Android gets the phone's screen width, status bar height, and string width-high information method _android

The example in this article describes Android's approach to getting mobile screen width, status bar height, and string width-high information. Share to everyone for your reference. Specifically as follows:

First define the TextView object Commenttext

Get the width of the text:

Textpaint textpaint = new Textpaint (paint.anti_alias_flag);
Textpaint.settextsize (Commenttext.gettextsize ());
Textpaint.setcolor (color.white);
FontMetrics FontMetrics = Textpaint.getfontmetrics ();
float ftop = fontmetrics.top;
float fbottom = fontmetrics.bottom;
float textHeight = (int) (fbottom-ftop);
float textWidth = (int) textpaint.measuretext (Commenttext.gettext ());

Get the status bar height above the phone screen:

Copy Code code as follows:

Displaymetrics dm = new Displaymetrics ();
Getwindowmanager (). Getdefaultdisplay (). Getmetrics (DM);
int width = dm.widthpixels; Screen width
int height = dm.heightpixels; High screen
Rect frame = new Rect ();
GetWindow (). Getdecorview (). Getwindowvisibledisplayframe (frame);
int statusbarheight = Frame.top; Status bar Height
int contenttop = GetWindow (). Findviewbyid (window.id_android_content). GetTop ();
int titlebarheight = Contenttop-statusbarheight; High title bar

Get Phone screen width:

Copy Code code as follows:

WindowManager wm = (WindowManager) this.getsystemservice (Context.window_service);
int width = Wm.getdefaultdisplay (). getwidth ();//Screen width
int height = Wm.getdefaultdisplay (). GetHeight ();//Screen height

Get TextView width

Textpaint paint = Textview.getpaint ();
float len = Paint.measuretext (string);

To get the screen size:

Displaymetrics dm = new Displaymetrics (); 
Getwindowmanager (). Getdefaultdisplay (). Getmetrics (DM); 
Double x = Math.pow (dm.widthpixels/dm.xdpi,2); 
Double y = Math.pow (dm.heightpixels/dm.ydpi,2); 
Double screeninches = math.sqrt (x+y); Screen size (inches)
