我正在嘗試使用啓動時鐘應用程序製作小部件。Android小工具並單擊監聽器
爲什麼這段代碼在真實設備上不起作用?
我做錯了什麼?
@Override
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
PendingIntent pendingIntent;
if (AppWidgetManager.ACTION_APPWIDGET_UPDATE.equals(action))
{
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.clock_appwidget);
pendingIntent = PendingIntent.getActivity(context, 0,getAlarmPackage(context), 0);
views.setOnClickPendingIntent(R.id.imageView1, pendingIntent);
AppWidgetManager.getInstance(context).updateAppWidget(
intent.getIntArrayExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS),
views);
}
}
public Intent getAlarmPackage(Context context)
{
PackageManager packageManager = context.getPackageManager();
Intent AlarmClockIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);
String clockImpls[][] = {
{ "Standard Alarm", "com.android.alarmclock",
"com.android.alarmclock.AlarmClock" },
{ "HTC Alarm ClockDT", "com.htc.android.worldclock",
"com.htc.android.worldclock.WorldClockTabControl" },
{ "Standard Alarm ClockDT", "com.android.deskclock",
"com.android.deskclock.AlarmClock" },
{ "Froyo Nexus Alarm ClockDT",
"com.google.android.deskclock",
"com.android.deskclock.DeskClock" },
{ "Moto Blur Alarm ClockDT",
"com.motorola.blur.alarmclock",
"com.motorola.blur.alarmclock.AlarmClock" },
{ "Samsung Galaxy S", "com.sec.android.app.clockpackage",
"com.sec.android.app.clockpackage.ClockPackage" } };
boolean foundClockImpl = false;
for (int i = 0; i < clockImpls.length; i++)
{
String packageName = clockImpls[i][1];
String className = clockImpls[i][2];
try
{
ComponentName cn = new ComponentName(packageName, className);
packageManager.getActivityInfo(cn,PackageManager.GET_META_DATA);
AlarmClockIntent.setComponent(cn);
foundClockImpl = true;
} catch (NameNotFoundException nf)
{
Log.v("foundclock", nf.toString());
}
}
if (foundClockImpl)
{
return AlarmClockIntent;
}
else
{
return null;
}
}
我在模擬器上運行應用程序,並單擊小部件 - 這項工作。在android 4.0.3上測試,2.2
你必須放更多的日誌語句,並檢查它被阻止的地方。這個接收器類的意圖過濾器是什麼?或者它是一個AppWidgetProvider類? – San
