魅族手机显示tag,圆角起始处向右偏移了一点,导致右边宽度被裁剪一点,附解决方法

[woshiluoyong]

显示就是这个样子的,其他手机正常,就魅族16s pro这个手机显示异常,down下源码排查了好久,最终怀疑应该是魅族手机对tagview的测量有问题, 最后解决方法代码如下

代码也附上哈,避免github抽风图片显示不出来,其他原样无关的代码以点点点代替哈:

class TagView extends androidx.appcompat.widget.AppCompatTextView {
    .......
    public TagView(Context context, final int state, CharSequence text) {
                super(context);
                setGravity(Gravity.CENTER);
                setText(text);
                setMaxLines(1);
                setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize);
    
                mState = state;
    
                setClickable(isAppendMode);
                setFocusable(state == STATE_INPUT);
                setFocusableInTouchMode(state == STATE_INPUT);
                setHint(state == STATE_INPUT ? inputHint : null);
                setMovementMethod(state == STATE_INPUT ? ArrowKeyMovementMethod.getInstance() : null);
    
                ........
    
                invalidatePaint();
    
                setPadding(horizontalPadding, verticalPadding, horizontalPadding, verticalPadding);
    
                //setLayoutParams(new ViewGroup.LayoutParams(TagGroup.LayoutParams.WRAP_CONTENT, TagGroup.LayoutParams.WRAP_CONTENT));
                setLayoutParams(new ViewGroup.LayoutParams(StephenToolUtils.getStringPixelWidth(getPaint(), text.toString()) + (horizontalPadding * 2),
                        StephenToolUtils.getStringPixelMaxHeightForInt(getPaint()) + (verticalPadding * 2)));
      }
      ..............
        @Override
        protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
            int widthSize = MeasureSpec.getSize(widthMeasureSpec);
            int heightSize = MeasureSpec.getSize(heightMeasureSpec);
            setMeasuredDimension(widthSize, heightSize);
            //super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        }
        ..............
}

然后里面用到的StephenToolUtils相关方法如下:

//计算字符串的宽度(像素)
public static int getStringPixelWidth(Paint strPaint, String str) {
    return ((int) strPaint.measureText(str));
}

//计算字符串的高度(像素)
public static int getStringPixelHeight(Paint strPaint, String str) {
    Rect rect = new Rect();
    strPaint.getTextBounds(str, 0, str.length(), rect);
    return rect.height();
}

//计算字符串的高度(像素)(抵拢字体显示上下,没有空白)
public static int getStringPixelMinHeightForInt(Paint strPaint) {
    Paint.FontMetricsInt fontMetrics = strPaint.getFontMetricsInt();
    return fontMetrics.descent - fontMetrics.ascent;
}
//计算字符串的高度(像素)(字体显示上下处包含些许空白)
public static int getStringPixelMaxHeightForInt(Paint strPaint) {
    Paint.FontMetricsInt fontMetrics = strPaint.getFontMetricsInt();
    return fontMetrics.bottom - fontMetrics.top;
}

//计算字符串的高度(像素)(抵拢字体显示上下,没有空白)
public static float getStringPixelMinHeightForFloat(Paint strPaint) {
    Paint.FontMetrics fontMetrics = strPaint.getFontMetrics();
    return fontMetrics.descent - fontMetrics.ascent;
}
//计算字符串的高度(像素)(字体显示上下处包含些许空白)
public static float getStringPixelMaxHeightForFloat(Paint strPaint) {
    Paint.FontMetrics fontMetrics = strPaint.getFontMetrics();
    return fontMetrics.bottom - fontMetrics.top;
}
