nasıl bir aktivite verileri ile liste görünümü yüklemeden önce bir liste görünümü olan ilerleme çubuğu(aşağı) göstermek için

ListView benim ikinci activity.OnItemClick Bir ben bir Java eklentisi olarak adlandırılan ve veri almaya çalışıyorum. Ve ondan sonra da ListView açıklama olan önceki faaliyetleri ** 10 öğe olan üçüncü etkinlik için taşınıyorum.

ListView Bu doldurma önce ilerleme iletişim kutusu görüntülemek istiyorum.

ListView nasıl anlamadım? Herkes bunu nasıl biliyor mu?

activity yüklenirken bir ilerleme çubuğu (aşağı) göstermek için çeşitli yöntemler vardır. Senin durumunda, bir ile bir 16**.

ACTİONBAR

Eğer ActionBar (onCreate() git. ProgressBar diyebilirsin bir kullanıyorsanız

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);  
setProgressBarIndeterminateVisibility(true);

Ve listeyi görüntülemek, gizlemek için yapılır sonra.

setProgressBarIndeterminateVisibility(false);

DÜZENİ (XML)

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@ id/linlaHeaderProgress"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:visibility="gone" >

        <ProgressBar
            android:id="@ id/pbHeaderProgress"
            android:style="@style/Spinner"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >
        </ProgressBar>
    </LinearLayout>

    <ListView
        android:id="@ id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1"
        android:cacheColorHint="@android:color/transparent"
        android:divider="#00000000"
        android:dividerHeight="0dp"
        android:fadingEdge="none"
        android:persistentDrawingCache="scrolling"
        android:smoothScrollbar="false" >
    </ListView>
</LinearLayout>

Ve aktivite (Java) Benim listeler için veri getirmek için bir AsyncTask kullanıyorum. Bu YÜZDEN AsyncTask onPreExecute() bu gibi bir şey kullanabilirsiniz:

// CAST THE LINEARLAYOUT HOLDING THE MAIN PROGRESS (SPINNER)
LinearLayout linlaHeaderProgress = (LinearLayout) findViewById(R.id.linlaHeaderProgress);

@Override
protected void onPreExecute() {    
    // SHOW THE SPINNER WHILE LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.VISIBLE);
}

ve onPostExecute(), ListView adaptör ayarladıktan sonra:

@Override
protected void onPostExecute(Void result) {     
    // SET THE ADAPTER TO THE LISTVIEW
    lv.setAdapter(adapter);

    // CHANGE THE LOADINGMORE STATUS TO PERMIT FETCHING MORE DATA
    loadingMore = false;

    // HIDE THE SPINNER AFTER LOADING FEEDS
    linlaHeaderProgress.setVisibility(View.GONE);
}

EDİT: Bu birkaç ListViews yüklenirken benim app nasıl göründüğünü
