ViewGroup中获取屏幕高度和宽度
//获取屏幕高度宽度 @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); int measureWidth = MeasureSpec.getSize(widthMeasureSpec); int measureHeigt = MeasureSpec.getSize(heightMeasureSpec); }
Activity中获取屏幕高度和宽度
Display display=getWindowManager().getDefaultDisplay(); int width=display.getWidth(); int height=display.getHeight();
当然,现在上面这种获取方式已过时
我们可以使用以下方式
DisplayMetrics metrics = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(metrics); width = metrics.widthPixels; height = metrics.heightPixels;手机屏幕中心坐标获取
//获取屏幕高度宽度 @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); int measureWidth = MeasureSpec.getSize(widthMeasureSpec); int measureHeigt = MeasureSpec.getSize(heightMeasureSpec); //获取屏幕中心点 centerX = measureWidth/2; centerY = measureHeigt/2; }
