I set sameting to invisible like this on Android: myImageView.setVisibility(View.INVISIBLE);
And then visible like this: myImageView.setVisibility(View.VISIBLE);
I don't know if myImageView is visible or not now, how can I check it like this:
if (IF myImageView IS VISIBLE) {Do something} else {Do something else}
How can I do that? What do I have to write within the brackets?

What's the best way to check if the view is visible on the window?
I have a CustomView which is part of my SDK and anybody can add CustomView to their layouts. My CustomView is taking some actions when it is visible to the user periodically. So if view becomes invisible to the user then it needs to stop the timer and when it becomes visible again it should restart its course.
But unfortunately there is no certain way of checking if my CustomView becomes visible or invisible to the user. There are few things that I can check and listen to: onVisibilityChange, it is for view's visibility change, and is introduced in new API 8 version so has backward compatibility issue onWindowVisibilityChange, but my CustomView can be part of a ViewFlipper's Views so it can pose issues onDetachedFromWindows, this not as useful onWindowFocusChanged //Again my CustomView can be part of ViewFlipper's views. So if anybody has faced this kind of issues please throw some light.
I want to be able to tell if a view is visible in my listview, which is populated by a custom CursorAdapter. How can I do this?

It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?
I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
App is called Tasker. It should be visible in all Donut+ devices but it's only actually visible in Eclair+ devices. Tested on my G1, reported by other users (devices unknown).
Manifest:
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4" />
A dump from the compiled apk confirms that.
Here's the top of my Ant output:
Buildfile: build.xml [setup] Android SDK Tools Revision 6 [setup] Project Target: Android 1.6 [setup] API level: 4 [setup] Importing rules file: platforms/android-1.6/ant/ ant_rules_r2.xml
Copy protect is set to off.
And the app works fine when installed on a Donut device outside the market.
I noticed that appbrain also reports it as 2.0 and higher: http://www.appbrain.com/app/net.dinglisch.android.taskerm

Yet the calendar has not gone away and is still active in Google Calendars. I need that calendar!

View 2 Replies View RelatedIn the android reference site, it is written in the serCursorVisible section that cursor is visible by default and you can give its value as either "true or "false" to change the its visibility on the GUI screen. But in my case , cursor is remaining invisible irrespective of setting the visibility "true" or "false" using android:cursor Visible = "true" in the layout/main.xml. Should I do something more to make cursor visible on the GUI screen or its a bug in android?

View 2 Replies View RelatedI'm going to create widget which needs to update its content every minute (it shows time-related data).
However, there is no need to update widget if it is currently invisible, which means:
screen is turned off
another app is running
widget is placed on another (invisible) home screen tab
What is the best way to update only visible widget every minute - without waking up device nor doing unnecessary computations? After widget becomes visible, small lag before update is acceptable.

I've checked it myself and for what I can see everything is fine. Today two persons reported the problem, one from UK and the other from Italy. They both have recent Android versions that are supported by my application. It sounds they are not doing any error in the search since they used the QRCode I've published on my website, that I'm able to confirm.
