Question

我有一个基于参数返回位图对象的方法。 if条件没有执行，我不知道究竟是什么问题，我试图在if条件中打印Log语句，这是不行的

public static Bitmap getWesternZodiacIcon(Context context,String westernZodiacSign)throws Exception{

      //Context context = null;

      Bitmap westernZodiacIcon = null;   

      if (westernZodiacSign.equals("Aries")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_aries);
        Log.v("westernZodiacIcon", "westernZodiacSign");
    }

      else if (westernZodiacSign.equals("Taurus")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_taurus);
          Log.v("westernZodiacIcon", westernZodiacSign);
    }

      else if (westernZodiacSign.equals("Gemini")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_gemini);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Cancer")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_cancer);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Leo")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_lion);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Virgo")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_virgin);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Libra")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_scales);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Scorpio")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_scorpion);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Sagittarius")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_sagittarius);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Capricorn")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_capricor);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Aquarius")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_aquarius);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      else if (westernZodiacSign.equals("Pisces")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_pisces);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }

      return westernZodiacIcon;
  }

Answer 1

您必须考虑所有案例。添加其他：

...
else if (westernZodiacSign.equals("Pisces")) {
          westernZodiacIcon=BitmapFactory.decodeResource(context.getResources(),R.drawable.zodiac_pisces);
          Log.v("westernZodiacIcon", westernZodiacSign);
        }
else {
          Log.v("westernZodiacIcon", "The null hypothesis for astrology is...");                  
}

另外，如方法签名中所示，可能会抛出异常，因此请尝试捕获并记录日志。
