我是Android開發新手,並且遇到問題。 我希望你們能幫助我;) 我正在一個Appwidget,一個包含多個圖像的線性佈局 的遠程視圖。 我通過一些教程和示例工作, 我能夠構建第一個應用程序,檢測點擊的圖像視圖以打開特定的已安裝的應用程序,或者更改某些Imageviews的圖像資源。如何多次改變一個appwidget(remoteview)的imageview,並在之間進行短暫的休息?
現在我的問題是,我想單擊按鈕時動畫的圖像。 我做了一個drawableAnimation,但後來我讀了遠程視圖不支持這些。
所以我的想法是與 之間稍微休息一下對於實例手動更改圖片:
變化imageview的
0.1秒等待
變化imageview的
0.1秒等待
更改圖片視圖
0.1秒等待
變化imageview的
所以現在我讀了一些有關睡眠(),處理程序和adapterviewflipper(沒有它我能實現的),我真的不知道該往哪個方向走。
這裏是我的AppWidgetProvider
public class MyWidgetProvider extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_demo);
// Button To Change Imageview
remoteViews.setOnClickPendingIntent(R.id.B1, buildButtonPendingIntent(context));
//Buttons to open some installed apps
remoteViews.setOnClickPendingIntent(R.id.T1, getPendingIntent(context, 1));
remoteViews.setOnClickPendingIntent(R.id.T2, getPendingIntent(context, 2));
pushWidgetUpdate(context, remoteViews);
}
public static PendingIntent buildButtonPendingIntent(Context context) {
Intent intent = new Intent();
intent.setAction("com.appwidgettest.intent.action.UPDATEUI");
return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
public static PendingIntent getPendingIntent(Context context, int btnId) {
// starts a htc radio app as standart and if button 2 is clicked it starts
// chrome browser just did this for testing the packagemanager
PackageManager pm = context.getPackageManager();
String gg = "com.htc.fm";
if (btnId==2){gg = "com.android.chrome";
}
Intent intentt= pm.getLaunchIntentForPackage(gg);
PendingIntent pi = PendingIntent.getActivity(context, 0, intentt, 0);
return pi;
}
public static void pushWidgetUpdate(Context context, RemoteViews remoteViews) {
ComponentName myWidget = new ComponentName(context, MyWidgetProvider.class);
AppWidgetManager manager = AppWidgetManager.getInstance(context);
manager.updateAppWidget(myWidget, remoteViews);
}
}
和工作至今Broadcastreciever的代碼。
public class MyWidgetIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals("com.appwidgettest.intent.action.UPDATEUI")){
updateWidgetPictureAndButtonListener(context);
}
}
private void updateWidgetPictureAndButtonListener(Context context) {
final RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_demo);
// Here i Change The Imageviews!
remoteViews.setImageViewResource(R.id.M3, R.drawable.image1);
//here i need a short time sleep of 0.2 seconds for example
remoteViews.setImageViewResource(R.id.M2, R.drawable.image2);
//here too
remoteViews.setImageViewResource(R.id.M1, R.drawable.image3);
// Here to set the Button Listeners
remoteViews.setOnClickPendingIntent(R.id.B1, MyWidgetProvider.buildButtonPendingIntent(context));
remoteViews.setOnClickPendingIntent(R.id.T2, MyWidgetProvider.getPendingIntent(context,2));
remoteViews.setOnClickPendingIntent(R.id.T1, MyWidgetProvider.getPendingIntent(context,1));
MyWidgetProvider.pushWidgetUpdate(context.getApplicationContext(), remoteViews);
}
}
我爲我的英語不好真的很抱歉^^,我希望你能理解大部分:P
如果你有更好的想法爲標題請告訴我
請幫我看看!
