//px转换成dip public int dip2px(Context context,
float dipValue){
final float scale = context.getResources().getDisplayMetrics().density;
return (
int)(dipValue * scale + 0.5f); }
下面是如何调用：
a1.setPadding(a1.getPaddingLeft()+
this.dip2px(
this, 5),a1.getPaddingTop(),a1.getPaddingRight(),a1.getPaddingBottom());
