How do I get the ScreenSize programmatically in android
Copy and paste this code into your Activity
and when it is executed it will Toast
the device's screen size category.
int screenSize = getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK;
String toastMsg;
switch(screenSize) {
case Configuration.SCREENLAYOUT_SIZE_LARGE:
toastMsg = "Large screen";
break;
case Configuration.SCREENLAYOUT_SIZE_NORMAL:
toastMsg = "Normal screen";
break;
case Configuration.SCREENLAYOUT_SIZE_SMALL:
toastMsg = "Small screen";
break;
default:
toastMsg = "Screen size is neither large, normal or small";
}
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
Get screen width and height in Android
Using this code, you can get the runtime display's width & height:
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels;
In a view you need to do something like this:
((Activity) getContext()).getWindowManager()
.getDefaultDisplay()
.getMetrics(displayMetrics);
In some scenarios, where devices have a navigation bar, you have to check at runtime:
public boolean showNavigationBar(Resources resources)
{
int id = resources.getIdentifier("config_showNavigationBar", "bool", "android");
return id > 0 && resources.getBoolean(id);
}
If the device has a navigation bar, then count its height:
private int getNavigationBarHeight() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int usableHeight = metrics.heightPixels;
getWindowManager().getDefaultDisplay().getRealMetrics(metrics);
int realHeight = metrics.heightPixels;
if (realHeight > usableHeight)
return realHeight - usableHeight;
else
return 0;
}
return 0;
}
So the final height of the device is:
int height = displayMetrics.heightPixels + getNavigationBarHeight();
How to get screen dimensions as pixels in Android
If you want the display dimensions in pixels you can use getSize
:
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;
If you're not in an Activity
you can get the default Display
via WINDOW_SERVICE
:
WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
If you are in a fragment and want to acomplish this just use Activity.WindowManager (in Xamarin.Android) or getActivity().getWindowManager() (in java).
Before getSize
was introduced (in API level 13), you could use the getWidth
and getHeight
methods that are now deprecated:
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
For the use case, you're describing, however, a margin/padding in the layout seems more appropriate.
Another way is: DisplayMetrics
A structure describing general information about a display, such as its size, density, and font scaling. To access the DisplayMetrics members, initialize an object like this:
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
We can use widthPixels
to get information for:
"The absolute width of the display in pixels."
Example:
Log.d("ApplicationTagName", "Display width in px is " + metrics.widthPixels);
API level 30 update
final WindowMetrics metrics = windowManager.getCurrentWindowMetrics();
// Gets all excluding insets
final WindowInsets windowInsets = metrics.getWindowInsets();
Insets insets = windowInsets.getInsetsIgnoringVisibility(WindowInsets.Type.navigationBars()
| WindowInsets.Type.displayCutout());
int insetsWidth = insets.right + insets.left;
int insetsHeight = insets.top + insets.bottom;
// Legacy size that Display#getSize reports
final Rect bounds = metrics.getBounds();
final Size legacySize = new Size(bounds.width() - insetsWidth,
bounds.height() - insetsHeight);
How to get android device screen size?
try this code to get screen size in inch
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width=dm.widthPixels;
int height=dm.heightPixels;
double wi=(double)width/(double)dm.xdpi;
double hi=(double)height/(double)dm.ydpi;
double x = Math.pow(wi,2);
double y = Math.pow(hi,2);
double screenInches = Math.sqrt(x+y);
How to get complete screen size of device programmatically in android?
Try as below
int screenSize = getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK;
switch(screenSize) {
case Configuration.SCREENLAYOUT_SIZE_LARGE:
Toast.makeText(this, "Large screen",Toast.LENGTH_LONG).show();
break;
case Configuration.SCREENLAYOUT_SIZE_NORMAL:
Toast.makeText(this, "Normal screen",Toast.LENGTH_LONG).show();
break;
case Configuration.SCREENLAYOUT_SIZE_SMALL:
Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show();
break;
default:
Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show();
}
