android 桌面时钟widget 带秒针
本帖最后由 zxb6749 于 2012-11-29 14:29:31 编辑 我做了一个、但是不知道为什么、跑了一会儿后、秒针就不动了、、我看了下、我暂且估计是线程的原因、但是实在没有好的办法、希望高手多多请教、谢谢阿、在线等、

我现在的代码：
package com.viroyal.appwidget.analogClock;

import java.util.Date;

import com.viroyal.appwidget.R;

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 AnalogClockWidget extends AppWidgetProvider {

private boolean run = true;
private Context mContext;
private int[] Draw = { R.drawable.clock1_second_hand_0,
R.drawable.clock1_second_hand_1, R.drawable.clock1_second_hand_2,

Thread myThread = new Thread() {

public void run() {
while (run) {
try {

} catch (InterruptedException e) {

showTime(mContext);
}
}
};

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
mContext = context;
showTime(context) ；
myThread.start();

}

@Override
public void onEnabled(Context context) {
// TODO Auto-generated method stub
super.onEnabled(context);
run = true;
}

@Override
public void onDeleted(Context context, int[] appWidgetIds) {
run = false;
super.onDeleted(context, appWidgetIds);
}

@Override

super.onDisabled(context);
run = false;
}

private void showTime(Context context) {
RemoteViews updateViews = new RemoteViews(context.getPackageName(),
R.layout.clock_widget);
Date dates = new Date();
int sec = dates.getSeconds();

updateViews.setImageViewResource(R.id.clock_second, Draw[sec]);

ComponentName thisWidget = new ComponentName(context,
AnalogClockWidget.class);
AppWidgetManager.getInstance(context).updateAppWidget(thisWidget,
updateViews);
}
}
[解决办法]
你启动一个service来更新Appwidget吧，不要用线程
service里

public class UpdateWidgetService extends Service {

AlarmManager alarm;
PendingIntent pintent;

public IBinder onBind(Intent intent) {

return null;
}

public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
RemoteViews views = WeatherWidget.getRemoteViews(this);
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this);
int[] appids = appWidgetManager.getAppWidgetIds(new ComponentName(this,
WeatherWidget.class));
WeatherWidget.updateAppWidget(views, this, appWidgetManager);
appWidgetManager.updateAppWidget(appids, views);
Date date = new Date();
long now = date.getTime();
//间隔
long unit = 60000;
int s = date.getSeconds();
unit = 60000 - s * 1000;
pintent = PendingIntent.getService(this, 0, intent, 0);
alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, now + unit, pintent);

}

public void onDestroy() {
if (alarm != null) {
alarm.cancel(pintent);
}
super.onDestroy();
}
}

public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
getRemoteViews(context);
context.startService(new Intent(context,UpdateWidgetService.class));
}

public void onDisabled(Context context) {
super.onDisabled(context);
context.stopService(new Intent(context,UpdateWidgetService.class));
}
