paint與文字設定相關的方法如下

        paint.setStrokeWidth(5);//畫筆寬度
        paint.setColor(Color.RED);//設定顏色
        paint.setAntiAlias(true);//抗鋸齒功能
        paint.setStyle(Paint.Style.FILL);//樣式
        paint.setTextAlign(Paint.Align.CENTER);//文字對齊方式
        paint.setTextSize(50);//設定文字大小
        paint.setFakeBoldText(true
 
);//設定是否為粗體
        paint.setUnderlineText(true);//設定下畫線
        paint.setTextSkewX(-0.25f);//字型傾斜度,一般設定為-0.25
        paint.setStrikeThruText(true);//設定帶有刪除線效果
        paint.setTextScaleX(2);//水平拉伸,高度不會變

示例程式碼

 /**
     * 填充樣式的區別
     * @param canvas
     */
    private void setStyle(Canvas canvas){
        Paint paint
 
=new Paint();
        paint.setColor(Color.RED);  //設定畫筆顏色

        paint.setStrokeWidth (5);//設定畫筆寬度
        paint.setAntiAlias(true); //指定是否使用抗鋸齒功能，如果使用，會使繪圖速度變慢
        paint.setTextSize(80);//設定文字大小

//繪圖樣式，設定為填充
        paint.setStyle(Paint.Style.FILL);
        canvas.drawText("床前明月光", 10,100, paint);
    }

    
 
/**
     * setTextAlign
     * @param canvas
     */
    private void setAlign(Canvas canvas){

        Paint paint=new Paint();
        paint.setColor(Color.RED);

        paint.setStrokeWidth (5);
        paint.setAntiAlias(true);
        paint.setTextSize(80);
        paint.setTextAlign(Paint.Align.RIGHT);

        canvas.drawText("床前明月光", 400,100, paint);
    }

    /**

     * @param canvas
     */
    private void setTextStyle(Canvas canvas){
        Paint paint=new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(80);
        canvas.drawText("床前明月光", 10,100, paint);

        paint.setFakeBoldText(true);//設定是否為粗體文字
        paint.setUnderlineText(true);//設定下劃線
        paint.setStrikeThruText(true);//設定帶有刪除線效果
        canvas.drawText("床前明月光", 10,250, paint);
    }

    /**
     *  設定字型樣式_字型傾斜度設定
     * @param canvas
     */
    private void setTextSkewX(Canvas canvas){
        Paint paint=new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(80);
        //正常樣式
        canvas.drawText("床前明月光", 10,100, paint);

        //向右傾斜
        paint.setTextSkewX(-0.25f);
        canvas.drawText("床前明月光", 10,200, paint);

        //向左傾斜
        paint.setTextSkewX(0.25f);
        canvas.drawText("床前明月光", 10,300, paint);
    }

    /**
     *  水平拉伸
     * @param canvas
     */
    private void setTextScaleX(Canvas canvas){
        Paint paint=new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(80);
        //正常樣式
        canvas.drawText("床前明月光", 10,100, paint);
        //拉伸兩倍
        paint.setTextScaleX(2);
        canvas.drawText("床前明月光", 10,200, paint);
    }

其他方法繪製

 /**
     *  普通繪製
     *
     * @param canvas
     */
    private void drawSubText(Canvas canvas) {
        Paint paint = new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(80);

        canvas.drawText("床前明月光", 2, 4, 10, 100, paint);
    }

    /**
     * 逐個指定文字位置
     */
    private void drawPosText(Canvas canvas) {
        Paint paint = new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(80);

        float[] pos = new float[]{80, 100,
                80, 200,
                80, 300,
                80, 400};
        canvas.drawPosText("床前明月", pos, paint); //pos繪製每個文字的具體位置,兩兩一組
    }

    /**
     * 沿路徑繪製
     * @param canvas
     */
    private void drawPathText(Canvas canvas) {
        Paint paint = new Paint();
        paint.setColor(Color.RED);
        paint.setStrokeWidth(5);
        paint.setTextSize(45);
        paint.setStyle(Paint.Style.STROKE);

        //先建立兩個相同的圓形路徑，並先畫出兩個路徑原圖
        Path circlePath = new Path();
        circlePath.addCircle(220, 300, 150, Path.Direction.CCW);//逆向繪製
        canvas.drawPath(circlePath, paint);//繪製出路徑原形

        Path circlePath2 = new Path();
        circlePath2.addCircle(600, 300, 150, Path.Direction.CCW);
        canvas.drawPath(circlePath2, paint);//繪製出路徑原形

        String string = "床前明月光,疑是地上霜";
        paint.setColor(Color.GREEN);
        //hoffset、voffset引數值全部設為0，看原始狀態是怎樣的
        canvas.drawTextOnPath(string, circlePath, 0, 0, paint);
        //第二個路徑，改變hoffset、voffset引數值
        canvas.drawTextOnPath(string, circlePath2, 80, 30, paint);

    }

    /**
     * 自字義字型
     * @param canvas
     */
    private void drawCustomFont(Canvas canvas){
        //自定義字型，，，迷你簡羅卜
        Paint paint=new Paint();
        paint.setColor(Color.RED);
        paint.setTextSize(60);

        AssetManager mgr= mContext.getAssets();//得到AssetManager
        //根據路徑得到Typeface
        Typeface typeface=Typeface.createFromAsset(mgr, "fonts/jian_luobo.ttf");
        paint.setTypeface(typeface);//設定字型樣式
        canvas.drawText("床前明月光,疑是地上霜",10,550, paint);
    }

defaultFromStyle函式

public static Typeface defaultFromStyle(int style)

該函式會指定字型樣式獲取對於的預設字型,取值如下

BOLD 粗體
BOLD_ITALIC粗斜體
ITALIC斜體
NORMAL 正常字型 預設

示例

       Typeface typeface = Typeface.defaultFromStyle(Typeface.BOLD);
        paint.setTypeface(typeface);

Typeface 中create函式

該函式直接通過指定字型名來載入系統中自帶的字型樣式,如果字型不存在,則使用系統樣式代替返回

示例:

        Typeface typeface = Typeface.create("宋體",Typeface.NORMAL);
        paint.setTypeface(typeface);
