text should fill whole line of the textview

Question

I am just starting android may be this question is already on SO. But I am not getting what to search for.

Like I have TextView in which I have to show some Large text right not i am getting this in UI.

But what I have to create is :-

You can see that the If word is long and not able fit in the end then it should break in two lines. But text alignment in the right should be there.

Do anybody know how can I achieve this ? any help and pointers are appreciated. Thanks :)

Answer 1

justify alignment in TextView is what you are looking for and it's not implemented. However, you can try something like this in your layout file:

android:padding="10dp" android:gravity="center"

If this does not suits you, then you can try using WebView instead of textview. Here is a link of a helpfull alingment in webview

Answer 2

I am able to port it to c# from the following code. This method is without using WebView. As the WebView Implementation is quite slow i can't afford that.

Below is the full class of Justified TextView. This is working great This is from https://github.com/merterhk/JustifiedTextView

 import java.util.ArrayList;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Typeface;
import android.text.TextPaint;
import android.view.View;

public class JustifiedTextView extends View {
        String text;
        ArrayList<Line> linesCollection = new ArrayList<Line>();
        TextPaint textPaint;
        Typeface font;
        int textColor;
        float textSize = 42f, lineHeight = 57f, wordSpacing = 15f, lineSpacing = 15f;
        float onBirim, w, h;
        float leftPadding, rightPadding;

        public JustifiedTextView(Context context, String text) {
                super(context);
                this.text = text;
                init();
        }

        private void init() {
                textPaint = new TextPaint(Paint.ANTI_ALIAS_FLAG);
                textColor = Color.BLACK;
        }

        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
                super.onMeasure(widthMeasureSpec, heightMeasureSpec);

                if (font != null) {
                        font = Typeface.createFromAsset(getContext().getAssets(), "font/Trykker-Regular.ttf");
                        textPaint.setTypeface(font);
                }
                textPaint.setColor(textColor);

                int minw = getPaddingLeft() + getPaddingRight() + getSuggestedMinimumWidth();
                w = resolveSizeAndState(minw, widthMeasureSpec, 1);
                h = MeasureSpec.getSize(widthMeasureSpec);

                                if (lineWidth + ww + (lineBuffer.getWords().size() * wordSpacing) > w) {// is
                                        lineBuffer.addWord(word);
                                        totalWordWidth += textPaint.measureText(word);
                                        lineBuffer.setSpacing((w - totalWordWidth - leftPadding - rightPadding) / (lineBuffer.getWords().size() - 1));
