Android getColor 方法過時

• 過時方法

@ColorInt
@Deprecated
public int getColor(@ColorRes int id) throws NotFoundException {
    return getColor(id, null);
}

• 新增方法

@ColorInt
public int getColor(@ColorRes int id, @Nullable Theme theme) throws NotFoundException {
    final TypedValue value = obtainTempTypedValue();
    try
 
 {
        final ResourcesImpl impl = mResourcesImpl;
        impl.getValue(id, value, true);
        if (value.type >= TypedValue.TYPE_FIRST_INT
                && value.type <= TypedValue.TYPE_LAST_INT) {
            return value.data;
        } else if (value.type != TypedValue.TYPE_STRING) {
            throw
 
 new NotFoundException("Resource ID #0x" + Integer.toHexString(id)
                    + " type #0x" + Integer.toHexString(value.type) + " is not valid");
        }

        final ColorStateList csl = impl.loadColorStateList(this, value, id, theme);
        return csl.getDefaultColor();
    } finally {
        releaseTempTypedValue(value);
    }
}
 

• 推薦方法

ContextCompat.getColor(Context context, int id)

@ColorInt
public static int getColor(@NonNull Context context, @ColorRes int id) {
    if (Build.VERSION.SDK_INT >= 23) {
        return context.getColor(id);
    } else {
        return context.getResources().getColor(id);
    }
}

context.getColor(int id)

@ColorInt
public final int getColor(@ColorRes int id) {
    return getResources().getColor(id, getTheme());
}

context.getResources().getColor(int id);

@ColorInt
@Deprecated
public int getColor(@ColorRes int id) throws NotFoundException {
    return getColor(id, null);
}
