Answer 1

first Create new class JustifyTextView.java its alignment the Textview text in center. Am attached full code below

your pakagename;
 import android.content.Context;
 import android.graphics.Canvas;
 import android.text.Layout;
 import android.text.StaticLayout;
 import android.text.TextPaint;
 import android.util.AttributeSet;
 import android.widget.TextView;


public class JustifyTextView extends TextView {

private int mLineY;
private int mViewWidth;

public JustifyTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
    super.onLayout(changed, left, top, right, bottom);
}

@Override
protected void onDraw(Canvas canvas) {
    TextPaint paint = getPaint();
    paint.setColor(getCurrentTextColor());
    paint.drawableState = getDrawableState();
    mViewWidth = getMeasuredWidth();
    String text = (String) getText();
    mLineY = 0;
    mLineY += getTextSize();
    Layout layout = getLayout();
    for (int i = 0; i < layout.getLineCount(); i++) {
        int lineStart = layout.getLineStart(i);
        int lineEnd = layout.getLineEnd(i);
        String line = text.substring(lineStart, lineEnd);

        float width = StaticLayout.getDesiredWidth(text, lineStart, lineEnd, getPaint());
        if (needScale(line)) {
            drawScaledText(canvas, lineStart, line, width);
        } else {
            canvas.drawText(line, 0, mLineY, paint);
        }

        mLineY += getLineHeight();
    }
}

private void drawScaledText(Canvas canvas, int lineStart, String line, float lineWidth) {
    float x = 0;
    if (isFirstLineOfParagraph(lineStart, line)) {
        String blanks = "  ";
        canvas.drawText(blanks, x, mLineY, getPaint());
        float bw = StaticLayout.getDesiredWidth(blanks, getPaint());
        x += bw;

        line = line.substring(3);
    }

    float d = (mViewWidth - lineWidth) / line.length() - 1;
    for (int i = 0; i < line.length(); i++) {
        String c = String.valueOf(line.charAt(i));
        float cw = StaticLayout.getDesiredWidth(c, getPaint());
        canvas.drawText(c, x, mLineY, getPaint());
        x += cw + d;
    }
}

private boolean isFirstLineOfParagraph(int lineStart, String line) {
    return line.length() > 3 && line.charAt(0) == ' ' && line.charAt(1) == ' ';
}

private boolean needScale(String line) {
    if (line.length() == 0) {
        return false;
    } else {
        return line.charAt(line.length() - 1) != '\n';
    }
}

 }

Then go to your xml code replace your textview by this code
