donner de l'espace entre le texte et souligner avec CustomView android

Question

Je veux un soulignement ci-dessous EXCLURE comme ci-dessous, mais quand je crée ce sera l'aide de CustomView, souligné apparaît juste en dessous d'opter mais je veux un peu d'espace entre le texte et ligne comme image

J'ai créé une vue Personnalisée, dans laquelle un mot sera recherché dans une chaîne si elle est trouvée, puis le texte correspondant sera souligné mais la seule chose que je veux est de donner un espace entre le soulignement et le texte ,

Ma classe est la suivante,

import android.content.Context; 
import android.content.res.TypedArray; 
import android.graphics.Canvas; 
import android.graphics.Paint; 
import android.graphics.Rect; 
import android.support.v7.widget.AppCompatTextView; 
import android.text.Layout; 
import android.util.AttributeSet; 
import android.view.Display; 
import android.view.WindowManager; 
import android.widget.TextView; 


public class UnderLine extends AppCompatTextView { 

private Rect mRect; 
private Paint mPaint; 
private int mColor; 
private float density; 
private float mStrokeWidth; 
private String stringSeach; 

public UnderLine(Context context) { 
    this(context, null, 0); 
} 

public UnderLine(Context context, AttributeSet attrs) { 
    this(context, attrs, 0); 
} 

public UnderLine(Context context, AttributeSet attrs, int defStyleAttr) { 
    super(context, attrs, defStyleAttr); 
    init(context, attrs, defStyleAttr); 
} 

private void init(Context context, AttributeSet attributeSet, int defStyle) { 

    density = context.getResources().getDisplayMetrics().density; 

    TypedArray typedArray = context.obtainStyledAttributes(attributeSet, R.styleable.UnderLine, defStyle, 0); 
    mColor = typedArray.getColor(R.styleable.UnderLine_underlineColorr, 0xFFFF0000); 
    stringSeach = typedArray.getString(R.styleable.UnderLine_underlineTextt); 
    mStrokeWidth = typedArray.getDimension(R.styleable.UnderLine_underlineWidthh, density * 2); 
    typedArray.recycle(); 

    mRect = new Rect(); 
    mPaint = new Paint(); 
    mPaint.setStyle(Paint.Style.STROKE); 
    mPaint.setColor(mColor); //line mColor 
    mPaint.setStrokeWidth(mStrokeWidth); 
} 

public int getUnderLineColor() { 
    return mColor; 
} 

public void setUnderLineColor(int mColor) { 
    this.mColor = mColor; 
    invalidate(); 
} 

public float getUnderlineWidth() { 
    return mStrokeWidth; 
} 

public void setUnderlineWidth(float mStrokeWidth) { 
    this.mStrokeWidth = mStrokeWidth; 
    invalidate(); 
} 

@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
    super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    setMeasuredDimension(getMeasuredWidth(), getMeasuredHeight()+110); 
} 

@Override 
protected void onDraw(Canvas canvas) { 
    TextView parentTextView = this; 
    Rect parentTextViewRect = new Rect(); 

    String targetWord = stringSeach.toLowerCase(); 
    int startOffsetOfClickedText = this.getText().toString().toLowerCase().indexOf(targetWord); 
    int endOffsetOfClickedText = startOffsetOfClickedText + targetWord.length(); 

    // Initialize values for the computing of clickedText position 
    Layout textViewLayout = parentTextView.getLayout(); 

    double startXCoordinatesOfClickedText = textViewLayout.getPrimaryHorizontal((int)startOffsetOfClickedText); 
    double endXCoordinatesOfClickedText = textViewLayout.getPrimaryHorizontal((int)endOffsetOfClickedText); 

    // Get the rectangle of the clicked text 
    int currentLineStartOffset = textViewLayout.getLineForOffset((int)startOffsetOfClickedText); 
    int currentLineEndOffset = textViewLayout.getLineForOffset((int)endOffsetOfClickedText); 
    boolean keywordIsInMultiLine = currentLineStartOffset != currentLineEndOffset; 
    textViewLayout.getLineBounds(currentLineStartOffset, parentTextViewRect); 

    // Update the rectangle position to his real position on screen 
    int[] parentTextViewLocation = {0,0}; 
    parentTextView.getLocationOnScreen(parentTextViewLocation); 

    double parentTextViewTopAndBottomOffset = (
      //parentTextViewLocation[1] - 
      parentTextView.getScrollY() + 
        parentTextView.getCompoundPaddingTop() 
    ); 

    parentTextViewRect.top += parentTextViewTopAndBottomOffset; 
    parentTextViewRect.bottom += parentTextViewTopAndBottomOffset; 

    // In the case of multi line text, we have to choose what rectangle take 
    if (keywordIsInMultiLine){ 

     WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE); 
     Display display = wm.getDefaultDisplay(); 

     int screenHeight = display.getHeight(); 
     int dyTop = parentTextViewRect.top; 
     int dyBottom = screenHeight - parentTextViewRect.bottom; 
     boolean onTop = dyTop > dyBottom; 

     if (onTop){ 
      endXCoordinatesOfClickedText = textViewLayout.getLineRight(currentLineStartOffset); 
     } 
     else{ 
      parentTextViewRect = new Rect(); 
      textViewLayout.getLineBounds(currentLineEndOffset, parentTextViewRect); 
      parentTextViewRect.top += parentTextViewTopAndBottomOffset; 
      parentTextViewRect.bottom += parentTextViewTopAndBottomOffset; 
      startXCoordinatesOfClickedText = textViewLayout.getLineLeft(currentLineEndOffset); 
     } 

