推荐答案

看起来像有一个 measureText 方法可在<一href="http://developer.android.com/reference/android/graphics/Paint.html#measureText%28java.lang.String%29"><$c$c>Paint.我还发现了一个<一个href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/MeasureText.html">example:

Looks like there is a measureText method available on Paint. I also found an example:

mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setStrokeWidth(5);
mPaint.setStrokeCap(Paint.Cap.ROUND);
mPaint.setTextSize(64);
mPaint.setTypeface(Typeface.create(Typeface.SERIF, Typeface.ITALIC));
// ...
float w = mPaint.measureText(text, 0, text.length());
