在自定義View中處理includeFontPadding可以通過以下步驟實現:
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomView);
boolean includeFontPadding = a.getBoolean(R.styleable.CustomView_includeFontPadding, true);
a.recycle();
if (includeFontPadding) {
setIncludeFontPadding(true);
} else {
setIncludeFontPadding(false);
}
private void drawText(Canvas canvas) {
Paint paint = new Paint();
paint.setTextSize(textSize);
paint.setColor(textColor);
paint.setAntiAlias(true);
if (includeFontPadding) {
paint.setIncludeFontPadding(true);
} else {
paint.setIncludeFontPadding(false);
}
canvas.drawText(text, x, y, paint);
}
通過以上步驟,可以在自定義View中處理includeFontPadding屬性,根據需要來控制字體間距的顯示效果。
