Resources r = getResources(); 
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 14, r.getDisplayMetrics());

这种神奇的代码很有用（dp to px,sp to px...）

TypedValue有很多单位

    /** {@link #TYPE_DIMENSION} complex unit: Value is raw pixels. */
    public static final int COMPLEX_UNIT_PX = 0;
    /** {@link #TYPE_DIMENSION} complex unit: Value is Device Independent
     *  Pixels. */
    public static final int COMPLEX_UNIT_DIP = 1;
    /** {@link #TYPE_DIMENSION} complex unit: Value is a scaled pixel. */
    public static final int COMPLEX_UNIT_SP = 2;
    /** {@link #TYPE_DIMENSION} complex unit: Value is in points. */
    public static final int COMPLEX_UNIT_PT = 3;
    /** {@link #TYPE_DIMENSION} complex unit: Value is in inches. */
    public static final int COMPLEX_UNIT_IN = 4;
