我终于找到了根据 textview 的高度调整文本大小的代码。来源,但我不知道如何在这个函数中传递文本,我的文本来自另一个意图
public int getHeightOfMultiLineText(String text,int textSize, int maxWidth) {
TextPaint paint = new TextPaint();
paint.setTextSize(textSize);
int index = 0;
int linecount = 0;
while(index < text.length()) {
index += paint.breakText(text,index,text.length(),true,maxWidth,null);
linecount++;
}
Rect bounds = new Rect();
paint.getTextBounds("Yy", 0, 2, bounds);
// obtain space between lines
double lineSpacing = Math.max(0,((linecount - 1) * bounds.height()*0.25));
return (int)Math.floor(lineSpacing + linecount * bounds.height());
}
