Android :: ViewFlipper - Force It To Show First View?
Jul 29, 2010
When I add a ViewFlipper, the UI thread seems to wait for the onCreate() method in the activity to be finished. Then it shows the second view. Why does it happen?
My current code is...
Actually, the doSomeLoading consists of a for loop counting to ten millions and doing nothing. Now it just waits for loop to be done and shows the second view.
I would really appreciate a solution without having to create a separate Thread, because it seems to be pointless, invalidate().

I have a ViewFlipper defined that contains 3 views...
CODE:.........
I also have a custom View defined within my Activity...
CODE:........
Some how, I need these linked together so that the 'third_view' defined in the XML layout file needs to be a CompassView, or have a CompassView added to it.
What I can do is drop the 'third_view' from the layout and then add in the CompassView manually..
CODE:........
But then I lose the ability to define other view controls within the layout file.
Can I add CompassView to 'third_view' declaratively?

I would like to switch to certain views in a ViewFlipper. Currently, I have 6 children inside the ViewFlipper. And I am having some buttons for navigation. It is very much similar to "News and weather" application.

I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item.It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row.I simply want to show an individual icon left from the spinner text for each item in the list.

I have, for the time being, a custom view with a 9-patch image as a border.
That custom view is placed three times in a LinearLayout, so it looks like this:
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.
So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.
So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.

ProgressDialog during location tasks either won't show or force closes - I have tried everything!
I now have it in a Handler with a full 1 second delay (one method another post suggested) but it doesn't show. I simply am stuck. Threads are usually force closing when I use those methods.

A few years back on my Dell Axim Microsoft PocketPC, I was able to tell my browser to not show I am a mobile device when surfing web sites.
Example, when I go to Ebay.com the web browser re-directs me to m.Ebay.com which is the mobile version of the web site.
Im using the standard browser, when I go into Settings > Advanced Settings -- Website Settings- View advanced settings for individual websites is greyed out

I am trying to implement a drop down list when a button is clicked.
So, I have a text view and a button in a navigation bar(nav.xml) and a corresponding list view. This navigation bar is included in another page( products.xml)
when the button is clicked i get the list view right below the button(which is what i want to achieve) but its my moving all the contents on the current page downwards, even the text view which is placed in nav bar moved downwards.
I am totally new to Android, any sample examples or a way how to achieve it?

public View getView(int position,View convertView,ViewGroup parent)
{
System.gc();
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null)
{
//imagecursor.moveToPosition(position);
//int id = imagecursor.getInt(image_column_index);
//i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
i.setImageBitmap(bitmap);
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
i.setLayoutParams(new GridView.LayoutParams(100, 100));
}
else
{
i = (ImageView) convertView;
}
return i;
}

I am making an app where I need to filter the contacts as user types.. I m using autoTextView and I am able to successfully query the contacts db for either tel number or name.. However while displaying I can either display name or tel number only as simple cursor only lets me match one list view with one column.. How do I merge the name and tel number column of the cursor so that both of them can be shown in one list view.

I'm trying to show a ScrollView with a button anchored to bottom of screen. This is coded programmatically (without using XML layout for now). The trouble is when the ScrollView has many items (requiring scrolling), it prevents the button at the bottom from showing. The bottom button is sort of pushed off the screen. Look at the code below. I have a TODO which mentions a workaround to specify the exact pixel height of the ScrollView, but this is not a good solution. If you change the for loop to add only 2 buttons, then the bottom button will show. So how do I make the ScrollView show a scrolling list, with the bottom button in view, and without specifying an exact size of the ScrollView? I've seen some discussions here:
http://groups.google.com/group/android-developers/browse_thread/threa http: //groups. google.com /group/ android-developers/browse_thread/threa But I don't know how to apply these to my situation.package com.test.ScrollViewTest; import android.app.Activity; import android.os.Bundle; import android. view. Gravity ; import android.view. ViewGroup. MarginLayoutParams; import android.widget.Button; import android. widget.ImageView; import android .widget.LinearLayout; import android.widget.RelativeLayout; import android.widget.ScrollView; import android.widget.TextView; public class MyScrollViewTest extends Activity @Override public void onCreate(Bundle savedInstanceState) super. onCreate (savedInstanceState); LinearLayout ll = new LinearLayout(this); // the main layout of the screen ll.setOrientation (LinearLayout.VERTICAL); TextView tv1 = new TextView(this); tv1.setText("First line of text"); TextView tv2 = new TextView(this); tv2.setText("Second line of text"); ll.addView(tv1); ll.addView(tv2); ScrollView sv = new ScrollView(this);// You can only add one child (usually a layout) to a scrollview, // otherwise you get exception: "ScrollView can host only one direct child" LinearLayout ll2 = new LinearLayout(this); ll2.setOrientation(LinearLayout.VERTICAL); * TODO: PROBLEM HERE: You cannot use WRAP_CONTENT for height, because * the layout below the scrollView will not show (it's sort of pushed * off the screen - even if a margin is specified). * An alternate value of 300 works OK (remove the bottom margin too).* But this is only suitable for screen size 320x480 in portrait mode.LinearLayout.LayoutParams params Linear = new LinearLayout.LayoutParams( LinearLayout. Layout Params.FILL_PARENT, Linear Layout.LayoutParams.WRAP_CONTENT /*300*/); Add 50 pixel margin to bottom of scrollview (this margin doesn't scroll) paramsLinear.bottomMargin = 50;sv.addView(ll2); // Add some stuff to scrollView to test its depth // (it should leave a margin at bottom of screen) for (int i = 1; i < 10; i++) { TextView textView = new TextView(this) ;textView.setText ("Text View " + i); linearLayout.LayoutParams p = new LinearLayout .LayoutParams (Linear Layout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll2.addView (textView, p); button buttonView = new Button(this); buttonView. setText ("Button " + i);ll2.addView(buttonView, p); ll.addView(sv, paramsLinear); RelativeLayout rl = new RelativeLayout(this); RelativeLayout.LayoutParams paramsRelative = new lative Layout. LayoutParams( RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout .Layout Params .WRAP_CONTENT); // Make the button anchored to the bottom of the screen.// But this doesn't work when the ScrollView has a scrolling list of items. Why? params Relative .addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); rl.setLayout Params (params Relative) ;

How do I ensure that I get the 'resize' behavior when the IME is shown/hidden?
I've included the following in my manifest:
android:windowSoftInputMode="adjustResize"
What else am I supposed to add? I've read that the container that the View is placed in should 'support resize' but what layouts support this?

I just put an address on a contact, saved it, and when i went to view address it give me people app FC! What the hell?
Does it just show you the address or does it try to bring up maps or something like it to actually SHOW you the address? If so, that's why, because i removed all that garbage. Running Fresh 2.1.2.

I'm not sure if this question has been addressed or asked yet, and I couldn't find anything using the search feature, so I'll ask anyways.
Sometimes I get email notifications (using HTC Mail) and I open Mail and go to the new message, but all that shows up is a timestamp of "Wed, Dec 31, 1969 7:00 PM" with no subject, body, or even sender. It's like the email didn't download or I can't view it for some other reason.
