I have an application that installs an exchange of funds and shows them in RecyclerView.
My application worked fine before I made a simple theme change. I changed it from @android:style/Theme.AppCompat.Light.NoActionBar"
@android:style/Theme.NoTItleBar.Fullscreen
because I wanted to hide the status bar when my application loads at startup.
manifest
<activity android:name=".Splash"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
Class splash
public class Splash extends Activity {
private final int SPLASH_DISPLAY_LENGHT = 5000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.initial_activity);
new InitialViewLoad().execute();
}
private class InitialViewLoad extends AsyncTask<Void, Void, Long> {
@Override
protected Long doInBackground(Void ... params) {
long before = System.currentTimeMillis();
List<Fund> funds = FundPortfolio.get(getApplicationContext()).getFunds();
new PricesFetcher().fetchItems(funds);
for (Fund fund : funds) {
new FinanceFetcher().fetchItems(fund);
FundPortfolio.get(getApplicationContext()).updateFund(fund);
}
long after = System.currentTimeMillis();
long time = after - before;
return time;
}
@Override
protected void onPostExecute(Long time) {
Intent i = new Intent(Splash.this, MainActivity.class);
synchronized (this) {
try {
if (SPLASH_DISPLAY_LENGHT - time > 0) {
wait(SPLASH_DISPLAY_LENGHT - time);
}
} catch (InterruptedException ioe) {
Log.e("Blah,Blah,Blah", "Blah", ioe);
} finally {
startActivity(i);
finish();
}
}
}
}
}
