Android常见尺寸的获取

代码：

                //获取控件尺寸（控件尺寸只有在事件里面可以获取到）
                TextView mTV = (TextView) findViewById(R.id.iv_view);
                int width = mTV.getWidth();
                int height = mTV.getHeight();

                //获取图片尺寸
                Drawable drawable = ContextCompat.getDrawable(this, R.drawable.about_logo);
                int width2 = drawable.getIntrinsicWidth();
                int height2 = drawable.getIntrinsicHeight();

                //获取屏幕尺寸
                DisplayMetrics dm = new DisplayMetrics();
                getWindowManager().getDefaultDisplay().getMetrics(dm);
                int width3 = dm.widthPixels;
                int height3 = dm.heightPixels;

结果：
