获取字符串占的屏幕的宽度: - Paint mPaint = new Paint();
- int width = mPaint.measureText(hello); //在屏幕中所占的宽度
计算出当前绘制出来的字符串有多宽,可以这么来! 方法1:
- Paint pFont = new Paint();
- Rect rect = new Rect();
-
- //返回包围整个字符串的最小的一个Rect区域
- pFont.getTextBounds(str, 0, 1, rect);
-
- strwid = rect.width();
- strhei = rect.height();
方法2:
- Rect bounds = new Rect();
- String text = "Hello World";
- TextPaint paint;
-
- paint = findViewById(R.id.hello_world).getPaint();
- paint.getTextBounds(text, 0, text.length(), bounds);
- int width = bounds.width();
方法3:
- Paint pFont = new Paint();
- Rect rect = new Rect();
- pFont.getTextBounds("豆", 0, 1, rect);
- Log.v(TAG, "height:"+rect.height()+"width:"+rect.width());
