Question

我有一个自定义视图，它应该绘制一些底部对齐的文本。文字大小应为视图高度的50％。

我应该如何更改此代码才能正常工作？

@Override
protected void onDraw(Canvas canvas)
{
    float h = getMeasuredHeight();
    float textHeight = h*0.5f;
    paint.setTextSize(textHeight);
    String str = "Abcdefghijklm";

    paint.getTextBounds(str, 0, str.length(), bounds);
    float height = bounds.height();
    float yPos = height;
    canvas.drawText(str, 0, yPos, paint);
}

Answer 1

将您的yPos替换为：

v <- c(Decisive=2, Substantial=3, Positive=40, None=20)
paste0(names(v), "\n", v, "%")
# [1] "Decisive\n2%"    "Substantial\n3%" "Positive\n40%"   "None\n20%"
