Android Question "Real" Screen Height

[LucaMs]

100%y does not return the right value (full screen without title) because it does not consider the System Bar height.

Can someone create a library based on this example to get the "real screen height" and / or the System Bar height?


Thank you

I realized that this is not essential for "my" problem.

However, knowing the height of the system bar may be useful, who knows.

to know status bar height try attached lib.from here http://stackoverflow.com/questions/1016896/get-screen-dimensions-in-pixels?lq=1
this is compiled code:

package ir.arminkh.screenrealsize;

import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;


@ShortName("ScreenRealSize")
@Version(1.00f)
@Author("ArminKH")
public class ScreenRealSize {
   
    public int getStatusBarHeight(BA ba){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;
    }


   
   
}

I have to try it (but I trust you ).

Just one thing: I would change its name.

MANY THANKS, @ArminKH

yes change it,it does not make sense

100%y does not return the right value (full screen without title) because it does not consider the System Bar height.

100%y returns the activity height.

GetDeviceLayoutValues will return the screen size.

 

[LucaMs]

100%y returns the activity height.

GetDeviceLayoutValues will return the screen size.

No, Erel, GetDeviceLayoutValues does not take in account the System Bar

The difference with 100%y is the Title Bar.

 

[Erel]

GetDeviceLayoutValues does include the system bar (the top bar above the title). It doesn't include the bottom bar with the home key that is available on some of the devices.

 

[LucaMs]

I confused their names: what is the name of the bar on the bottom? Mah, I should search, but I'm too lazy (or tired? or old? )

Thank you

not sure but maybe navigation bar

 

[ArminKH]

try attached lib(has a better name)..from here http://stackoverflow.com/questions/...-and-width-of-navigation-bar-programmatically
as my device has not navigation bar so i cant test it.

package ir.arminkh.screencomponentsize;

import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;


@ShortName("ScreenComponentSize")
@Version(1.00f)
@Author("ArminKH")
public class ScreenComponentSize {
   
    public int getStatusBarHeight(BA ba){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;
    }


    public int getNavigationBarHeight(BA ba){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("navigation_bar_height", "dimen", "android");
        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;       
    }
   
}

It works perfectly, thank you, Armin.

Maybe can you add getTitleBarHeight?
It should be equal to Status Bar, however.

attached is based on your link and i'm not sure about it
also it's using @ActivityObject anotation

    private int StatusBarHeight(BA ba) {
        Rect r = new Rect();
        Window w = ba.activity.getWindow();
        w.getDecorView().getWindowVisibleDisplayFrame(r);
        return r.top;
    }
   
     /**
     * Height of the title bar  
     */
    public int TitleBarHeight(BA ba) {
        int viewTop = ba.activity.getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
        return (viewTop - StatusBarHeight(ba));
    }
  
  
  
    /**

    public int StatusBarHeight(){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;
    }

    /**

    public int NavigationBarHeight(){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("navigation_bar_height", "dimen", "android");
        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;      
    }
  

    /**

        if (resId > 0) {
            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;      
    }  
  
  

    /**
     * Default height of an action bar
     */
    public int ActionBarDefaultHeight(){
        int result = 0;
        int resId = BA.applicationContext.getResources().getIdentifier("action_bar_default_height", "dimen", "android");

            result = BA.applicationContext.getResources().getDimensionPixelSize(resId);
        }
        return result;

maybe we need to check our code by erel

Thank you.
It worked for me, getting the navigation bar height.
