screen-size

Imagine a full Android device screen, I want it split in to two sections: The upper half has text in it, which may be larger than the space available (or not) and so the text will scroll (i.e. TextView inside a ScrollView) The lower half contains a MapView control. Looking specifically at some scenarios: If the text is small, I want the map to take up more space, i.e. more than 50%. So perhaps 20% text, 80% map. If the text is larger, it only takes up a MAXIMUM of 50% of the screen space, and then scrolls. So 50% map, 50% text. At the moment I've assigned weights to the two parts, and that isn

I want to show 3x3 sized gridview. I want to set the height and width based on device size. I am taking reference from this link . MainActivity- public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); GridView gridview = (GridView) findViewById(R.id.gridview); gridview.setAdapter(new ImageAdapter(this)); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } } activity_main- <?xml version="1.0" encoding

I want to resize the screen on Android device. When I run the following commands: adb shell wm density 240 or adb shell wm size 800x480 I get error: /system/bin/sh: wm: not found . Why? How can I resolve that? I should mention that my device is rooted and its model is Asus transformer TF101 I changed it to: adb shell am display-size 800x480 and it worked wm (Window Manager) is not available on Jelly Bean and older devices. for pre jelly bean use adb shell am display-density 240 or adb shell am display-size 800x480 来源： https://stackoverflow.com/questions/30839523/error-on-running-adb-shell-wm

I'm looking for an Algorithm or Pattern to calculate where objects can be placed on multiple resolutions. So far, I have got the X and Y screen size, but im not sure how to turn it into a calculation that would place something such as a drawText() at a location on the screen no matter the screen size. I was thinking perhaps using percentages might be easier to work with. I have a program that draws text to the screen at the top left corner indicating what position the screen has been touched. when i run this on the emulator, with the drawText(info, 10,10, paint); it displays great, but when i

How can I get the screen size programmatically in inches(for example iPhone 4, 3.5 inches). I found a way to do it by detecting the iPhone/iPad model but hard coding is not what I want so I am not looking something like that. This will find the diagonal screen size of a device: float scale = [[UIScreen mainScreen] scale]; float ppi = scale * ((UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) ? 132 : 163); float width = ([[UIScreen mainScreen] bounds].size.width * scale); float height = ([[UIScreen mainScreen] bounds].size.height * scale); float horizontal = width / ppi, vertical = height

I am developping a qt5 application on my raspberry pi on raspbian using cross compilation. When I run it, I get a black screen trying display a Pop-up which is a QFrame. I suppose that it cannot be positioned because I have error messages arriving at the beginning : EGLFS: Unable to query physical screen size, defaulting to 100 dpi. EGLFS: To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters). EGLFS: Unable to query screen depth, defaulting to 32. EGLFS: To override, set QT_QPA_EGLFS_DEPTH. When I disable the QFrame, the application is launched in full
