Question

学习小部件3天后，我终于了解了setOnClickPendingIntent，RemoteViews ......我已经完成了我的小部件。它已经在很多教程的帮助下完成了。但现在我想测试它是否有效。在我读到的时候，最低更新率是30分钟。另一种方法是使用AlarmManager。但是我找不到AlarmManager的任何例子。等了30分钟后，什么也没发生。我改变了一些事情，仍在等待，它改变了......

有没有办法更快地测试它？

 <?xml version="1.0" encoding="utf-8" ?>
    <appwidget-provider
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:minWidth="65dip"
    android:minHeight="30dip"

    android:updatePeriodMillis="180000"
    android:initialLayout="@layout/main" />

CountWidget

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.widget.RemoteViews;

public class CountWidget extends AppWidgetProvider {
    private static final int[] IMAGES = { R.drawable.die_1, R.drawable.die_2,
            R.drawable.die_3, R.drawable.die_4, R.drawable.die_5,
            R.drawable.die_6 };
    public static String ACTION_WIDGET_RECEIVER = "ActionReceiverWidget";
    public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";

    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager,
            int[] appWidgetIds) {
        ComponentName me = new ComponentName(context, CountWidget.class);

        appWidgetManager
                .updateAppWidget(me, buildUpdate(context, appWidgetIds));

        // обновляем виджет
        // appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);

    }

    private RemoteViews buildUpdate(Context context, int[] appWidgetIds) {

        // Создаем новый RemoteViews
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.main);

        remoteViews.setImageViewResource(R.id.left_die, IMAGES[(int) (Math
                .random() * 6)]);

        // Подготавливаем Intent для Broadcast
        Intent configIntent = new Intent(context,
                CountWhatYouWantActivity.class);
        configIntent.setAction(ACTION_WIDGET_CONFIGURE);

        // создаем наше событие
        PendingIntent configPendingIntent = PendingIntent.getActivity(context,
                0, configIntent, 0);

        // регистрируем наше событие

        remoteViews.setOnClickPendingIntent(R.id.left_die, configPendingIntent);
        return (remoteViews);
    }

这可能会有所帮助：

private static Intent updateIntent = new Intent();
{
    updateIntent.setAction(WidgetProvider.ACTION_WIDGET_UPDATE);
    updateIntent.setData(Uri.withAppendedPath(Uri.parse(WidgetProvider.URI_SCHEME + "://widget/id/"), ""));
}

private void setAlarm(Context context) {
    PendingIntent newPending = PendingIntent.getBroadcast(context, 0, updateIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    Time now = new Time();
    now.setToNow();
    long nowMillis = now.toMillis(false);
    long nextMillis = ((nowMillis / 60000) * 60000) + 60000;

    AlarmManager alarms = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    // set the repeating real time clock minute synchronised alarm
    alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 60 * 1000, newPending);

}

在AppWidgetProvider的onEnabled（）方法中调用setAlarm（）函数。

Answer 2

我在这里写了一个答案Android: How do I force the update of all widgets of a particular kind，它允许您的小部件在被点击时进行更新。这可以让您更好地控制何时执行更新。

Answer 3

您只需修改“widget.xml”文件：

android:updatePeriodMillis="15000"

这将导致它在15秒内触发。该数字以毫秒为单位，即1000ms = 1秒......

如何测试我的小部件的onUpdate方法不等待30分钟
