Different Android Screens, Different colors, can we program screens to look the same?

Is it possible to have a dynamic color scheme that adjusts to the type of display each device has? Greys between screens can look different and I am wondering if there is an efficient way to create similar looks between the colors of screens.

catch the screen oration and create a color .
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;
float oration = height / width;
Color backgroundColor = new Color();
backgroundColor.red(Math.abs(Integer.valueOf((String.valueOf(oration)))*10));

How to get usable screen height in pixels

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;

Dynamically change editTexts position based on screen Size / DPI

I would like to change the position of one element (editText) in my UI when the user taps it. The positioning should be ~20 dp under the actionBar, no matter screen-size or DPI the device is using.
How do I accomplish this using only (java)code? Please try to give a more exact answer. I have seen other examples similar to this but none that explains an exakt scenario? I was thinking of a start like the code below? Then what?:
DisplayMetrics dm = new DisplayMetrics();
mSearchField = (EditText)v.findViewById (R.id.something);
getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
int [] loc = new int[2];
mSearchField.getLocationOnScreen(loc);
int distance = dm.heightPixels - loc[1];

Get the Display height and width using DisplayMetrics.
DisplayMetrics displayMetrics = new DisplayMetrics();
mContext.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int height = displayMetrics.heightPixels;
int width = displayMetrics.widthPixels;
Log.e("width",width+""+height);

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
행운을 빈다.

u can get screen resolution like this
Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int width = display.getWidth();
int height=display.getHeight();

How to get available height in landscape?

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.
