Android TextView set word spacing and line spacing

1. Use if you want to set the line spacing of the TextView (do not look at the 2)

Android:linespacingmultiplier= "1.8"

2. If you want to set the word spacing, you need a custom control

<pre name= "code" class= "java" >import android.content.context;import Android.graphics.*;import Android.text.textutils;import Android.util.attributeset;import Android.widget.textview;import Java.util.regex.matcher;import java.util.regex.pattern;/** * Created by Mrni-mac on 14-11-25.    */public class Mytextview extends TextView {private String content;    private int width;    private paint paint;    private int xpadding;    private int ypadding;    private int textHeight;    private int xpaddingmin;    int count;    Record the two-dimensional array of each word int[][] position;        Public Mytextview (Context context) {super (context);    Init ();        } public Mytextview (context context, AttributeSet Attrs) {Super (context, attrs);    Init ();        } public Mytextview (context context, AttributeSet attrs, int defstyle) {Super (context, attrs, Defstyle);    Init ();        } public void SetText (String str) {width = This.getwidth ();        Getpositions (str);  Redraw controls      This.invalidate ();        } public void Init () {paint = new paint ();        Paint.setcolor (Color.parsecolor ("#888888"));        Paint.settypeface (Typeface.default);        Paint.settextsize (dip2px (This.getcontext (), 14f)); Paint.fontmetrics fm = paint.getfontmetrics ();//Get system default font properties TextHeight = (int) (Math.ceil (fm.descent-fm.top) + 2)        ///Get font height//word spacing xpadding = dip2px (This.getcontext (), 4f);        Line spacing ypadding = dip2px (This.getcontext (), 10f);    Relatively small word spacing (letters and numbers should be compact) Xpaddingmin = dip2px (This.getcontext (), 2f);        } @Override protected void OnDraw (canvas canvas) {super.ondraw (canvas); if (! Textutils.isempty (content)) {for (int i = 0; i < count; i++) {Canvas.drawtext (String.valueo            F (Content.charat (i)), position[i][0],position[i][1], paint);        }}} public void Getpositions (String content) {this.content = content;        Char ch; The x of the input pointcoordinate int x = 0;        Current number of rows int linenum = 1;        Count = Content.length ();        Initializes an array of font positions position=new int[count][2];            for (int i = 0; i < count; i++) {ch =content.charat (i);            String str = string.valueof (CH);            The rect that gets the display of each character according to the brush is the bounding box (gets the character width) of the rect rect = new rect ();            Paint.gettextbounds (str, 0, 1, rect);            int strwidth = Rect.width ();            Do some punctuation if (str.equals ("") | | | str.equals ("(")) {strwidth + = Xpaddingmin * 2;            }//When the width of the forward float textwith = strwidth;            No stooped pre-judgment to see if it will be out of bounds x + = Textwith;            Line break if (x > Width) {linenum++;//true number of rows plus one x = 0;            } else {//return to pre-contract position X-= Textwith;            }//Record the position of each word position[i][0]=x; Position[i][1]=textheight * linenum + ypadding * (linenum-1); Determine if the numbers or letters (numbers and letters should be compact)//Enter the next input position each time the input is ready if (Isnumorletters (str)) {x + = Tex            Twith + xpaddingmin;            } else {x + = Textwith + xpadding;    }}//Set the control's height this.setheight ((textHeight +ypadding) * LineNum) based on the content being drawn;        }//Tool class: Determines whether it is a letter or a numeric public boolean isnumorletters (String str) {string regex= "^[a-za-z0-9_]+$";        Pattern P=pattern.compile (regEx);        Matcher M=p.matcher (str);    return m.matches (); }//Tool class: Method of using DP in code (because pixels are directly represented in code) public static int dip2px (context context, float dip) {Final float SC        Ale = Context.getresources (). Getdisplaymetrics (). density;    return (int) (DIP * scale + 0.5f); }}

The XML uses the following

< current package name. Mytextview                  android:layout_width= "match_parent"                  android:layout_height= "wrap_content" android:id= "@+                  Id/video_dec "                 />

The effect is as follows
