I have a really strange behaviour on my nexus 4 (running android 4.4).
Although I set these Flags in my MainActivity
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
activity.getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
activity.getActionBar().hide();
My Views (e.g. DialogFragments) do get cut by the invisible NotifictaionBar, see the attached Screenshot at the top.
Does anybody have a hint for me what to do, which flags I have to set?
Thanks in advance.
So I figured it out: In this post there is the answer: https://stackoverflow.com/a/20281449/855950
I had to set this flags in my MainActivity
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
getActionBar().hide(); //Be carefull of target API
in the OnCreate of my DialogFragment this line (to hide the Title)
setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo_Light_Dialog);
and in the onCreateView of my Dialog this line:
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
getDialog().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
Works for me :)

I have a Timer in a fragment and I want the timer to pause when the app is minimize(user clicks home or recent apps).
What should I do?
It seems that the fragment doesnt have onPause! The parent activity has it, which is useless because there I don't have access to the timer.
I also tried to make home button and set on click listener for it but I got null pointer exception error and when I used the code below
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==android.R.id.home)
{
Log.d("IT home","clicked");
}
return super.onOptionsItemSelected(item);
}
but it doesn't work. I didn't see anything it the Log cat.
according to the documentation , fragments have an onPause method. you can use it normally like you would do in an activity.
read more about it in the documentation.
I hope this helps you.
I am new to the forum and to programming so hopefully I give you enough details and precise information needed to understand my question.
I am working with vaadin 7 in java EE web aplication and I have a layout problem/phanomena that I cannot explain and I could not find a solution on the net. Basically, when I start the server and test my application on localhost everything looks right. When I open a dialogue window and close it again, the layout of the site looks displaced. I could not find a pattern as to which click causes this effect. Sometimes it happens also when I only change a view. This is how it should look like and this is how it does look like after working in the application.
I looked through the devloper tool in the browser and noticed that in the working html, the attributes "top" and "left" are set for the gridlayout-slot. In the displaced layout these attributes are not set. Furthermore, it seems that the problem occurs more often in chrome. It does also happen in firefox but less often.
I use VerticalLayout, GridLayout and FormLayout.
Did you have similar experience? I am wondering how and when the html files are generated from the vaadin code to find out why they change and how I can fix it.
I am not sure which code exactly is causing the problem, so I am not sure what to post. If you have an idea where to look, I can add more code. Here is how the Dialog is set up:
public class Dialog extends Window implements ClickListener
public Dialog(CustomController controller, String title)
{
super(title);
setModal(true);
setStyleName("dialogWindow");
this.controller = controller;
setWidth("65.0%");
setHeight("90.0%");
// top level component properties
panLayout = new GridLayout();
panLayout.setWidth("100%");
panLayout.setHeight("100%");
buildPanToolbar();
panLayout.addComponent(panToolbar);
buildPanTop();
panLayout.addComponent(panTop);
buildPanTabs();
panLayout.addComponent(tabsheet);
panLayout.setComponentAlignment(tabsheet, Alignment.MIDDLE_CENTER);
panLayout.setRowExpandRatio(2, 1.0f);
tfThema.focus();
setContent(panLayout);
}
The buildSomething() functions are all a combination of GridLayout, FormLayout, HorizontalLayout and VerticalLayout. Below is the buildPanToolbar() function as an example
private void buildPanToolbar()
{
panToolbar = new HorizontalLayout();
panToolbar.setImmediate(false);
panToolbar.setWidth("100%");
panToolbar.setHeight("25px");
panToolbar.setMargin(false);
panToolbar.setSpacing(true);
panToolbar.setStyleName("toolbar");
HorizontalLayout panHelpToolbar = new HorizontalLayout();
panHelpToolbar.setImmediate(false);
panHelpToolbar.setWidth("-1px");
panHelpToolbar.setHeight("25px");
panHelpToolbar.setMargin(false);
panHelpToolbar.setSpacing(true);
panHelpToolbar.setStyleName("toolbarButtons");
panToolbar.addComponent(panHelpToolbar);
pbButton1 = new Button();
pbButton1.setCaption("Button1Text");
pbButton1.setStyleName(BaseTheme.BUTTON_LINK);
pbButton1.setImmediate(true);
pbButton1.setWidth("100px");
pbButton1.setHeight("-1px");
pbButton1.setIcon(new ThemeResource("../images/pic1.gif"));
pbButton1.addClickListener(controller);
panHelpToolbar.addComponent(pbButton1);
panHelpToolbar.setComponentAlignment(pbButton1, Alignment.MIDDLE_LEFT);
pbButton2= new Button();
pbButton2.setCaption("Button2 Text");
pbButton2.setImmediate(true);
pbButton2.setWidth("100%");
pbButton2.setHeight("-1px");
pbButton2.setStyleName(BaseTheme.BUTTON_LINK);
pbButton2.setIcon(new ThemeResource("../images/pic.gif"));
pbButton2.addClickListener(this);
panHelpToolbar.addComponent(pbButton2);
panHelpToolbar.setComponentAlignment(pbButton2, Alignment.MIDDLE_LEFT);
}
after almost 2 week trying to solve this strange problem, I give up!
Basically a get the java.lang.VerifyError every time I try to run my app
only in devices with Android 2.x.x. From 3.x.x all are going well.
In the project I'm using this two external library:
Action Bar Sherlock - http://actionbarsherlock.com/ - updated at the v4.4.0
Sliding Menu - https://github.com/jfeinstein10/SlidingMenu
This is what the LogCat return every time:
FATAL EXCEPTION: main
java.lang.VerifyError: me.xxx.menu.MenuListFragment
at me.xxx.menu.BaseSlidingMenuActivity.onCreate(BaseSlidingMenuActivity.java:46)
at me.xxx.menu.SlidingMenuCustomAnimation.onCreate(SlidingMenuCustomAnimation.java:28)

