嗨,我有一個AysncTask,我想要在完成加載視圖時展開加載視圖,並將其隱藏起來。有誰知道如何做到這一點?目前它沒有顯示加載視圖。Android在AsyncTask中顯示和隱藏視圖
這是我曾嘗試
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
loadingView = LayoutInflater.from(getBaseContext()).inflate(R.layout.loadingcell,
null);
//Check Preferences which sets UI
checkPreferences();
PostTask posttask;
posttask = new PostTask();
posttask.execute();
}
@Override
protected Boolean doInBackground(Void... params) {
boolean result = false;
loadFixtures();
publishProgress("progress");
loadResultsFeed();
publishProgress("progress");
loadNewsFeed();
publishProgress("progress");
return result;
}
protected void onProgressUpdate(String... progress) {
StringBuilder str = new StringBuilder();
for (int i = 1; i < progress.length; i++) {
str.append(progress[i] + " ");
}
}
@Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
Log.v("BGThread", "begin fillin data");
FillData();
loadingView.setVisibility(View.GONE);
}
}
loadingcell.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white"
android:id="@+id/loadingcell">
<include
layout="@layout/header" />
<ProgressBar
android:id="@+id/progressBar1"
style="?android:attr/progressBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="87dp" />
<TextView
android:id="@+id/textView1"
android:layout_width="115dp"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="@+id/progressBar1"
android:gravity="center"
android:text="Loading..."
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="@color/blue" />
</RelativeLayout>
