android-orientation

the docs on setRetainInstance say : This can only be used with fragments not in the back stack. so I started playing with it. I have one Activity with adds first frag A FragmentManager fm = getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); ft.replace(R.id.content, new PackageFragment()); ft.commit then from this frag I run a method from parent Activity which adds frag B to backstack FragmentManager fm = getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); ft.replace(R.id.content, new OrderFragment()); ft.addToBackStack(null); ft.commit(); then

I have prepared one application.My application will be supports both landscape and portrait. When i change the orientation from portrait to landscape it is working fine,But when i change landscape to portrait it is not working.my code is, public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); System.out.println("orientation---"+getResources().getConfiguration().orientation); if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) { setContentView(R.layout.main); System.out.println("landscape-----"); } else if (newConfig.orientation ==

I am stuck with my issue.Thing is that its a custom Tab Widget.In that have multiple tab like Home - News - Abc - PQR . The Activity should be for both orientation like portrait and landscape . so for that each tab have two xml for portrait which is store at layout-port/file.xml and landscape which store at layout-land/file.xml For manage orientation portrait to landscape i have added android:configChanges="orientation|keyboardHidden" rule tag in each activity. TAB_SAMPLE.java Tab file. TAB_GROUP_ACTIVITY each Tab Group activity File file.java Task file After all this stuff i get issue here :

My education application is having a tab host with 6 to 7 tabs with landscape and portrait modes support. In each and every activity associated with a tab, I am showing some student records in list view, with some check boxes for selection and some rating bars, buttons etc. I am getting these student records from remote server through web service call. For some reasons, my app will show one initial relative layout with some buttons after doing some actions/searches It will show results in list view, upon clicking list item or buttons in list view I am showing some other layout. This applies to

I am invoking a camera using an intent and clicking a picture. Presently I am on emulator and would like to force camera to click the pictures in portrait mode(need to capture a video of app working,so orientation change would look bad) but the camera screen appears landscape and all the further activities which I invoke in onActivityResult(). After clicking the picture the Activity layout comes out in landscape mode like this: while all my previous activity have displayed correctly in portrait orientation. I tried adding android:screenOrientation="portrait" android:configChanges="orientation

Context: In the android-7.1.1_r12 api, the android.hardware.camera2 uses a StickyBottomCaptureLayout as a "BottomBar" to display the action buttons (as switch-camera, shutter and recent picture buttons). Whatever the device orientation, this StickyBottomCaptureLayout is displayed always above/near the system bar (which has back, home and other apps buttons). For example, this is what it looks when the rotation degree is 0 or 180 : And, by orienting the device and get a rotation degree as 90 or 270 , the StickyBottomCaptureLayout is now near the system bar: Usually, this above screenshot should

I read almost all article about onSaveInstanceState and onRestoreInstanceState in Stack overflow but I cant solve my problem. I have a text view and button in my main.java and while you click on button value of a ( a is an int variable) variable will increase and show in the text view, but, when I rotate my phone ( orientation change), text view reset. I override onSaveInstanceState and onRestoreInstanceState but it doesn't work. one more thing, I have special layout-land.xml file for landscape view. here is my code import android.app.Activity; import android.graphics.Typeface; import android

I'm developing an app that basically has an ActionBar. When my app starts, the Activity creates the fragments and attaches them to each tab, so when I switch I get different views. The problems arise when I try to rotate the device. After some struggle, I noticed that Android automatically recreates the previously added fragments like this: SummaryFragment.onCreate(Bundle) line: 79 FragmentManagerImpl.moveToState(Fragment, int, int, int) line: 795 FragmentManagerImpl.moveToState(int, int, int, boolean) line: 1032 FragmentManagerImpl.moveToState(int, boolean) line: 1014 FragmentManagerImpl
