What is the output if following code executed? public int pxToDp(int px) { DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics(); int dp = Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT)); return dp; } public int dpToPx(int dp) { DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics(); int px = Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT)); return px; }

Question:What is the output if following code executed? public int pxToDp(int px) { DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics(); int dp = Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT)); return dp; } public int dpToPx(int dp) { DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics(); int px = Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT)); return px; }

1.pxToDp() converts pixel into screen size value, and dpToPx() works via versa

2.pxToDp() converts pixel into screen status value, and dpToPx() works via versa

3.pxToDp() converts pixel into window DPI value, and dpToPx() works via versa
