转换颜色RGB到HEX

创建了一个方法转换三原色值到HEX值：

protected String convertRGBToHex(int r int g int b) {        String rFString rSString gFString gSString bFString bSString result;    int red green blue;    int rred rgreen rblue;    red = r / 16;    rred = r % 16;    if (red == 10) rFString = ""A"";    else if (red == 11) rFString = ""B"";    else if (red == 12) rFString = ""C"";    else if (red == 13) rFString = ""D"";    else if (red == 14) rFString = ""E"";    else if (red == 15) rFString = ""F"";    else rFString = String.valueOf(red);    if (rred == 10) rSString = ""A"";    else if (rred == 11) rSString = ""B"";    else if (rred == 12) rSString = ""C"";    else if (rred == 13) rSString = ""D"";    else if (rred == 14) rSString = ""E"";    else if (rred == 15) rSString = ""F"";    else rSString = String.valueOf(rred);    rFString = rFString + rSString;    green = g / 16;    rgreen = g % 16;    if (green == 10) gFString = ""A"";    else if (green == 11) gFString = ""B"";    else if (green == 12) gFString = ""C"";    else if (green == 13) gFString = ""D"";    else if (green == 14) gFString = ""E"";    else if (green == 15) gFString = ""F"";    else gFString = String.valueOf(green);    if (rgreen == 10) gSString = ""A"";    else if (rgreen == 11) gSString = ""B"";    else if (rgreen == 12) gSString = ""C"";    else if (rgreen == 13) gSString = ""D"";    else if (rgreen == 14) gSString = ""E"";    else if (rgreen == 15) gSString = ""F"";    else gSString = String.valueOf(rgreen);    gFString = gFString + gSString;    blue = b / 16;    rblue = b % 16;    if (blue == 10) bFString = ""A"";    else if (blue == 11) bFString = ""B"";    else if (blue == 12) bFString = ""C"";    else if (blue == 13) bFString = ""D"";    else if (blue == 14) bFString = ""E"";    else if (blue == 15) bFString = ""F"";    else bFString = String.valueOf(blue);    if (rblue == 10) bSString = ""A"";    else if (rblue == 11) bSString = ""B"";    else if (rblue == 12) bSString = ""C"";    else if (rblue == 13) bSString = ""D"";    else if (rblue == 14) bSString = ""E"";    else if (rblue == 15) bSString = ""F"";    else bSString = String.valueOf(rblue);    bFString = bFString + bSString;    result = ""#"" + rFString + gFString + bFString;    return result;}

我想知道能不能将这个string结果转换到int值，使用方法：

view.setBackgroundColor(0xF82619);

或者转换string到int：

view.setBackgroundColor(result);

解决方案

view.setBackgroundColor(Color.parseColor(""#0xF82619""));
