i have problems with my own Dialog. I need a Dialog which switches his text more times during my activity. Because of the activity don't need an UI i thought it is a good idea to use the activity as dialog. I set the Theme as @android:style/Theme.Dialog"
This works fine. The Layout is the following.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Evaluation"
android:id="@+id/textView_couchdbactivity_dialog_text"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
My Problem is I want to make something an change the text of this textview. For Example:
textview_couchdbactivity_dialog_text.setText("creating CouchDB");
textview_couchdbactivity_dialog_text.invalidate();
try {
dataManager = new CouchDataManager("evaluationcouchdb", this);
} catch (IOException e)
{
e.printStackTrace();
} catch (CouchbaseLiteException e)
{
e.printStackTrace();
}
textview_couchdbactivity_dialog_text.setText("resetting CouchDB");
textview_couchdbactivity_dialog_text.invalidate();
dataManager.reset();
But the text don't changes. Only at the end of my Activity the text gets changed. How can I resolve this problem?
At the moment my activity looks exactly so(Without any Dialog):

}
}
What I need is a Dialog or something like this which shows the first log of each method. So the user knows at this moment this is happening. Best it would be without using Threads. I tried to insert some stuff inside a thread, but this needs more time then without using a thread.
