, TextView's font size is best to use SP to do units, and view the source of TextView know that Android by default using the SP as the font size units. Usage Recommendations:According to Google's recommendation, pixels uniformly use the dip, the font unified use SPIn order for the user interface to display properly on the current and future display types, we recommend that you always use the

Android the PX , Dip , SP the DifferenceWe often set the length of the container in the layout of the page, but it is annoying to use which unit is the length.There are several types of description size areas that are supported in Android:PX (pixels)--Pixels: Different devices display the same effect, generally we hvga represent 320x480 pixels, this use more.Dip (device independent pixels)--equipment independent pixels: This is related to device hardw

[Dip: device independent pixels (device independent pixel ). Different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, HVGA, and QVGA without pixels. Px: pixels (pixels). Different devices have the same display effect. Generally, we use HVGA to represent 320x480 pixels, which is usually used. Pt: point, a standard unit of length, 1pt = 1/72 inch, used in the printing industry, very easy to use;

Recently, I've seen a lot of blog posts about conversion between DP-PX,PX-DP,SP-PX,PX-SP, and the way I used to do it was:1//Conversion dip for PX 2 public static int Convertdiporpx (context context, int dip) { 3 float scale = CONTEXT.GETRESOURC Es (). Getdisplaymetrics (). density; 4 return (int) (Dip*scale + 0.5f* (dip>=0?1:-1)); 5} 6 7//convert PX to dip 8 public static int Convertpxordip

²+ width pixels ²)/Screen diagonal inches dp:density-independent pixels, with 160PPI screen as standard, then 1dp=1px, DP and px conversion formula: dp*ppi/160 = px. such as 1DP x 320ppi/160 = 2px. sp:scale-independent pixels, which is the font unit for Android, is the standard 160PPI screen, when the font size is 100%, 1sp=1px. SP and px conversion Formula : sp*ppi/160 = px conclusion: px = dp*ppi/16

above parameter is that the dip is equal to the PX value.From the above, the visual designer in the WVGA (480x800) mode design, the recommended optimal spacing is: 12px, 18px, 24px, 30px, 36px, 42px, 48px, because the dip, PX value in the HVGA\WVGA corresponding are even, Each element can be the most stringent alignment.Second, SP and pxVisual measurement results between SP and px under WVGA (800x480):
