'getDrawable(int)' is deprecated，getDrawable过时

来源：互联网发布：女狙击手知乎编辑：程序博客网时间：2024/05/18 02:24

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)

例如：

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

源码

 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);        }    }

可以看出也是做了高版本低版本兼容的
