In development we often need to set our application to full screen, there are two ways, one is set in the code, the other way is in the configuration file to change!
First, set in code:
Copy Code code as follows:
Package com.android.tutor;
Import android.app.Activity;
Import Android.os.Bundle;
Import Android.view.Window;
Import Android.view.WindowManager;
public class Opengl_lesson1 extends activity {
public void OnCreate (Bundle sav
When you develop an Android program, sometimes when the program is running, you can't hibernate the system, or some of the runs will stop, so we need to set up a no hibernation, there are two ways:
One is to add permissions,
One is set in code,
It is recommended that you use the first method so that you will be alerted when you install the program:
The first way:
In the Manifest.xml file, use the User-permission statement.
Name is:Android.permi
This article is an example of the implementation of Android programming WebView Adaptive Full-screen method. Share to everyone for your reference, specific as follows:
First type:
Settings.setusewideviewport (true);
Settings.setloadwithoverviewmode (TRUE);
The second type:
websetting settings = Webview.getsettings ();
Settings.setlayoutalgorithm (Layoutalgorithm.single_column);
//flipper.startflipping ();
Then load a Boolean ontouchevent (Motionevent event)
Set a global variable private Float startx;//the position of the finger when it falls
Get by Event.getaction ()
Case motionevent.action_down://Finger drop
{startx = Event.getx ();} --> gets the first horizontal coordinate case
motionevent.action_up://fingers leave
{by judging the event.getx ()-startx>100 to the right to slide, then animate, and show the front side
Startx-event.getx ()

SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_ fullscreen);//Remove Information BarNote: These two lines of code are to be written before the page is displayed, that is, before Setcontentview (r.layout.xxx)Second: Implement the label in the Androidmanifest.xml configuration file Android:themeAndroid:theme= "@
This article mainly introduces the Android monitor screen on the flip of the implementation method, the need for friends can refer to1, Androidmanifest.xml will activity code as follows: 2, code is as follows: public void onconfigurationchanged (Configuration newconfig) {super.onconfigurationchanged (newconfig); Switch to vertical screen if (newconfig.orientati
Android in the custom control, often need to get the width of the screen, each time to write, you can directly encapsulate him into a tool class, directly to use, nonsense do not say, directly on the code

Qt on Android: how to adapt to different screen sizes
How can I use Android apps developed by Qt to adapt to various screen sizes of Android smartphones?
Speaking of the screen size, there are mobile phone screens from 2.8 to 8.9,
Android is a device that runs on a variety of different screen sizes and densities.The Android system provides a unified development environment across devices and handles most of the work to adjust the screen of each application's user interface to display on it. At the same time, the system provides APIs that allow y

Then find the clos

Terms and concepts related to mobile phone resolution
Screen size: the actual physical size, diagonal measurement of the screen. For convenience, Android divides all the screen sizes into four broad sizes: small, normal, large, and extremely large.
1. Understand several concepts
(1) resolution. Resolution is the cell phone screen pixel points, generally described as the screen "wide x high", Android phone screen Common resolution has 480x800, 720x1280, 1080x1920 and so on. 720x1280 indicates that this screen has 720
Android screen adaptation is a tricky thing to note in Android development:Use linear layout (linearlayout) and relative layout (relativelayout) as much as possible,Do not use absolute layout, use dip and SP as much as possible, do not use PX, provide different layout files and pictures for different resolutions, and set multi-resolution support in Androidmainfes
