I have the following situation. Attached is a snippet of code that appears in the OnCreate of my Activity.
CODE:..........
The issue is that my layout never gets displayed until the OnCreate method has compoleted. Since my 3 functions takes about 10 secs to complete, I have a blank screen being displayed for 10 secs. This layout has a progress bar which meant to show the progress thru each function.
I have a simple problem which makes me feel like a stupid. I really need help on this.
I have a SurfaceView which I created with Java code not XML. I created a MediaPlayer which shows its content on that SurfaceView.
When I use, setContentView(mPreview); // where mPreview is a SurfaceView
The video is played on the screen.
I need to add two buttons on the screen. So I tried something like this:
code:.........
This did not change anything. Still the video is displayed on full screen and no buttons appear. I am a java programmer both SE and ME. Things are done in this way on Java.
Does Android have a different approach?
I am trying to display a bunch of image icons in a grid view, with some basic inductive text on the top. This layout is inside a tab pane. For some reason my application just Fore closes without any stack trace when I do this. Here is my lay out file and the corresponding code that uses it in a tab.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android" android:id="@+id/welcomeLayout" android:orientation="vertical"> <TextView android:id="@+id/txtWelcome" text="@string/app_name" > </TextView> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:id="@+id/welcomeGrid" android:horizontalSpacing="10dp" android:numColumns="auto_fit" android:stretchMode="columnWidth" android:gravity="center" android:columnWidth="120dp" android:verticalSpacing="15dp"/>
</LinearLayout>......
Currently, I have a layout which contains a Button, a TextView and an EditText. When the layout is displayed, the focus will be automatically put on the EditText, which will trigger the keyboard to show up on Android phone. It is not what I want. Is there any way that I can set the focus on TextView or on nothing when a layout is displayed?
View 6 Replies View RelatedI am trying to laod the listview dynamically. There are three textviews inside a listview. The text to be set in the textview is fetched from the server. All this is working fine. I am able to fetch the text and am able to display it inside the listview.
The only problem is the position of the textview. The xml layout file is as under:
CODE:.............
If I look at this xml layout in the eclipse layout tab then it is displayed properly. Problem occurs only when the text is fetched dynamically.
I am trying to implement a simple widget for display on the home screen. The problem I am experiencing is that onUpdate is only being called once when I install the widget. The configuration is below. Note: I will not leave update period at 20 secs as I know that would kill battery (just testing).
Configuration:
`<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="294dp" android:minHeight="72dp"
android:updatePeriodMillis="20000"
android:initialLayout="@layout/my_custom_app_widget">`
</appwidget-provider>`
Manifest Excerpt:
`<receiver android:name="MyCustomWidgetProvider"> <intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>`
I am observing the following behavior when I install the widget:
In my WidgetProvider class on onReceive is called then onEnabled then onReceive, then onUpdate.
After that the widget displays and onUpdate is never called again. I also inspect the settings of the provider when onUpdate is called and everything set in XML above (e.g. update period) is correct.

View 4 Replies View RelatedI am using:
Android 4.0.3
OpenCV 2.4.2
Samsung Galaxy S2
The face-detection example (from the opencv 2.4.2) is working perfectly. But now, I would like to create a custom layout and actually work with just the data extracted from face detection and build a game on it. Not necessarily having the FdView surface taking the entire screen.
I have done these modifications below, but just a black screen is displayed. Nothing appears on the screen.
Changed the BaseLoaderCallback in FdActivity.java
Code:
//EXPERIMENT
setContentView(R.layout.fd);
FdView surface = (FdView) (findViewById(R.id.FdView));[code]....

This is the layout that I am inflating in the Adapter. Everything is displayed, but only the second textview which should be displayed at the bottom is getting displayed at the top. Can someone let me know the problem with this?
I I view this in the layout tab in Eclipse then it displays properly. The problem occurs only when the text is fetched dynamically.
On the HTC full screen agenda widget only the date is displayed and not the day.Is there any way to make it show the day?I find it a little annoying as you have to work out what day the date refers to, e.g. 2/5/2010? Using my fingers to count - it's the errr 26 April today, so,you get my drift.Hopefully there'll be some decent calendar apps come along soon.

View 2 Replies View RelatedMy program doesn't work correctly with Android 1.6 (running on Acer), it works correctly with others devices. Apparently, my xml view is not correctly understood with this device (or Android version). With Android 2.1 all is ok, but with Android 1.6 I've a second scroll bars displayed (one for webview another for the scroll view), my last relative layout covers the webview which is not displayed completely. I know that an issue was existing with Android 1.5.
View 3 Replies View RelatedFor a particular activity - what is the best way to store data that needs to be displayed. The issue is that when the user changes orientation, you need to be able to re-render your activity which means you need to get back at that data that you use to render. I understand the MVC design pattern, but I guess I'm wondering where the M should be stored. Global variables? Static members of your activity? Serialized to private storage?
View 2 Replies View RelatedI have a list view with array adapter to show user some information that retrieved from Internet, As we all know reading data from Internet requires some time to finish, but if I try to read data on getView(), it means user must wait and he/she cannot see anything at that time, the screen is black for long a time because it will cost too much time to finish. This is unacceptable.
So I think maybe I can show user a empty list view first and then display a progress dialog to let user know I'm now just reading data. The background task will read data and send message to UI thread when job is done. But there's one problem: I don't know how to get notified when list view is displayed. I mean, I want to know when & where to show that progress dialog when I first show user an empty list?
I have a service class written which gives notification(Toast dialog) on every life cycle method call back. when i run my application all works well. but when run this service class from my test project the toast message are not displayed.

I want that the toast message should also be displayed on subsequent calls to life cycle methods
I have created a textview with the below code:
CODE:.........
As above, i have set the 5 Lines as maximum for the textview.
But my doubt is: if the string which i am going to display in Textview if it exceeds 5 lines, then it will be fitted upto 5 lines ending with "..." characters.
e.g.
Hello this is the demo of
string which i have
created especially for
the demo of textview
and setting maximum...
As same as above, i want to display in TextView output.

I have some activities and I have to display a fullscreen ad image before displaying the activity... all my activities extends a custom activity and I thought it was a great idea to implement that advertisement there, so I did: code...
This works nice... the ad is displayed for 3 seconds and it closes automatically. The problem is that the activity that should be hide for the ad is being created faster, so the user can see it for a second before the ad is created. How can I avoid that behavior? How to make sure the ad activity starts before the another does?
I have created a simple game for Android; I want to prevent users from sending the game to the background by pressing the home or back buttons accidentally. I planned on using a dialog to confirm the user's action. What I want is similar to what Sirius does with their app, if you need an illustration.
I tried adding this action to an overridden onPause(), but the activity vanishes right after the dialog is displayed, so I don't think I'm going about this the right way. How can I fix this?

I have a class that extends android.app.Dialog, the layout is done in an xml file, and the setup (button listeners, etc) is done on the onCreate method. My problem is that whenever the dialog is displayed, then dismissed, and displayed again, the Editable TextViews are still populated with the information that was displayed previously. What is the common way to clear these text fields?

I am new to this group. I had posted a question yesterday in this group. It didn't appear. I thought I made a mistake; so I posted it today and it didn't appear either. I realized now that this group has something called moderators before it reaches the posting. Am I missing something or did anything wrong? My question was a simple application question and didn't have any bad language in it. Could some please let me know if the question was rejected? If so what is reason so that I can correct it.
