'getDrawable(int)' is deprecated，getDrawable过时

getDrawable(int)在API 21（5.0）已经过时了

5.0之后使用：

ContextCompat.getDrawable(context, R.drawable.your_drawable)
 

imageView.setImageDrawable(ContextCompat.getDrawable(this, R.drawable.icon));
 

      public static final Drawable getDrawable(Context context, @DrawableRes int id) {
             final int version = Build.VERSION.SDK_INT;
             if (version >= 21) {
                 return ContextCompatApi21.getDrawable(context, id);
              } else if (version >= 16) {
                 return context.getResources().getDrawable(id);
              } else {
                 // Prior to JELLY_BEAN, Resources.getDrawable() would not correctly
                 // retrieve the final configuration density when the resource ID
                 // is a reference another Drawable resource. As a workaround, try
                 // to resolve the drawable reference manually.
                 final int resolvedId;
                 synchronized (sLock) {
                     if (sTempValue == null) {
                          sTempValue = new TypedValue();
                      }
                      context.getResources().getValue(id, sTempValue, true);
                      resolvedId = sTempValue.resourceId;
                  }
                 return context.getResources().getDrawable(resolvedId);
              }
          }