    } 

    parentTextViewRect.left += (
      parentTextViewLocation[0] + 
        startXCoordinatesOfClickedText + 
        parentTextView.getCompoundPaddingLeft() - 
        parentTextView.getScrollX() 
    ); 
    parentTextViewRect.right = (int) (
      parentTextViewRect.left + 
        endXCoordinatesOfClickedText - 
        startXCoordinatesOfClickedText 
    ); 


    canvas.drawLine(parentTextViewRect.left,parentTextViewRect.bottom+mStrokeWidth, parentTextViewRect.right, 
      parentTextViewRect.bottom+mStrokeWidth, mPaint); 
    super.onDraw(canvas); 
} 

}

attrs.xml est la suivante,

<declare-styleable name="UnderLine" > 
    <attr name="underlineWidthh" format="dimension" /> 
    <attr name="underlineColorr" format="color" /> 
    <attr name="underlineTextt" format="string" /> 
</declare-styleable> 

mise en page de l'échantillon comme suit,

<UnderLine 
    style="@style/textView" 
    android:gravity="top|center" 
    app:underlineColorr="@color/signup_bottom_darkWhite" 
    app:underlineWidthh="2dp" 
    app:underlineTextt="OPTING" 
    android:text="ON FREE PARKING + DISCOUNTED RATES \n BY OPTING IN"/> 

Je suis un débutant avec CustomView et moi avions créé cela avec l'aide de quelques réponses sur stackoverflow. S'il vous plaît ne suggère pas d'autre moyen de le faire.

Toute aide sera grandement appréciée.

j'avais développé mon propre point de vue, comme suit,

package com.example.reprator.underlinetextview; 

import android.content.Context; 
import android.content.res.TypedArray; 
import android.graphics.Canvas; 
import android.graphics.Paint; 
import android.graphics.Rect; 
import android.support.v7.widget.AppCompatTextView; 
import android.text.Layout; 
import android.util.AttributeSet; 

public class UnderlinedTextView extends AppCompatTextView { 

private Rect mRect; 
private Paint mPaint; 
private int mColor; 
private float mStrokeWidth; 
private float mMarginTop; 
private boolean isAllSelected; 
private int lineNumber; 
private int selectTextEachLine; 

public UnderlinedTextView(Context context) { 
    this(context, null, 0); 
} 

public UnderlinedTextView(Context context, AttributeSet attrs) { 
    this(context, attrs, 0); 
} 

public UnderlinedTextView(Context context, AttributeSet attrs, int defStyleAttr) { 
    super(context, attrs, defStyleAttr); 
    init(context, attrs, defStyleAttr); 
} 

private void init(Context context, AttributeSet attributeSet, int defStyle) { 

    float density = context.getResources().getDisplayMetrics().density; 

    TypedArray typedArray = context.obtainStyledAttributes(attributeSet, R.styleable.UnderlinedTextView, defStyle, 0); 
    mColor = typedArray.getColor(R.styleable.UnderlinedTextView_underlineColor, 0xFFFF0000); 
    mStrokeWidth = typedArray.getDimension(R.styleable.UnderlinedTextView_underlineWidth, density * 2); 
    mMarginTop = typedArray.getDimension(R.styleable.UnderlinedTextView_underlineMarginTop, density * 2); 
    isAllSelected = typedArray.getBoolean(R.styleable.UnderlinedTextView_underlineIsAll, false); 
    lineNumber = typedArray.getInteger(R.styleable.UnderlinedTextView_underlineNoLine, 1); 
    selectTextEachLine = typedArray.getInteger(R.styleable.UnderlinedTextView_underlineTextEachLine, 3); 
    typedArray.recycle(); 

    mRect = new Rect(); 
    mPaint = new Paint(); 
    mPaint.setStyle(Paint.Style.STROKE); 
    mPaint.setColor(mColor); //line mColor 
    mPaint.setStrokeWidth(mStrokeWidth); 
} 

public int getUnderLineColor() { 
    return mColor; 
} 

public void setUnderLineColor(int mColor) { 
    this.mColor = mColor; 
    invalidate(); 
} 

public float getUnderlineWidth() { 
    return mStrokeWidth; 
} 

public void setUnderlineWidth(float mStrokeWidth) { 
    this.mStrokeWidth = mStrokeWidth; 
    invalidate(); 
} 

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

    int h = (int) (getMeasuredHeight() + mMarginTop); 
    setMeasuredDimension(widthMeasureSpec, h); 
} 

@Override 
protected void onDraw(Canvas canvas) { 

    final Layout layout = getLayout(); 
    float x_start, x_stop; 
    int firstCharInLine, lastCharInLine; 

    int limit = isAllSelected ? getLineCount() : lineNumber; 
    for (int i = 0; i < limit; i++) { 
     int baseline = getLineBounds(i, mRect); 
     firstCharInLine = layout.getLineStart(i); 
     lastCharInLine = layout.getLineEnd(i); 

     int textHighlight = isAllSelected ? lastCharInLine - 1 : (firstCharInLine + selectTextEachLine); 
     x_start = layout.getPrimaryHorizontal(firstCharInLine); 
     x_stop = layout.getPrimaryHorizontal(textHighlight); 

     float y = baseline + mStrokeWidth + mMarginTop; 
     canvas.drawLine(x_start, y, x_stop, y, mPaint); 
    } 

    super.onDraw(canvas); 
} 

}

et mon attars.xml sont les suivantes,

<declare-styleable name="UnderlinedTextView"> 
    <attr name="underlineWidth" format="dimension" /> 
    <attr name="underlineMarginTop" format="dimension" /> 
    <attr name="underlineColor" format="color" /> 
    <attr name="underlineText" format="string" /> 
    <attr name="underlineIsAll" format="boolean" /> 
    <attr name="underlineNoLine" format="integer" /> 
    <attr name="underlineTextEachLine" format="integer" /> 
</declare-styleable>
