I'm setting up a gridview of 7 columns. I want it to have 6 rows and fill the screen. So, am trying to find the height of the screen excluding actionbar, statusbar and softkeys. Am planning to set this height divided by 6 as the height of each row. For some reason, the height am getting is not accurate.
DisplayMetrics metrics = context.getResources().getDisplayMetrics();
int height = metrics.heightPixels;
This will give you correct screen dimensions
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

How to reduce spinner size like this, reduce it's width & move it's alignment to right. Please refer below screenshots
What I want is below
What I get...
Set Width of spinner
Display display = getWindowManager().getDefaultDisplay();
DisplayMetrics outMetrics = new DisplayMetrics(); display.getMetrics(outMetrics);
int width = outMetrics.widthPixels / 2;
popupWindow.setWidth(width);
I need to get the exactly size screen but i cant get it.
I tried this two different codes:
DisplayMetrics display = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
height = display.heightPixels;
width = display.widthPixels;
Point size = new Point();
getWindowManager().getDefaultDisplay().getSize(size);
height = size.y;
width = size.x;
In both cases the height its correct (1080) but the width its not correct. It must return 1920 but its returning 1794. Its a Samsung Galaxy S4 (1920x1080).
I have a full screen app, with no actionbar or navigation bar, etc.
Why is happening this and how can ai get 1920. Im using API >= 14.

You can try with getRealSize instead of getSize (getRealSize)
Point size = new Point();
getWindowManager().getDefaultDisplay().getRealSize(size);
height = size.y;
width = size.x;

Can i get resolution of android phone..?
if yes then how..?
it will really helpful for me..
Thank you..
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;
This method was introduced in Android API 13, so if you want to get display metrics for previous APIs use:
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int wwidth = displaymetrics.widthPixels;
If you're not in an Activity, you can get the default Display via WINDOW_SERVICE. Also be sure to set your minSdkVersion to at least 4 in AndroidManifest.xml to enable calls to display.getWidth().
WindowManager wm = (WindowManager) ctx.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
int width = display.getWidth(); // deprecated
int height = display.getHeight(); // deprecated
Edit: PhoneGap
Use the following to figure out the display size in pixels
function getDeviceDimention() {
console.log("Device Dimention using PhoneGap");
console.log("Width = " + window.innerWidth);
console.log("Height = " + window.innerHeight);
}
For Cordova / Phonegap, I've found that using
var width = screen.width
var height = screen.height
is more reliable than using
var width = window.innerHeight
var height = window.innerWidth
in order to obtain the resolution of the current display. The latter is unfortunately inaccurate if your mark-up either overflows or does not take up all of the space available on the screen.
For phonegap you can use this
You can use device-width and device-height
<meta name="viewport" content="width=device-width; user-scalable=no" />
You can even get device height and width using jquery & jquery mobile like this
var width = $(window).width();
var height = $(window).height();
NOTE:- Do this when device is ready.
You can call
Display display = getWindow().getWindowManager().getDefaultDisplay();
Point outSize = new Point();
display.getRealSize(outSize);
outSize.x is the width and outSize.y is the height. Hope it help.
like this
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
look at this answer Android: How to get screen dimensions
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels;
int height = dm.heightPixels;
Good luck!
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
good luck

u can get screen resolution like this
Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int width = display.getWidth();
int height=display.getHeight();
Hi i'm working on an application that will be loading images and i'm looking to scale each image to it's largest possible size for instance if the image is a landscape image (if width is larger than height) i would like to stretch the width to fill the width of the phone and scale height to keep it's aspect ratio. If the height is larger than the width i.e. a portrait image the image should be scaled to fit the height of the phone and width should then adjust to keep the aspect ratio i've had a bit of trouble getting this to work here's what i've done so far though any help would be greatly appreciated.
final ImageView i = new ImageView(mContext);
i.setImageResource(mImageIds[position]);
i.setBackgroundResource(android.R.color.black);
//TODO need to get actual size of drawable not view size which is 0
ViewTreeObserver vto = i.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
public boolean onPreDraw() {
int w = i.getMeasuredWidth();
int h = i.getMeasuredHeight();
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
int height = display.getHeight();
if(w <= h){
//TODO need to think about landscape
h = height - convertDpToPixel(50, context);
w = w*(width);
}else{
h = h*(height);
w = width;
}
//TODO set imageview to w and h
return true;
}
});
for get Display width , height
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int wwidth = displaymetrics.widthPixels;
For Resize Imageview
ImageView img=(ImageView)findViewById(R.id.ImageView01);
Bitmap bmp=BitmapFactory.decodeResource(getResources(), R.drawable.sc01);
Bitmap resizedbitmap=Bitmap.createScaledBitmap(bmp, width, height, true);
img.setImageBitmap(resizedbitmap);
Increase either the height or the width to their maximum, depending on which is already greater.
Now, let's say you're working with a landscape image:
You've already expanded the width to it's maximum size, the display's width
The side you expanded is the width of the image, so assuming the display width = width and the image's width = w:
width / w = r
So r would be the ratio between the display width and the image width. Now you need to use this to increase your height.
Simply multiply the height by the ratio, and set the image's new height to the resulting number.
If you end up with a portait image... well, I think you'll be able to figure it out. It's pretty much the same thing.
After all that, I think it would just be a matter of positioning the image in the center of the screen.
I have a layout with an imageview. This imageview should have a 4/3 ratio. In portrait mode i get the width of the screen then compute the height and set the imageView dimensions.
int[] tailles = new int[2];
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int widthScreen = dm.widthPixels;
tailles[0] = widthScreen;
tailles[1] = (tailles[0]*3)/4;
This part works great.
In landscape mode i need to set the imageView width according to the available height. So i need to get the height of the screen minus the status/notification bar.
I saw the value of 48px for the bar in this question. Is it a standard size ?
What the best solution to get the available height regardless of the used device ?
Display d = ((Activity) mContext).getWindowManager()
.getDefaultDisplay();
int h = d.getHeight();
int w = d.getWidth();
in portrait h > w and in landscape w > h
If you're creating an Activity, than you have to have some sort of layout. Get it's root component, and retrieve it's size (getWidth, getHeight). That'll be the available width and height without counting the status bar.
