeleted(context, new int[] { appWidgetId } );
            }
        } else {
            // check, if our Action was called
            if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
                try {
                    msg = intent.getStringExtra("msg");
                    Log.d(LOG_TAG, "  ======= msg = null");
                } catch (NullPointerException e) {
                    Log.d(LOG_TAG, "  Error msg: " + e);
                }
                Toast.makeText(context, msg, Toast.LENGTH_SHORT).show();

                PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, 0);
                NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
                Notification noty = new Notification(R.drawable.icon, "Button 1 clicked",
                        System.currentTimeMillis());
                noty.setLatestEventInfo(context, "Notice", msg, contentIntent);
                notificationManager.notify(1, noty);
            }
            super.onReceive(context, intent);
        }
    }

}
