Hi all,
my game is in landscape modeby default, done wid setRequestedOrientation(0). in onCrete() our view is getting instanitiated before setContentView()....but every time i slide for keyboard my view is getting reinstanciated,.....is der ne way to avoid this n continue to previous state of view.....


can ne1 plz give me sample code where there's config or savedinst is used for this.....

The simplest way is to specify the orientation in your manifest :



So sliding the keyboard won't have an effect anymore !


See the documentation here :
http://code.google.com/android/reference/android/R.styleable.html#AndroidManifestActivity_screenOrientation

thanx for repling,....

problem is not wid landscape mode its working fine.........but wenever i slide open the keyboard my activity reinitialises my view n game starts form main screen....... is der any way to stop calling onCreat again n agin wen i slide open/close k/b

When changing orientation, the Activity gets destroyed and recreated again. If you have a game, you could probably implement the orientation change by changing your rendering orientation, instead of having the activity being destroyed.

orientation is in landscape by default......but while opening n closing of k/b activity is being recreated causing completly renewing my view.....is der ne way to stop activity to recreate??

Yeah, so, why won't Emmanuel7's sollution work then?

yeah i've done dat.....but still activity still recreates as i slide open or close the keyboard.......game starts in lanscpe but if accidently user opens k/b den game wl restart....we want to avoid dat......

hey guys i got this....was easy really but der ws some prob wid my eclips dats y i was getting prob......nw after cleaning proj n restarting eclips its running fine........trick is to add android:configChanges="orientation" in mainfest xml so onCreate is not called again n again after changing orien.....it'll call onConfigurationChanged instead of onCreate........


thanx for taking intrest in probbb..................

Good to know you find a solution !

But I'm surprised, I though adding the android:screenOrientation="landscape" in your manifest would prevent the onCreate to be called.
My understanding was that this parameter set how Android decides to trigger a "Orientation has changed" trigger ( whether you deal with it or no ).
Setting it to unspecified ( default value ) let the keyboard sliding decide of the orientation
setting it to sensor let the real orientation decides
And I though setting it to landscape would never launch the trigger !

Are you sure it does not work ? ( i don't have the real device ... )

hey sry for late reply....ya it works fine......in xml u hv 2 add android:configChanges="orientation | keyboardhidden" ....u'll hv to check spelling of "keyboardhidden"....i tried it on actual cell G1.....

adding android:screenOrientation="landscape" in your manifest wont stop onCreate call everytime u slid open or close....

what Emmanual told is rt..

But you can do one more thing for this orentation problem...

When you use "configChanges" in your manifest file. When the system config changes it will trigger the new configuration to Configuration.

If you want two diffrent kind of xml screen fo your application (lanscape and portrait),

You can design it.


by invoking this following method in your Activity,


public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}

You must call the super.onConfigurationChanged(newConfig), then only your activity will react for this..

and you can check the orientation like this and you can do what ever you want for the change,



@Override
public void onConfigurationChanged(Configuration newConfig) {

if (Configuration.ORIENTATION_LANDSCAPE == newConfig.orientation){
// Do your change
}else if (Configuration.ORIENTATION_PORTRAIT== newConfig.orientation){
// Do your change
}
};


It should work.. But not yet tested.....

android:versionName="1.0.0">
<application android:icon="@drawable/icon"
android:label="@string/app_name">
<activity android:name=".oriTest"
android:label="@string/app_name"