and this is how the BaseSlidingMenuActivity.java looks like around the line 46:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle(mTitleRes);
// set the Behind View
setBehindContentView(R.layout.frame_content);
if (savedInstanceState == null) {
FragmentTransaction t = this.getSupportFragmentManager().beginTransaction();
mFrag = new MenuListFragment(); <--- ERROR HERE!
t.replace(R.id.frame_content, mFrag);
t.commit();
} else {
mFrag =(SherlockListFragment)this.getSupportFragmentManager()
.findFragmentById(R.id.frame_content);
}
...
...
}
Where MenuListFragment() is a SlidingFragmentActivity that extend a SherlockFragmentActivity
and implements SlidingActivityBase.
Of course I googled the problem, and seems that a lot of people are getting this
issue with the last version of the Android SDK tool, i.e. v22.x.x , in fact a have
the v22.6.3.
Some people resolved the VerifyError just putting the Check on the "Private Libraries"
box, inside "BuildPath->Configure BuildPath->Order and Export" menù, as explained
in other conversation about the VerifyError, but for me doesn't work, even because the "Private Libraries" was already checked. So the libraries/imports situation seems to be ok!
Hoping that someone already fund a solution for that! I'm getting crazy! :D
Thank you!
I finally found the solution!
Recap! Basically the are two main reason in which you can get this error:
(In my case) I was getting the VerifyError all the time that I tried to run my app on devices with API Level under 10 , because I was trying to catch an SQLiteDatabaseLockedException that are supported from the Android API Level 11. So to solve it check that every Exception or possible method (i.e. String.isEmpty() is supported from API Level 9) is supported form your minimum API Level.
While I was searching for a solution I found a lot of people that got the VerifyError because there was some problem with Libraries Imports, as explained in this post: http://commonsware.com/blog/2013/05/23/do-not-manually-modify-eclipse-build-path-except-now-r22.html
Hope that will help someone beyond me! :D
Bye Bye! Caterpillar.
I've looked for it in many web sites. I wanna make my activity full screen in Android 4.0 (Whole screen with even virtual buttons and bar). There are many solutions even in Stack Overflow. Many of them are ticked as it works. However when I try these solutions, they don't work! I couldn't find where I am making the mistake. I'm giving an example code that was given as answer for my problem (it's worked as they said):
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class ActivityName extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
This isn't enough:
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
In order to accomplish what you want to accomplish, add this:
this.getWindow().getDecorView()
.setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
I know this is a rather old question (with a bunch of duplicates), but this is found via Google so I figured I'd still post this solution.
I have 2 fxml files mainFxml.fxml and second.fxml. Main fxml has a button with fx:id="change". I want change scene when change button is clicked.

Node node=(Node) event.getSource();
Stage stage=(Stage) node.getScene().getWindow();
Parent root = FXMLLoader.load(getClass().getResource("second.fxml"));/* Exception */
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}

It's on the classpath so it should be the resource should be precedded with a forward slash i.e.
/second.fxml
That is assuming it is not in a package. Make sure your build system is also copying it to the output directory along with your class files.
"Ah, then you need /demo/second.fxml as the resource path. Saying that, I am confused why the error message says sucess.fxml and not second.fxml. If the above suggestion doesn't work can you post the fxml? – Andy Till"
This comment from Andy Till is the answer to the question.
Thanks Andy. You solved my problem :)
Thumbs up !!!
Include the package name.
For ex:
/package_name/fxml_file_name.fxml
Most probably your file second.fxml is not located in the same folder with mainFxml.fxml's controler java file.
import java.io.IOException;
I got it to work by either surrounding the load(getClass... with a try/catch block, or by just importing java.io.IOException.
Enjoy :)
