Android TextView Justify Text

Question

How do you get the text of a TextView to be Justified (with text flush on the left- and right- hand sides)?

I found a possible solution here, but it do

Answer 1

I write my own class to solve this problem, Here it is Just you have to call the static justify function that takes two arguments

1. Text View object
2. Content Width (Total width of your text view)

//MainActivity

package com.fawad.textjustification;
import android.app.Activity;
import android.database.Cursor;
import android.graphics.Point;
import android.graphics.Typeface;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.Display;
import android.view.Gravity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {
    static Point size;
    static float density;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Display display = getWindowManager().getDefaultDisplay();
        size=new Point();
        DisplayMetrics dm=new DisplayMetrics();
        display.getMetrics(dm);
        density=dm.density;
        display.getSize(size);


        TextView tv=(TextView)findViewById(R.id.textView1);
        Typeface typeface=Typeface.createFromAsset(this.getAssets(), "Roboto-Medium.ttf");
        tv.setTypeface(typeface);
        tv.setLineSpacing(0f, 1.2f);
        tv.setTextSize(10*MainActivity.density);

        //some random long text
         String myText=getResources().getString(R.string.my_text);

         tv.setText(myText);
        TextJustification.justify(tv,size.x);


    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

//TextJustificationClass

package com.fawad.textjustification;

import java.util.ArrayList;

import android.graphics.Paint;
import android.text.TextUtils;
import android.widget.TextView;

public class TextJustification {

    public static void justify(TextView textView,float contentWidth) {
        String text=textView.getText().toString();
        Paint paint=textView.getPaint();

        ArrayList lineList=lineBreak(text,paint,contentWidth);

        textView.setText(TextUtils.join(" ", lineList).replaceFirst("\\s", ""));
    }


    private static ArrayList lineBreak(String text,Paint paint,float contentWidth){
        String [] wordArray=text.split("\\s"); 
        ArrayList lineList = new ArrayList();
        String myText="";

        for(String word:wordArray){
            if(paint.measureText(myText+" "+word)<=contentWidth)
                myText=myText+" "+word;
            else{
                int totalSpacesToInsert=(int)((contentWidth-paint.measureText(myText))/paint.measureText(" "));
                lineList.add(justifyLine(myText,totalSpacesToInsert));
                myText=word;
            }
        }
        lineList.add(myText);
        return lineList;
    }

    private static String justifyLine(String text,int totalSpacesToInsert){
        String[] wordArray=text.split("\\s");
        String toAppend=" ";

        while((totalSpacesToInsert)>=(wordArray.length-1)){
            toAppend=toAppend+" ";
            totalSpacesToInsert=totalSpacesToInsert-(wordArray.length-1);
        }
        int i=0;
        String justifiedText="";
        for(String word:wordArray){
            if(i
