【问题描述】:
我有一个由两个按钮和一个图像组成的小部件。我想让它在用户按下按钮时禁用 30 秒。怎样才能达到这种效果?这是我的布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="@dimen/widget_margin"
android:background="#55000000">
<ImageView
android:id="@+id/imageView"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:src="@drawable/bulb"/>
<Button
android:id="@+id/onButton"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="On"
android:background="@drawable/appwidget_dark_bg_clickable"
/>
<Button
android:id="@+id/offButton"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Off"
android:background="@drawable/appwidget_dark_bg_clickable"/>
</LinearLayout>
这是我当前的控制器:
public class WidgetProvider extends AppWidgetProvider {
public static String ACTION_WIDGET_ON = "Lights turning on";
public static String ACTION_WIDGET_OFF = "Lights turning off";
private String serverUrl = //put your server URL here
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent active = new Intent(context, WidgetProvider.class);
active.setAction(ACTION_WIDGET_ON);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.onButton, actionPendingIntent);
active = new Intent(context, WidgetProvider.class);
active.setAction(ACTION_WIDGET_OFF);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.offButton, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_WIDGET_ON)) {
Log.i("onReceive", ACTION_WIDGET_ON);
new RestPostUtil().execute(serverUrl + "/lightsOn");
} else if (intent.getAction().equals(ACTION_WIDGET_OFF)) {
Log.i("onReceive", ACTION_WIDGET_OFF);
new RestPostUtil().execute(serverUrl + "/lightsOff");
} else {
super.onReceive(context, intent);
}
}
}
