Android has many measurement units, such as commonly used dp, dip, sp, px, etc. Sometimes they need to be converted to each other. The following is a very convenient method:

For example, convert sp to px:


TypedValue. applyDimension (TypedValue. COMPLEX_UNIT_SP, value, metric );


The following is a prototype of the applyDimension function:


Float android. util. TypedValue. applyDimension (int unit, float value, DisplayMetrics metric)


You can use the following method to obtain metric

DisplayMetrics metric = new DisplayMetrics ();
GetWindowManager (). getDefaultDisplay (). getMetrics (metric );

 

You can change the unit:


TypedValue. COMPLEX_UNIT_DIP, TypedValue. COMPLEX_UNIT_DP
