问题描述
我已经倒在每一个例子,我能找到,我已经通过从谷歌官方文档不见了。所有我想要做的是从一个按钮,点击一个小部件创建一个Toast通知。
I have poured over every example that I can find and I have gone through the official documentation from google. All I am trying to do is create a toast notification from a button click on a widget.
我可以得到的小部件(和按钮)出现,但我不能让我的意图火灾。我看到这个节目这样做不同的方法的几个例子,但我不能得到它的工作。我没有感觉到这无奈与编码在很长一段时间,我开始觉得愚蠢。
I can get the widget (and button) to appear but I can't get my intent to fire. I have seen several examples that show doing this different ways but I just can't get it to work. I haven't felt this helpless with coding in a long time and I'm starting to feel dumb.
这是我到目前为止有:
public class simpleclick extends AppWidgetProvider {
/** Called when the activity is first created. */
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
Toast.makeText(context, "doing on update", Toast.LENGTH_SHORT).show();
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
Intent intent = new Intent(context, simpleclick.class);
intent.setAction("ham");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main);
views.setOnClickPendingIntent(R.id.Timm, pendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
//@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, "action is: " + intent.getAction(), Toast.LENGTH_SHORT).show();
super.onReceive(context, intent);
}
}
我的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.tblabs.simpleclick"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:name="simpleclick">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/simpleclick" />
</receiver>
</application>
<uses-sdk android:minSdkVersion="5" />
</manifest>
我会AP preciate一些帮助!
I would appreciate some help!
谢谢,温迪
推荐答案
由于 bigstones 写的,你需要使用广播。样品code:
As bigstones wrote, you need to use broadcast.Sample code:
protected PendingIntent getPendingSelfIntent(Context context, String action) {
Intent intent = new Intent(context, getClass());
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
views.setOnClickPendingIntent(R.id.Timm, getPendingSelfIntent(context,
"ham"));
